Checkpointing Logs; Saving Log Files - Cisco ASR 5000 Administration Manual

Checkpointing Logs

• upper_percent and lower_percent are expressed as integers from 0 to 100. Default value for upper_percent
• threshold poll ls-logs-volume interval sets the polling interval in seconds. The default interval is 300
• threshold monitoring ls-logs-volume enables or disables this feature.
You can verify the configuration of this threshold by running the Exec mode show threshold command.
Save the configuration as described in the Verifying and Saving Your Configuration chapter.
Checkpointing Logs
Checkpointing identifies logged data as previously viewed or marked. Checkpointing allows you to only
display log information since the last checkpoint.
Individual logs may have up to 50,000 events in the active log. Checkpointing the logs results in at most
50,000 events being in the inactive log files. This gives a maximum of 100,000 events in total which are
available for each facility logged.
You check point log data via the Exec mode logs checkpoint command to set the log contents to a well-known
point prior to special activities taking place. This command may also be a part of periodic regular maintenance
to manage log data.
Checkpointing logs moves the current log data to the inactive logs. Only the most recently check pointed data
is retained in the inactive logs. A subsequent check pointing of the logs results in the prior check pointed
inactive log data being cleared and replaced with the newly check pointed data. Checkpointed log data is not
available for viewing.

Saving Log Files

Log files can be saved to a file in a local or remote location specified by a URL. Use the following Exec mode
command to save log files:
save logs { url } [ active ] ] [ inactive ] [ callid call_id ] [event-verbosity evt_verboseness ] [ facility
facility ] [level severity_level ] [ pdu-data pdu_format ] [ pdu-verbosity pdu_verboseness ] [ since
from_date_time [ until to_date_time ] ] [ | { grep grep_options | more } ]
For detailed information on the save logs command, see the Exec Mode Commands chapter in the Command
Line Interface Reference.

is 90%. If lower_percent is not specified, the default clear value is upper_percent.
seconds (5 minutes).
Checkpointing logs should be done periodically to prevent the log files becoming full. Logs which have
50,000 events logged will discard the oldest events first as new events are logged.
An Inspector-level administrative user cannot execute this command.
