Configuring Settings for the Fault Collection Policy

Fault Collection Policy

The fault collection policy controls the lifecycle of a fault in a Cisco UCS domain, 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:

A condition occurs in the system and Cisco UCS Manager raises a fault. This is the active state.
When the fault is alleviated, it enters a flapping or soaking interval that is designed to prevent flapping. 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.
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.
The cleared fault enters the retention interval. This interval ensures that the fault reaches the attention of an administrator even if the condition that caused the fault has been alleviated and the fault has not been deleted prematurely. The retention interval retains the cleared fault for the length of time specified in the fault collection policy.
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	The action the system takes when a fault is cleared. This can be one of the following: 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	If the Clear Action field is set to Retain, this is the length of time the system retains a fault once it is marked as cleared. This can be one of the following: 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.

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 one of the following:

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.

Enter up to 256 characters. You can use any characters or spaces except ^ (carat), \ (backslash), > (greater than), < (less than), ' (single quote), " (double quote), ` (accent mark), or = (equal sign).

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.
