12.2(8)T	Command output was expanded to show the status of the logging count facility ("Count and timestamp logging messages").
12.2(15)T	Command output was expanded to show the status of XML syslog formatting.
12.3(2)T	Command output was expanded (on supported software images) to show details about the status of system logging processed through the Embedded Syslog Manager (ESM). These lines appear as references to "filtering" or "filter modules".
12.3(2)XE	This command was integrated into Cisco IOS Release 12.3(2)XE.
12.2(25)S	This command was integrated into Cisco IOS Release 12.2(25)S.

Usage Guidelines

This command displays the state of syslog error and event logging, including host addresses, and which logging destinations (console, monitor, buffer, or host) logging is enabled. This command also displays Simple Network Management Protocol (SNMP) logging configuration parameters and protocol activity.

This command will also display the contents of the standard system logging buffer, if logging to the buffer is enabled. Logging to the buffer is enabled or disabled using the [no] logging buffered command. The number of system error and debugging messages in the system logging buffer is determined by the configured size of the syslog buffer. This size of the syslog buffer is also set using the logging buffered command.

To enable and set the format for syslog message timestamping, use the service timestamps log command.

If debugging is enabled (using any debug command), and the logging buffer is configured to include level 7 (debugging) messages, debug output will be included in the system log. Debugging output is not formatted like system error messages and will not be preceded by the percent symbol (%).

Examples

The following is sample output from the show logging command on a software image that supports the Embedded Syslog Manager (ESM) feature:

Router# show logging 

Syslog logging: enabled (10 messages dropped, 5 messages rate-limited,

                0 flushes, 0 overruns, xml disabled, filtering disabled)

    Console logging: level debugging, 31 messages logged, xml disabled,

                     filtering disabled

    Monitor logging: disabled

    Buffer logging: level errors, 36 messages logged, xml disabled,

                    filtering disabled

    Logging Exception size (8192 bytes)

    Count and timestamp logging messages: disabled

No active filter modules.

    Trap logging: level informational, 45 message lines logged

Log Buffer (8192 bytes):

Table 115 describes the significant fields shown in the display.

Table 115 show logging Field Descriptions

Field	Description
Syslog logging:	Shows general state of system logging (enabled or disabled), the status of logged messages (number of messages dropped, rate-limited, or flushed), and whether XML formatting or ESM filtering is enabled.
Console logging:	Logging to the console port. Shows "disabled" or, if enabled, the severity level limit, number of messages logged, and whether XML formatting or ESM filtering is enabled. Corresponds to the configuration of the logging console, logging console xml, or logging console filtered commands.
Monitor logging:	Logging to the monitor (all TTY lines). Shows "disabled" or, if enabled, the severity level limit, number of messages logged, and whether XML formatting or ESM filtering is enabled. Corresponds to the configuration of the logging monitor, logging monitor xml, or logging monitor filtered commands.
Buffer logging:	Logging to the standard syslog buffer. Shows "disabled" or, if enabled, the severity level limit, number of messages logged, and whether XML formatting or ESM filtering is enabled. Corresponds to the configuration of the logging buffered, logging buffered xml, or logging buffered filtered commands.
Trap logging:	Logging to a remote host (syslog collector). Shows "disabled" or, if enabled, the severity level limit, number of messages logged, and whether XML formatting or ESM filtering is enabled. (The word "trap" means a trigger in the system software for sending error messages to a remote host.) Corresponds to the configuration of the logging host command. The severity level limit is set using the logging trap command.
SNMP logging	Displays whether SNMP logging is enabled, the number of messages logged, and the retransmission interval. If not shown on your platform, use the show logging history command.
Logging Exception size (8192 bytes)	Corresponds to the configuration of the logging exception command.
Count and timestamp logging messages:	Corresponds to the configuration of the logging count command.
No active filter modules.	Appears if no syslog filter modules are configured with the logging filter command. Syslog filter modules are Tcl script files used when the Embedded Syslog Manager (ESM) is enabled. ESM is enabled when any of the filtered keywords are used in the logging commands. If configured, the URL and filename of configured syslog filter modules will appear at this position in the output. Syslog filter modules are executed in the order in which they appear here.
Log Buffer (8192 bytes):	The value in parentheses corresponds to the configuration of the logging buffered buffer-size command. If no messages are currently in the buffer, the output ends with this line. If messages are stored in the syslog buffer, they appear after this line.

The following example includes syslog messages from the system buffer, with timestamping. Note that in this example, the software image does not support XML formatting or ESM filtering of syslog messages.

The software clock keeps an "authoritative" flag that indicates whether the time is authoritative (believed to be accurate). If the software clock has been set by a timing source (for example, via NTP), the flag is set. If the time is not authoritative, it will be used only for display purposes. Until the clock is authoritative and the "authoritative" flag is set, the flag prevents peers from synchronizing to the software clock.

Table 116 describes the symbols that proceed the timestamp.

Table 116 Timestamping Symbols for syslog Messages

Symbol	Description	Example
*	Time is not authoritative: the software clock is not in sync or has never been set.	*15:29:03.158 UTC Tue Feb 25 2003:

Table 117 describes the logging level fields shown in the display.

Table 117 show logging summary Field Descriptions  

Field	Description
SLOT	Indicates the slot number of the line card. An asterisk next to the slot number indicates the GRP card whose error message counts are not displayed. For information on the GRP card, use the show logging command.
EMERG	Indicates that the system is unusable.
ALERT	Indicates that immediate action is needed.
CRIT	Indicates a critical condition.
ERROR	Indicates an error condition.
WARNING	Indicates a warning condition.
NOTICE	Indicates a normal but significant condition.
INFO	Indicates an informational message only.
DEBUG	Indicates a debugging message.

Related Commands

Command	Description
clear logging	Clears messages from the logging buffer.
logging count	Enables the error log count capability.
logging history size	Changes the number of syslog messages stored in the history table of the router.
logging linecard	Logs messages to an internal buffer on a line card and limits the logging messages displayed on terminal lines other than the console line to messages with a level at or above level.
service timestamps	Configures the system to timestamp debugging or logging messages.
show logging count	Displays a summary of system error messages (syslog messages) by facility and severity.
show logging xml	Displays the state of system logging and the contents of the XML-specific logging buffer.

show logging count

To display a summary of the number of times certain system error messages are occurring, use the show logging command in privileged EXEC mode.

show logging count

Syntax Description

This command has no arguments or keywords.

Command Modes

Privileged EXEC

Command History

Release	Modification
12.2(8)T	This command was introduced.

Usage Guidelines

To enable the error log count capability (syslog counting feature), use the logging count command in global configuration mode.

This feature works independently of the various settings of the other logging commands (such as [no] logging on, [no] logging buffered, and so on). In other words, turning off logging by other means does not stop the counting and timestamping from occurring.

This command displays information such as the number of times a particular system error message occurs and the time stamp of the last occurrence of the specified message. System error messages are grouped into logical units called "Facilities" based on Cisco IOS software components.

To determine if system error message counting is enabled, use the show logging command.

The service timestamps command configuration determines the timestamp format (shown in the "Last Time" column) of show logging count command output. There is not quite enough space for all options of the possible options (datetime, milliseconds, and timezone) of the service timestamps datetime command to be displayed at the same time. As a result, if msec is selected, timezone will not be displayed. If show-timezone is selected but not msec, then the time zone will be displayed.

Occasionally, the length of the message name plus the facility name contains too many characters to be printed on one line. The CLI attempts to keep the name and facility name on one line but, if necessary, the line will be wrapped, so that the first line contains the facility name and the second line contains the message name and the rest of the columns.

Examples

The following example shows the number of times syslog messages have occurred and the most recent time that each error message occurred. In this example, the show logging command is used to determine if the syslog counting feature is enabled:

Router# show logging | include count

Count and timestamp logging messages: enabled

Router# show logging count

Usage Guidelines

This command displays information about the syslog history table, such as the table size, the status of messages, and text of messages stored in the table. Messages stored in the table are governed by the logging history global configuration command.

Examples

The following example shows sample output from the show logging history command. In this example, notifications of severity level 5 (notifications) through severity level 0 (emergencies) are configured to be written to the logging history table.

Router# show logging history

Syslog History Table: 1 maximum table entries, 

saving level notifications or higher

0 messages ignored, 0 dropped, 15 table entries flushed,

SNMP notifications not enabled

  entry number 16: SYS-5-CONFIG_I

  Configured from console by console

  timestamp: 1110

Router#

Table 119 describes the significant fields shown in the output.

Table 119 show logging history Field Descriptions 

Field	Description
maximum table entry	Number of messages that can be stored in the history table. Set with the logging history size command.
saving level notifications <x> or higher	Level of messages that are stored in the history table and sent to the SNMP server (if SNMP notification is enabled). The severity level can be configured with the logging history command.
messages ignored	Number of messages not stored in the history table because the severity level is greater than that specified with the logging history command.
dropped	Number of messages that could not be processed due to lack of system resources. Dropped messages do not appear in the history table and are not sent to the SNMP server.
table entries flushed	Number of messages that have been removed from the history table to make room for newer messages.
SNMP notifications	Whether syslog traps of the appropriate level are sent to the SNMP server. The sending of syslog traps are enabled or disabled through the snmp-server enable traps syslog command.
entry number:	Number of the message entry in the history table. In the example above, the message "SYS-5-CONFIG_I Configured from console by console" indicates a syslog message consisting of the facility name (SYS), which indicates where the message came from, the severity level (5) of the message, the message name (CONFIG_I), and the message text.
timestamp	Time, based on the up time of the router, that the message was generated.

show memory debug incremental

To display information about memory leaks after a starting time has been established, use the show memory debug incremental command in privileged EXEC mode.

show memory debug incremental {allocations | leaks [lowmem] | status}

Syntax Description

allocations	Displays all memory blocks that were allocated after issuing the set memory debug incremental starting-time command.
leaks	Displays only memory that was leaked after issuing the set memory debug incremental starting-time command.
lowmem	(Optional) Forces the memory leak detector to work in low memory mode, making no memory allocations.
status	Displays all memory blocks that were allocated after issuing the set memory debug incremental starting-time command.

Command Modes

Privileged EXEC

Command History

Release	Modification
12.3(7)T	This command was introduced.

Usage Guidelines

The show memory debug incremental allocations command displays all the memory blocks that were allocated after the issue of a set memory debug incremental starting-time command. The displayed memory blocks are just memory allocations, they are not necessarily leaks.

The show memory debug incremental leaks command provides output similar to the show memory debug leaks command, except that it displays only memory that was leaked after the issue of a set memory debug incremental starting-time command.

The show memory debug incremental leaks lowmem command forces memory leak detection to work in low memory mode. The amount of time taken for analysis is considerably greater than that of normal mode. The output for this command is similar to the show memory debug leaks command, except that it displays only memory that was leaked after the issue of a set memory debug incremental starting-time command. You can use this command when you already know that normal mode memory leak detection will fail (perhaps by an unsuccessful previous attempt to invoke normal mode memory leak detection).

The show memory debug incremental status command displays whether a starting point for incremental analysis has been set and the elapsed time since then.

---

Note All memory leak detection commands invoke normal mode memory leak detection, except when the low memory option is specifically invoked by use of the lowmem keyword. In normal mode, if memory leak detection determines that there is insufficient memory to proceed in normal mode, it will display an appropriate message and switch to low memory mode

---

Examples

show memory debug leaks	Displays detected memory leaks.

show memory debug leaks

To display detected memory leaks, use the show memory debug leaks command in privileged EXEC mode.

show memory debug leaks [chunks | largest | lowmem | summary]

Syntax Description

chunks	(Optional) Displays the memory leaks in chunks.
largest	(Optional) Displays the top ten leaking allocator_pcs based on size, and the total amount of memory they have leaked.
lowmem	(Optional) Forces the memory leak detector to work in low memory mode, making no memory allocations.
summary	(Optional) Reports summarized memory leaks based on allocator_pc and size of the memory block.

Command Modes

Privileged EXEC

Command History

Release	Modification
12.3(8)T1	This command was introduced.
12.2(25)S	This command was integrated into Cisco IOS Release 12.2(25)S.

Usage Guidelines

If no optional keywords are specified, the show memory debug leaks command invokes normal mode memory leak detection and does not look for memory leaks in chunks.

The show memory debug leaks chunks command invokes normal mode memory leak detection and looks for leaks in chunks as well.

The show memory debug leaks largest command displays the top ten leaking allocator_pcs and the total amount of memory that they have leaked. Additionally, each time this command is invoked it remembers the previous invocation's report and compares it to the current invocation's report. If there are new entries in the current report they are tagged as "inconclusive." If the same entry appears in the previous invocation's report and the current invocation's report, the inconclusive tag is not added. It would be beneficial to run memory leak detection more than once and to consider only the consistently reported leaks.

The show memory debug leaks lowmem command forces memory leak detection to work in low memory mode. The amount of time taken for analysis is considerably greater than that of normal mode. The output for this command is similar to the show memory debug leaks command. You can use this command when you already know that normal mode memory leak detection will fail (perhaps by an unsuccessful previous attempt to invoke normal mode memory leak detection).

The show memory debug leaks summary command reports memory leaks based on allocator_pc and then on the size of the block.

---

Note All memory leak detection commands invoke normal mode memory leak detection, except when the low memory option is specifically invoked by use of the lowmem keyword. In normal mode, if memory leak detection determines that there is insufficient memory to proceed in normal mode, it will display an appropriate message and switch to low memory mode

component	(Optional) Name of the Cisco IOS software subsystem component that is the object of the event trace. To get a list of components that support event tracing in this release, use the monitor event-trace ? command.
all	Displays all event trace messages currently in memory for the specified component.
back	Specifies how far back from the current time you want to view messages. For example, you can gather messages from the last 30 minutes.
time	Length of time in hours and minutes format (hh:mm).
clock	Displays event trace messages starting from a specific clock time.
time	Time from which to display messages in hours and minutes format (hh:mm).
from-boot	Displays event trace messages starting from a specified number of seconds after booting.
seconds	Number of seconds since the networking device was last booted (uptime). To view the uptime, in seconds, enter the show monitor event-trace component from-boot ? command.
latest	Displays only the event trace messages since the last show monitor event-trace command was entered.
parameters	Displays the trace parameters. Currently, the only parameter displayed is the size (number of trace messages) of the trace file.

Release	Modification
12.0(18)S	This command was introduced.
12.2(8)T	This feature was integrated into Cisco IOS Release 12.2(8)T.

Usage Guidelines

Use the show monitor event-trace command to display trace message information.

The trace function is not locked while information is being displayed to the console, which means that new trace messages can accumulate in memory. If entries accumulate faster than they can be displayed, some messages can be lost. If this happens, the show monitor event-trace command will generate a message indicating that some messages might be lost; however, messages will continue to display on the console. If the number of lost messages is excessive, the show monitor event-trace command will stop displaying messages.

Examples

The following sample output illustrates the show monitor event-trace component command output for the IPC component. Notice that each trace message is numbered and is followed by a the timestamp (derived from the device uptime). Following the timestamp is the component-specific message data.

Router# show monitor event-trace ipc 

3667:  6840.016:Message type:3 Data=0123456789

3668:  6840.016:Message type:4 Data=0123456789

3669:  6841.016:Message type:5 Data=0123456789

3670:  6841.016:Message type:6 Data=0123456

To view trace information for all components configured for event tracing on the networking device, enter the show monitor event-trace all-traces command. In this example, separate output is provided for each event and message numbers are interleaved between the events.

Router# show monitor event-trace all-traces 

Test1 event trace:

3667: 6840.016:Message type:3 Data=0123456789

show parser dump

To display the CLI syntax options for all command modes or for a specified command mode, use the show parser dump command in privileged EXEC mode.

show parser dump {command-mode | all} [privilege-level level] [extended] [breakage]

Syntax Description

command-mode	A keyword indicating the command mode. The output will include the syntax for commands only in the specified command mode. The list of command mode keywords will vary depending on your software image. Use the show parser dump ? command to display the list of command mode keyword options. For further assistance determining the proper command mode, see the "Cisco IOS Command Modes" Release 12.2 document, available on Cisco.com.
all	Indicates that all commands in all modes should be displayed in the output. Caution This keyword generates a very large amount of output, which may exceed your system or buffer memory.
privilege-level level	(Optional) Lists CLI commands only with the privilege level specified in the level argument.
breakage	(Optional) Enables detection of potential parser chain syntax breakage. This keyword is intended for internal use.
extend	(Optional) Enables the extended display mode. The extended parser display shows the keyword and argument descriptions typically shown with the command-line help (? command). Note This keyword can produce a large amount of output.

Command Modes

Privileged EXEC

Command History

Release	Modification
12.2(4)T	This command was introduced.
12.2(13)T, 12.0(23)S	This command was enhanced to resolve certain execution errors.

Usage Guidelines

This command was developed to allow the exploration of the CLI command syntax without requiring the user to actually enter a specific mode and use the ? command line help.

---

Caution Use caution when entering this command with the all keyword. A large amount of output can be generated by this command, which may easily exceed buffer or system memory on smaller platforms. Also, some configuration modes have hundreds of valid commands. For large dumps, use of the redirection to a file using the | redirect URL syntax at the end of the command is highly recommended. (See the documentation for the show <command> redirect command for more information on using this command extension.)

---

Output for this command will show the syntax options for all commands available in the specified mode. The preceding number shows the privilege level associated with that command. For example, the line

15 type dhcp 

indicates that the type dhcp command has a privilege level of 15 assigned to it. For information about privilege levels, see the "Configuring Passwords and Privileges" chapter in the Cisco IOS Security Configuration Guide.

Any given command-line string should indicate the full syntax needed to make the command complete and valid. In other words, the command line string ends where the carriage return (Enter) could be entered, as indicated in command-line help by the <cr> syntax. You will typically see multiple forms of a command, each showing a valid syntax combination. For example, each of the following syntax combinations, as seen in the output of the show parser dump rtr | include dhcp command, are valid commands:

type dhcp dest-ipaddr <address> source-ipaddr <address> option <82-82> circuit-id <string> 

type dhcp dest-ipaddr <address> source-ipaddr <address> option <82-82> remote-id <string> 

type dhcp dest-ipaddr <address> source-ipaddr <address> option <82-82> subnet-mask 
<ipmask> 

type dhcp dest-ipaddr <address> source-ipaddr <address> option <82-82> 

type dhcp dest-ipaddr <address> source-ipaddr <address> 

type dhcp dest-ipaddr <address> 

type dhcp 

Use of the show command extensions | begin, | include, and | exclude are recommended for this command, as these extensions allow you to filter the output to show only the commands you are interested in. The redirection extensions | redirect, | append, and | tee allow you to redirect the output of this command to local or remote storage as a file.

As with most show commands, you can typically exit from the --More-- prompt back to EXEC mode using Ctrl-Z. For some connections, Ctrl-Shift-6 (Ctrl^) or Ctrl-Shift-6-X should be used instead.

show <command> exclude	Filters show command output so that it excludes lines that contain a particular regular expression.

show parser statistics

To displays statistics about the last configuration file parsed and the status of the Parser Cache feature, use the show parser statistics command in privileged EXEC mode.

show parser statistics

Syntax Description

This command has no arguments or keywords.

Command Modes

Privileged EXEC

Command History

Release	Modification
12.1(5)T	This command was introduced.

Usage Guidelines

The show parser statistics command displays two sets of data:

•The number of commands in the configuration file that was last copied into the running configuration, and the time it took for the system to parse them (a configuration file can be loaded into the running configuration at system startup, or by issuing commands such as the copy source running-config command).

•The status of the Parser Cache feature (enabled or disabled) and the number of command matches (indicated by hits/misses) since the system was started or since the parser cache was cleared.

The Parser Cache feature optimizes the parsing (translation and execution) of Cisco IOS software configuration command lines by remembering how to parse recently encountered command lines, decreasing the time required to process large configuration files.

Examples

The following example shows sample output from the show parser statistics command:

Router# show parser statistics

Last configuration file parsed:Number of Commands:1484, Time:1272 ms

Parser cache:disabled, 0 hits, 2 misses

In this example, the Parser Cache feature is disabled, but shows the hit/miss statistics for the two commands issued while the parser cache was last enabled.

Table 145 describes the key output fields.

Table 145 show parser statistics Output Fields

Last configuration file parsed:	Displays statistics on the last configuration file copied into the running configuration (at startup or using the copy command).
Number of commands:	The number of command lines in the last configuration file parsed.
Time:	Time (in milliseconds) taken for the system to load the last configuration file.
Parser cache:	Displays whether the Parser Cache feature is enabled or disabled, and the hit/miss statistics related to the feature. Statistics are stored since the initialization of the system, or since the last time the parser cache was cleared.
hits	Number of commands the parser cache was able to parse more efficiently by matching them to similar commands executed previously.
misses	Number of commands the parser cache was unable to match to previously executed commands. The performance enhancement provided by the Parser Cache feature cannot be applied to unmatched commands.

In the following example the show parser statistics command is used to compare the parse-time of a large configuration file with the Parser Cache feature disabled and enabled. In this example, a configuration file with 1484 access list commands is loaded into the running configuration.

Router# configure terminal

!parser cache is disabled

Router(config)# no parser cache

!configuration file is loaded into the running configuration

Router# copy slot0:acl_list running-config

.

.

.

Router# show parser statistics

Last configuration file parsed:Number of Commands:1484, Time:1272 ms

Parser cache:disabled, 0 hits, 2 misses

!the parser cache is reenabled

Router(config)# parser cache

!configuration file is loaded into the running configuration

Router# copy slot0:acl_list running-config

.

.

.

Router# show parser statistics

Last configuration file parsed:Number of Commands:1484, Time:820 ms

Parser cache:enabled, 1460 hits, 26 misses

These results show an improvement to the load time for the same configuration file from 1272 milliseconds (ms) to 820 ms when the Parser Cache feature was enabled. As indicated in the "hits" field of the show command output, 1460 commands were able to be parsed more efficiently by the parser cache.

Related Commands

Command	Description
clear parser cache	Clears the parse cache entries and hit/miss statistics stored for the Parser Cache feature.
parser cache	Enables or disables the Parser Cache feature.

Command Modes

Privileged EXEC

Command History

Release	Modification
12.0	This command was introduced.
12.2(2)T	The history keyword was added.
12.3(8)T	This command was enhanced to display Address Resolution Protocol (ARP) output.

Usage Guidelines

When you use the optional history keyword, output shows (in ASCII graphical form) the total CPU usage on the device over a period of time. Time periods are one minute, one hour, and 72 hours, displayed in increments of one second, one minute, and one hour, respectively. Maximum usage is measured and recorded every second; average usage is calculated on periods of more than one second.

Consistently high CPU utilization over an extended period of time indicates a problem and using the show processes cpu command is useful for troubleshooting. Also, you can use the output of this command in the Cisco Output Interpreter tool to display potential issues and fixes. Output Interpreter is available to registered users of Cisco.com who are logged in and have Java Script enabled.

The top two rows, read vertically, display the highest percentage of CPU utilization recorded during the time increment. In this example, the CPU utilization for the last minute recorded is 66 percent. The device may have reached 66 percent only once during that minute, or it may have reached 66 percent multiple times. The device records only the peak reached during the time increment and the average over the course of that increment.
