Configuring Settings for the Fault Collection Policy

Fault Collection Policy

The fault collection policy controls the lifecycle of a fault in a Cisco UCS instance, including when faults are cleared, the flapping interval (the length of time between the fault being raised and the condition being cleared), and the retention interval (the length of time a fault is retained in the system).

A fault in Cisco UCS has the following lifecycle:

1. A condition occurs in the system and Cisco UCS Manager raises a fault. This is the active state.
2. When the fault is alleviated, it is cleared if the time between the fault being raised and the condition being cleared is greater than the flapping interval, otherwise, the fault remains raised but its status changes to soaking-clear. Flapping occurs when a fault is raised and cleared several times in rapid succession. During the flapping interval the fault retains its severity for the length of time specified in the fault collection policy.
3. If the condition reoccurs during the flapping interval, the fault remains raised and its status changes to flapping. If the condition does not reoccur during the flapping interval, the fault is cleared.
4. When a fault is cleared, it is deleted if the clear action is set to delete, or if the fault was previously acknowledged; otherwise, it is retained until either the retention interval expires, or if the fault is acknowledged.
5. If the condition reoccurs during the retention interval, the fault returns to the active state. If the condition does not reoccur, the fault is deleted.

Configuring the Fault Collection Policy

Procedure

---

Step 1	In the Navigation pane, click the Admin tab.
Step 2	On the Admin tab, expand All > Faults, Events, and Audit Log.
Step 3	Click Settings.
Step 4	In the Work pane, complete the following fields in the Fault Collection Policy area: Name Description Flapping Interval field Flapping occurs when a fault is raised and cleared several times in rapid succession. To prevent this, the system does not allow a fault to change its state until this amount of time has elapsed since the last state change. If the condition reoccurs during the flapping interval, the fault returns to the active state. If the condition does not reoccur during the flapping interval, the fault is cleared. What happens at that point depends on the setting in the Clear Action field. Enter an integer between 5 and 3,600. The default is 10. Clear Action field This can be: retain—Cisco UCS Manager GUI displays the Length of time to retain cleared faults section. delete—The system immediately deletes all fault messages as soon as they are marked as cleared. Length of Time to Retain Cleared Faults Section Retention Interval field This can be: forever—The system leaves all cleared fault messages on the fabric interconnect regardless of how long they have been in the system. other—Cisco UCS Manager GUI displays the dd:hh:mm:ss field. dd:hh:mm:ss field The number of days, hours, minutes, and seconds that should pass before the system deletes a cleared fault message.
Step 5	Click Save Changes.

Configuring Settings for the Core File Exporter

Core File Exporter

Cisco UCS Manager uses the Core File Exporter to export core files as soon as they occur to a specified location on the network through TFTP. This functionality allows you to export the tar file with the contents of the core file.

Configuring the Core File Exporter

Procedure

---

Step 1	In the Navigation pane, click the Admin tab.
Step 2	On the Admin tab, expand All > Faults, Events, and Audit Log.
Step 3	Click Settings.
Step 4	In the Work pane, complete the following fields in the TFTP Core Exporter area: Name Description Admin State field This can be: enabled—If an error causes the server to perform a core dump, the system sends the core dump file via FTP to a given location. When this option is selected, Cisco UCS Manager GUI displays the other fields in this area that enable you to specify the FTP export options. disabled—Core dump files are not automatically exported. Description field A user-defined description of the core file. Port field The port number to use when exporting the core dump file via TFTP. Hostname field The hostname or IP address to connect with via TFTP. Note    If you use a hostname rather than an IP address, you must configure a DNS server in Cisco UCS Manager. Path field The path to use when storing the core dump file on the remote system.
Step 5	Click Save Changes.

Configuring the Syslog

Procedure

---

Step 1	In the Navigation pane, click the Admin tab.
Step 2	On the Admin tab, expand All > Faults, Events, and Audit Log.
Step 3	Click Syslog.
Step 4	In the Work pane, click the Syslog tab.
Step 5	In the Local Destinations area, complete the following fields: Name Description Console Section Admin State field This can be: enabled disabled Level field If the Admin State field is enabled, select the lowest message level that you want displayed. The system displays that level and above on the console. emergencies alerts critical Monitor Section Admin State field This can be: enabled disabled If Admin State is enabled, Cisco UCS Manager GUI displays the rest of the fields in this section. Level drop-down list If the Admin State field is enabled, select the lowest message level that you want displayed. The system displays that level and above on the monitor. emergencies alerts critical errors warnings notifications information debugging File Section Admin State field This can be: enabled disabled If Admin State is enabled, Cisco UCS Manager GUI displays the rest of the fields in this section. Level drop-down list Select the lowest message level that you want the system to store. The system stores that level and above in a file on the fabric interconnect. emergencies alerts critical errors warnings notifications information debugging Name field The name of the file in which the messages are logged. This name can be between 1 and 16 alphanumeric characters. You cannot use spaces or special characters. Size field The maximum size, in bytes, the file can be before Cisco UCS Manager GUI begins to write over the oldest messages with the newest ones. Enter an integer between 4096 and 4194304.
Step 6	In the Remote Destinations area, complete the following fields to configure up to three external logs that can store messages generated by the Cisco UCS components: Name Description Admin State field This can be: enabled disabled If Admin State is enabled, Cisco UCS Manager GUI displays the rest of the fields in this section. Level drop-down list Select the lowest message level that you want the system to store. The system stores that level and above in the remote file. emergencies alerts critical errors warnings notifications information debugging Hostname field The hostname or IP address on which the remote log file resides. Note    If you use a hostname rather than an IP address, you must configure a DNS server in Cisco UCS Manager. Facility drop-down list This can be: local0 local1 local2 local3 local4 local5 local6 local7
