EEM 3.2 Event Registration Tcl Command Extensions

EEM Event Registration Tcl Command Extensions

Last Updated: December 29, 2012

The following conventions are used for the syntax documented on the Tcl command extension pages:

  • An optional argument is shown within square brackets, for example:

[type ?]

  • A question mark ? represents a variable to be entered.
  • Choices between arguments are represented by pipes, for example:

priority low|normal|high


Note


For all EEM Tcl command extensions, if there is an error, the returned Tcl result string contains the error information.

Note


Arguments for which no numeric range is specified take an integer from -2147483648 to 2147483647, inclusive.

event_register_appl

Registers for an application event. Use this Tcl command extension to run a policy when an application event is triggered following another policy's execution of an event_publish Tcl command extension; the event_publish command extension publishes an application event.

In order to register for an application event, a subsystem must be specified. Either a Tcl policy or the internal Embedded Event Manager (EEM) API can publish an application event. If the event is being published by a policy, the sub_system argument that is reserved for a policy is 798.

Syntax

event_register_appl [tag ?] sub_system ? type ? [queue_priority low|normal|high|last] [maxrun ?] [nice 0|1]

Arguments

tag

(Optional) String identifying a tag that can be used with the trigger Tcl command extension to support multiple event statements within a Tcl script.

sub_system

(Mandatory) Number assigned to the EEM policy that published the application event. The number is set to 798 because all other numbers are reserved for Cisco use. If this argument is not specified, all components are matched.

type

(Mandatory) Event subtype within the specified event. The sub_system and type arguments uniquely identify an application event. If this argument is not specified, all types are matched. If you specify this argument, you must choose an integer between 1 and 4294967295, inclusive.

There must be a match of component and type between the event_publish command extension and the event_register_applcommand extension in order for the publishing and registration to work.

queue_priority

(Optional) Priority level at which the script will be queued:

  • queue_priority low--Specifies that the script is to be queued at the lowest of the three priority levels.
  • queue_priority normal--Specifies that the script is to be queued at a priority level greater than low priority but less than high priority.
  • queue_priority high--Specifies that the script is to be queued at the highest of the three priority levels.
  • queue_priority last--Specifies that the script is to be queued at the lowest priority level.

If more than one script is registered with the "queue_priority_last" argument set, these scripts will execute in the order in which the events are published.

Note    The queue_priority argument specifies the queuing priority, but not the execution priority, of the script being registered.

If this argument is not specified, the default queuing priority is normal.

maxrun

(Optional) Maximum run time of the script (specified in SSSSSSSSSS[.MMM] format, where SSSSSSSSSS must be an integer representing seconds between 0 and 4294967295, inclusive, and where MMM must be an integer representing milliseconds between 0 and 999). If this argument is not specified, the default 20-second run-time limit is used.

nice

(Optional) Policy run-time priority setting. When the nice argument is set to 1, the policy is run at a run-time priority that is less than the default priority. The default value is 0.

If multiple conditions exist, the application event will be raised when all the conditions are satisfied.

Result String

None

Set _cerrno

No

Event_reqinfo

Event_reqinfo

"event_id %u event_type %u event_type_string {%s} event_pub_sec %u event_pub_msec %u"
"sub_system 0x%x type %u data1 {%s} data2 {%s} data3 {%s} data4 {%s}"

Event Type

Description

event_id

Unique number that indicates the ID for this published event. Multiple policies may be run for the same event, and each policy will have the same event_id.

event_type

Type of event.

event_type_string

An ASCII string that represents the name of the event for this event type.

event_pub_sec event_pub_msec

The time, in seconds and milliseconds, when the event was published to the Embedded Event Manager (EEM).

sub_system

Number assigned to the EEM policy that published the application event. Number is set to 798 because all other numbers are reserved for Cisco use.

type

Event subtype within the specified component.

data1 data2 data3 data4

Argument data that is passed to the application-specific event when the event is published. The data is character text, an environment variable, or a combination of the two.

event_register_cli

Registers for a CLI event. Use this Tcl command extension to run a policy when a CLI command of a specific pattern is entered based on pattern matching performed against an expanded CLI command.


Note


The user can enter an abbreviated CLI command, such as sh mem summary, and the parser will expand the command to show memory summaryto perform the matching.

Note


The functionality provided in the CLI event detector only allows a regular expression pattern match on a valid IOS CLI command itself. This does not include text after a pipe character when redirection is used.

Syntax

event_register_cli [tag ?] sync yes|no skip yes|no 
[occurs ?] [period ?] pattern ? [default ?] [enter] [questionmark] [tab] [mode]
[queue_priority low|normal|high|last] [maxrun ?] [nice 0|1]

Arguments

tag

(Optional) String identifying a tag that can be used with the trigger Tcl command extension to support multiple event statements within a Tcl script.

sync

(Mandatory) A "yes" means that the policy (the event publish) will run synchronously with the CLI command; a "no" means that the event publish will be performed asynchronously with the CLI command. The event detector will be notified when the policy completes running. The exit status of the policy indicates whether or not the CLI command should be executed: if the exit status is zero, which means that the policy is executed successfully, the CLI command will not be executed; otherwise, the CLI command will be executed.

skip

Mandatory if the sync argument is "no" and should not exist if the sync argument is "yes." If the skip argument is "yes," it means that the CLI command should not be executed. If the skip argument is "no," it means that the CLI command should be executed.

Caution   

When the skip argument is "yes," unintended results may be produced if the pattern match is made for configuration commands because the CLI command that matches the regular expression will not be executed.

occurs

(Optional) The number of occurrences before the event is raised. If this argument is not specified, the event is raised on the first occurrence. If this argument is specified, it must be an integer between 1 and 4294967295, inclusive.

period

(Optional) Specifies a backward looking time window in which all CLI events must occur (the occurs clause must be satisfied) in order for an event to be published (specified in SSSSSSSSSS[.MMM] format, where SSSSSSSSSS must be an integer representing seconds between 0 and 4294967295, inclusive, and where MMM must be an integer representing milliseconds between 0 and 999). If this argument is not specified, the most recent event is used.

pattern

(Mandatory) Specifies the regular expression used to perform the CLI command pattern match.

default

(Optional) The time period during which the CLI event detector waits for the policy to exit (specified in SSSSSSSSSS[.MMM] format, where SSSSSSSSSS must be an integer representing seconds between 0 and 4294967295, inclusive, and where MMM must be an integer representing milliseconds between 0 and 999). If the default time period expires before the policy exits, the default action will be executed. The default action is to run the command. If this argument is not specified, the default time period is set to 30 seconds.

queue_priority

(Optional) Priority level at which the script will be queued:

  • queue_priority low--Specifies that the script is to be queued at the lowest of the three priority levels.
  • queue_priority normal--Specifies that the script is to be queued at a priority level greater than low priority but less than high priority.
  • queue_priority high--Specifies that the script is to be queued at the highest of the three priority levels.
  • queue_priority last--Specifies that the script is to be queued at the lowest priority level.

If more than one script is registered with the "queue_priority_last" argument set, these scripts will execute in the order in which the events are published.

Note    The queue_priority argument specifies the queuing priority, but not the execution priority, of the script being registered.

If this argument is not specified, the default queuing priority is normal.

enter

(Optional) Specifies to perform the event match when the user presses the Enter key. When this parameter is used, the input string will not be expanded before matching.

questionmark

(Optional) Specifies to perform the event match when the user presses the ? key. When this parameter is used, the input string will not be expanded before matching.

tab

(Optional) Specifies to perform the event match when the user presses the Tab key. When this parameter is used, the input string will not be expanded before matching.

mode

(Optional) Events will only be generated when the parser is in the specified parser mode. The available modes can be listed using the show parser dump CLI command. The mode parameter is checked when any one of the optional parameters--enter, questionmark, or tab-- is specified.

maxrun

(Optional) Maximum run time of the script (specified in SSSSSSSSSS[.MMM] format, where SSSSSSSSSS must be an integer representing seconds between 0 and 4294967295, inclusive, and where MMM must be an integer representing milliseconds between 0 and 999). If this argument is not specified, the default 20-second run-time limit is used.

nice

(Optional) Policy run-time priority setting. When the nice argument is set to 1, the policy is run at a run-time priority that is less than the default priority. The default value is 0.

If multiple conditions are specified, the CLI event will be raised when all the conditions are matched.

Result String

None

Set _cerrno

No


Note


This policy runs before the CLI command is executed. For example, suppose policy_CLI is registered to run when the copy command is entered. When the copy command is entered, the CLI event detector finds a pattern match and triggers this policy to run. When the policy execution ends, the CLI event detector determines if the copy command needs to be executed according to "sync", "skip" (set in the policy), and the exit status of the policy execution if needed.

Event_reqinfo

event_register_counter

Registers for a counter event as both a publisher and a subscriber. Use this Tcl command extension to run a policy on the basis of a named counter crossing a threshold. This event counter, as a subscriber, identifies the name of the counter to which it wants to subscribe and depends on another policy or another process to actually manipulate the counter. For example, let policyB act as a counter policy, whereas policyA (although it does not need to be a counter policy) uses register_counter, counter_modify, or unregister_counter Tcl command extensions to manipulate the counter defined in policyB.

Syntax

name

(Mandatory) The name of the interface being monitored, for example, Ethernet 0/0. Abbreviations and spaces are not allowed.

parameter

(Mandatory) The name of the counter being compared as follows:

  • input_errors--Includes runts, giants, no buffer, CRC, frame, overrun, and ignored counts. Other input-related errors can also cause the input errors count to be increased, and some datagrams may have more than one error; therefore, this sum may not balance with the sum of enumerated input error counts.
  • input_errors_crc--Cyclic redundancy checksum generated by the originating LAN station or far-end device does not match the checksum calculated from the data received.
  • input_errors_frame--Number of packets received incorrectly having a CRC error and a noninteger number of octets.
  • input_errors_overrun--Number of times the receiver hardware was unable to hand received data to a hardware buffer because the input rate exceeded the receiver's ability to handle the data.
  • input_packets_dropped--Number of packets dropped because of a full input queue.
  • interface_resets--Number of times that an interface has been completely reset.
  • output_buffer_failures--Number of failed buffers and number of buffers swapped out.
  • output_buffer_swappedout--Number of packets swapped to DRAM.

parameter (continued)

  • output_errors--Sum of all errors that prevented the final transmission of datagrams out of the interface being examined. Note that this may not balance with the sum of the enumerated output errors, because some datagrams may have more than one error, and others may have errors that do not fall into any of the specifically tabulated categories.
  • output_errors_underrun--Number of times that the transmitter has been running faster than the device can handle.
  • output_packets_dropped--Number of packets dropped because of a full output queue.
  • receive_broadcasts--Number of broadcast or multicast packets received by the interface.
  • receive_giants--Number of packets that are discarded because they exceed the maximum packet size of the medium.
  • receive_rate_bps--Interface receive rate in bytes per second.
  • receive_rate_pps--Interface receive rate in packets per second.
  • receive_runts--Number of packets that are discarded because they are smaller than the minimum packet size of the medium.
  • receive_throttle--Number of times that the receiver on the port was disabled, possibly because of buffer or processor overload.
  • reliability--Reliability of the interface as a fraction of 255 (255/255 is 100 percent reliability), calculated as an exponential average over 5 minutes.
  • rxload--Receive rate of the interface as a fraction of 255 (255/255 is 100 percent).
  • transmit_rate_bps--Interface transmit rate in bytes per second.
  • transmit_rate_pps--Interface transmit rate in packets per second.
  • txload--Transmit rate of the interface as a fraction of 255 (255/255 is 100 percent).

entry_op

(Mandatory) The comparison operator used to compare the current interface value with the entry value; if true, an event will be raised and event monitoring will be disabled until exit criteria are met.

entry_val

(Mandatory) The value at which the event will be triggered.

entry_val_is_increment

(Mandatory) If TRUE, the entry_val field is treated as an incremental difference and is compared with the difference between the current counter value and the value when the event was last true (the first polled sample if this is a new event). A negative value checks the incremental difference for a counter that is decreasing. If FALSE, the entry_val field is compared against the current counter value.

Note    This keyword has been deprecated, and if specified, the syntax is converted into equivalent entry-type keyword syntax.

entry-type

Specifies a type of operation to be applied to the object ID specified by the entry-val argument.

Value is defined as the actual value of the entry-val argument.

Increment uses the entry-val field as an incremental difference and the entry-valis compared with the difference between the current counter value and the value when the event was last triggered (or the first polled sample if this is a new event). A negative value checks the incremental difference for a counter that is decreasing.

Rate is defined as the average rate of change over a period of time. The time period is the average-factor value multiplied by the poll-interval value. At each poll interval the difference between the current sample and the previous sample is taken and recorded as an absolute value. An average of the previous average-factor value samples is taken to be the rate of change.

exit_comb

(Optional) Used to indicate the combination of exit condition tests required to rearm the event trigger; if the and operator is specified, both exit value and exit time tests must be true to cause rearm; if the or operator is specified, either exit value or exit time tests can be true to cause event monitoring to be rearmed.

exit_op

(Optional) The comparison operator used to compare the current interface value with the exit value; if true, event monitoring for this event will be reenabled.

exit_val

(Optional) The value at which the event is rearmed to be monitored again.

exit_val_is_increment

(Optional) If TRUE, the exit_val field is treated as an incremental difference and is compared with the difference between the current counter value and the value when the event was last true. A negative value checks the incremental difference for a counter that is decreasing. If FALSE, the exit_val field is compared against the current counter value.

Note    In Cisco IOS Release 12.4(20)T, this keyword is deprecated, and if specified, the syntax is converted into equivalent exit-type keyword syntax.

exit-type

(Optional) Specifies a type of operation to be applied to the object ID specified by the exit-val argument. If not specified, the value is assumed.

Value is defined as the actual value of the exit-val argument.

Increment uses the exit-val field as an incremental difference and the exit-val is compared with the difference between the current counter value and the value when the event was last triggered (or the first polled sample if this is a new event). A negative value checks the incremental difference for a counter that is decreasing.

Rate is defined as the average rate of change over a period of time. The time period is the average-factor value multiplied by the poll-interval value. At each poll interval the difference between the current sample and the previous sample is taken and recorded as an absolute value. An average of the previous average-factor value samples is taken to be the rate of change.

exit_time

(Optional) The time period at which the event is rearmed to be monitored again (specified in SSSSSSSSSS[.MMM] format, where SSSSSSSSSS must be an integer representing seconds between 0 and 4294967295, inclusive, and where MMM must be an integer representing milliseconds between 0 and 999).

The poll interval value must not be less than 1 second. The default is 1 second.

average-factor

(Optional) Number in the range from 1 to 64 used to calculate the period used for rate-based calculations. The average-factor value is multiplied by the poll-interval value to derive the period in milliseconds. The minimum average factor value is 1.

queue_priority

(Optional) Priority level at which the script will be queued:

  • queue_priority low--Specifies that the script is to be queued at the lowest of the three priority levels.

  • queue_priority last--Specifies that the script is to be queued at the lowest priority level.

If more than one script is registered with the "queue_priority_last" argument set, these scripts will execute in the order in which the events are published.

Note    The queue_priority argument specifies the queuing priority, but not the execution priority, of the script being registered.

If this argument is not specified, the default queuing priority is normal.

maxrun

(Optional) Maximum run time of the script (specified in SSSSSSSSSS[.MMM] format, where SSSSSSSSSS must be an integer representing seconds between 0 and 4294967295, inclusive, and where MMM must be an integer representing milliseconds between 0 and 999).

event_register_snmp

Registers for a Simple Network Management Protocol (SNMP) statistics event. Use this Tcl command extension to run a policy when a given counter specified by an SNMP object ID (oid) crosses a defined threshold.

Syntax

event_register_snmp [tag ?] oid ? get_type exact|next
entry_op gt|ge|eq|ne|lt|le entry_val ?
entry_type value|increment|rate
[exit_comb or|and]
[exit_op gt|ge|eq|ne|lt|le] [exit_val ?]
[exit_type value|increment|rate]
[exit_time ?] poll_interval ? [average_factor ?]
[queue_priority low|normal|high|last]
[maxrun ?] [nice 0|1]

Arguments

tag

(Optional) String identifying a tag that can be used with the trigger Tcl command extension to support multiple event statements within a Tcl script.

oid

(Mandatory) OID number of data element in SNMP dot notation (for example, 1.3.6.1.2.1.2.1.0). The types of OIDs allowed are:

  • COUNTER_TYPE
  • COUNTER_64_TYPE
  • GAUGE_TYPE
  • INTEGER_TYPE
  • OCTET_PRIM_TYPE
  • OPAQUE_PRIM_TYPE
  • TIME_TICKS_TYPE

entry_op

(Mandatory) Entry comparison operator used to compare the current OID data value with the entry value; if true, an event will be raised and event monitoring will be disabled until exit criteria are met.

get_type

(Mandatory) Type of SNMP get operation that needs to be applied to the OID specified. If the get_type argument is "exact," the value of the specified OID is retrieved; if the get_type argument is "next," the value of the lexicographical successor to the specified OID is retrieved.

entry_val

(Mandatory) Value with which the current oid data value should be compared to decide if the SNMP event should be raised.

entry-type

Specifies a type of operation to be applied to the object ID specified by the entry-val argument.

Value is defined as the actual value of the entry-val argument.

Increment uses the entry-val field as an incremental difference and the entry-valis compared with the difference between the current counter value and the value when the event was last triggered (or the first polled sample if this is a new event). A negative value checks the incremental difference for a counter that is decreasing.

Rate is defined as the average rate of change over a period of time. The time period is the average-factor value multiplied by the poll-interval value. At each poll interval the difference between the current sample and the previous sample is taken and recorded as an absolute value. An average of the previous average-factor value samples is taken to be the rate of change.

exit_comb

(Optional) Exit combination operator used to indicate the combination of exit condition tests required to decide if the exit criteria are met so that the event monitoring can be reenabled. If it is "and," both exit value and exit time tests must be passed to meet the exit criteria. If it is "or," either exit value or exit time tests can be passed to meet the exit criteria. When exit_comb is "and," exit_op, and exit_val (exit_time) must exist. When exit_comb is "or," (exit_op and exit_val) or (exit_time) must exist.

exit_op

(Optional) Exit comparison operator used to compare the current oid data value with the exit value; if true, event monitoring for this event will be reenabled.

exit_val

(Optional) Value with which the current oid data value should be compared to decide if the exit criteria are met.

exit-type

(Optional) Specifies a type of operation to be applied to the object ID specified by the exit-val argument. If not specified, the value is assumed.

Value is defined as the actual value of the exit-val argument.

Increment uses the exit-val field as an incremental difference and the exit-val is compared with the difference between the current counter value and the value when the event was last triggered (or the first polled sample if this is a new event). A negative value checks the incremental difference for a counter that is decreasing.

Rate is defined as the average rate of change over a period of time. The time period is the average-factor value multiplied by the poll-interval value. At each poll interval the difference between the current sample and the previous sample is taken and recorded as an absolute value. An average of the previous average-factor value samples is taken to be the rate of change.

exit_time

(Optional) Number of POSIX timer units after an event is raised when event monitoring will be enabled again. Specified in SSSSSSSSSS[.MMM] format where SSSSSSSSSS must be an integer number representing seconds between 0 and 4294967295, inclusive. MMM represents milliseconds and must be an integer number between 0 and 999.

poll_interval

(Mandatory) Interval between consecutive polls in POSIX timer units. Currently the interval is forced to be at least 1 second (specified in SSSSSSSSSS[.MMM] format, where SSSSSSSSSS must be an integer representing seconds between 0 and 4294967295, inclusive, and where MMM must be an integer representing milliseconds between 0 and 999).

average-factor

(Optional) Number in the range from 1 to 64 used to calculate the period used for rate-based calculations. The average-factor value is multiplied by the poll-interval value to derive the period in milliseconds. The minimum average factor value is 1.

queue_priority

(Optional) Priority level at which the script will be queued:

  • queue_priority low--Specifies that the script is to be queued at the lowest of the three priority levels.
  • queue_priority normal--Specifies that the script is to be queued at a priority level greater than low priority but less than high priority.
  • queue_priority high--Specifies that the script is to be queued at the highest of the three priority levels.
  • queue_priority last--Specifies that the script is to be queued at the lowest priority level.

If more than one script is registered with the "queue_priority_last" argument set, these scripts will execute in the order in which the events are published.

Note    The queue_priority argument specifies the queuing priority, but not the execution priority, of the script being registered.

If this argument is not specified, the default queuing priority is normal.

maxrun

(Optional) Maximum run time of the script (specified in SSSSSSSSSS[.MMM] format, where SSSSSSSSSS must be an integer representing seconds between 0 and 4294967295, inclusive, and where MMM must be an integer representing milliseconds between 0 and 999). If this argument is not specified, the default 20-second run-time limit is used.

Note


Both the CRON and absolute time specifications work on local time.

Syntax

event_register_timer [tag ?] watchdog|countdown|absolute|cron 
[name ?] [cron_entry ?] 
[time ?] 
[queue_priority low|normal|high|last] [maxrun ?]
[nice 0|1]

Arguments

tag

(Optional) String identifying a tag that can be used with the trigger Tcl command extension to support multiple event statements within a Tcl script.

watchdog

(Mandatory) Watchdog timer.

countdown

(Mandatory) Countdown timer.

absolute

(Mandatory) Absolute timer.

cron

(Mandatory) CRON timer.

name

(Optional) Name of the timer.

cron_entry

(Optional) Must be specified if the CRON timer type is specified. Must not be specified if any other timer type is specified. A cron_entry is a partial UNIX crontab entry (the first five fields) as used with the UNIX CRON daemon.

A cron_entry specification consists of a text string with five fields. The fields are separated by spaces. The fields represent the time and date when CRON timer events will be triggered. The fields are described in the table titled "Time and Date When CRON Events Will Be Triggered."

Ranges of numbers are allowed. Ranges are two numbers separated with a hyphen. The specified range is inclusive. For example, 8-11 for an hour entry specifies execution at hours 8, 9, 10, and 11.

A field may be an asterisk (*), which always stands for "first-last."

Lists are allowed. A list is a set of numbers (or ranges) separated by commas. Examples: "1,2,5,9" and "0-4,8-12".

Step values can be used in conjunction with ranges. Following a range with "/<number>" specifies skips of the number's value through the range. For example, "0-23/2" can be used in the hour field to specify an event that is triggered every other hour. Steps are also permitted after an asterisk, so if you want to say "every two hours", use "*/2".

Names can also be used for the month and the day of week fields. Use the first three letters of the particular day or month (case does not matter). Ranges or lists of names are not allowed.

The day on which a timer event is triggered can be specified by two fields: day of month and day of week. If both fields are restricted (that is, are not *), an event will be triggered when either field matches the current time. For example, "30 4 1,15 * 5" would cause an event to be triggered at 4:30 a.m. on the 1st and 15th of each month, plus every Friday.

Instead of the first five fields, one of seven special strings may appear. These seven special strings are described in the table titled "Special Strings for cron_entry."

Example 1: "0 0 1,15 * 1" would trigger an event at midnight on the 1st and 15th of each month, as well as on every Monday. To specify days by only one field, the other field should be set to *; "0 0 * * 1" would trigger an event at midnight only on Mondays.

Example 2: "15 16 1 * *" would trigger an event at 4:15 p.m. on the first day of each month.

Example 3: "0 12 * * 1-5" would trigger an event at noon on Monday through Friday of each week.

Example 4: "@weekly" would trigger an event at midnight once a week on Sunday.

time

(Optional) Must be specified if a timer type other than CRON is specified. Must not be specified if the CRON timer type is specified. For watchdog and countdown timers, the number of seconds and milliseconds until the timer expires; for the absolute timer, the calendar time of the expiration time. Time is specified in SSSSSSSSSS[.MMM] format, where SSSSSSSSSS must be an integer representing seconds between 0 and 4294967295, inclusive, and where MMM must be an integer representing milliseconds between 0 and 999. An absolute expiration date is the number of seconds and milliseconds since January 1, 1970. If the date specified has already passed, the timer expires immediately.

queue_priority

(Optional) Priority level at which the script will be queued:

  • queue_priority low--Specifies that the script is to be queued at the lowest of the three priority levels.
  • queue_priority normal--Specifies that the script is to be queued at a priority level greater than low priority but less than high priority.
  • queue_priority high--Specifies that the script is to be queued at the highest of the three priority levels.
  • queue_priority last--Specifies that the script is to be queued at the lowest priority level.

If more than one script is registered with the "queue_priority_last" argument set, these scripts will execute in the order in which the events are published.

Note    The queue_priority argument specifies the queuing priority, but not the execution priority, of the script being registered.

If this argument is not specified, the default queuing priority is normal.

maxrun

(Optional) Maximum run time of the script (specified in SSSSSSSSSS[.MMM] format, where SSSSSSSSSS must be an integer representing seconds between 0 and 4294967295, inclusive, and where MMM must be an integer representing milliseconds between 0 and 999). If this argument is not specified, the default 20-second run-time limit is used.

nice

(Optional) Policy run-time priority setting. When the nice argument is set to 1, the policy is run at a run-time priority that is less than the default priority. The default value is 0.

event_register_timer_subscriber

Registers for a timer event as a subscriber. Use this Tcl command extension to identify the name of the timer to which the event timer, as a subscriber, wants to subscribe. The event timer depends on another policy or another process to actually manipulate the timer. For example, let policyB act as a timer subscriber policy, but policyA (although it does not need to be a timer policy) uses register_timer, timer_arm, or timer_cancel Tcl command extensions to manipulate the timer referenced in policyB.

If the sec and msec variables are specified as 0 or are unspecified in the event registration Tcl command extension, the avail is in the latest total used memory sample. If a time window is specified and is greater than zero in the event registration Tcl command extension, the avail is the total used memory utilization in the specified time window.

diff

If the sec and msec variables are specified as 0 or are unspecified in the event registration Tcl command extension, the diff is the percentage difference between the first total used memory sample ever collected and the latest total used memory sample. If a time window is specified and is greater than zero in the event registration Tcl command extension, the diff is the percentage difference between the oldest and latest total used memory utilization in the specified time window.

sec msec

If the sec and msec variables are specified as 0 or are unspecified in the event registration Tcl command extension, they are both 0. If a time window is specified and is greater than zero in the event registration Tcl command extension, the sec and msec variables are the actual time difference between the time stamps of the oldest and latest samples in this time window.

If the is_percent argument is FALSE, and the sec and msec arguments are specified as 0 or are unspecified in the event registration Tcl command extension:

  • used is the total used memory in the latest sample,
  • avail is the total available memory in the latest sample,
  • diff is 0,
  • sec and msec are both 0,

If the is_percent argument is FALSE, and a time window is specified as greater than zero in the event registration Tcl command extension:

  • used is the averaged total used memory sample value in the specified time window,
  • avail is 0,
  • diff is 0,
  • sec and msec are both the actual time difference between the time stamps of the oldest and latest total used memory samples in this time window,

If the is_percent argument is TRUE, and a time window is specified as greater than zero in the event registration Tcl command extension:

  • used is 0.
  • avail is 0.
  • diff is the percentage difference between the oldest and latest total used memory samples in the specified time window.
  • sec and msec are both the actual time difference between the time stamps of the oldest and latest total used memory samples in this time window.

If the is_percent argument is TRUE, and the sec and msec arguments are specified as 0 or are unspecified in the event registration Tcl command extension:

  • used is 0.
  • avail is 0.
  • diff is the percentage difference between the first total used memory sample ever collected and the latest total used memory sample.
  • sec and msec are the actual time difference between the time stamps of the first total used memory sample ever collected and the latest total used memory sample.
