Periodic Status Checks - Cisco ASR 5000 Installation Manual

System Monitoring
To do this:
Review session statistics, such as connects, rejects, hand-offs,
collected in 15-minute intervals.
View duration, statistics, and state for active call sessions.
Display statistics for the Session Manager.
Check the amount of time that the system has been operational
since the last downtime (maintenance or other). This confirms
that the system has not rebooted recently.
Verify the status of the configured NTP servers. Node time
should match the correct peer time with minimum jitter.
Check the current time of a chassis to compare network-wide
times for synchronisation or logging purposes. Ensure network
accounting and/or event records appear to have consistent
timestamps.
View both active and inactive system event logs.
Check SNMP trap information. The trap history displays up
to 400 time-stamped trap records that are stored in a buffer.
Through the output, you can observe any outstanding alarms
on the node and contact the relevant team for troubleshooting
or proceed with SGSN troubleshooting guidelines.
Check the crash log. Use this command to determine if any
software tasks have restarted on the system.
Check current alarms to verify system status
View system alarm statistics to gain an overall picture of the
system's alarm history.
If enabled, view statistics associated with Inter-Chassis Session
Recovery (ICSR).

Depending upon system usage and performance, you may want to perform these tasks more frequently than
recommended.
