System Monitoring
To do this:
View the number and status of physical ports on each line card. Output indicates Link
and Operation state for all interfaces – Up or Down.
Verify CPU usage and memory.
System Status and Performance
Check a summary of CPU state and load, memory and CPU usage.
Check NPU utilization within the chassis.
Check availability of resources for sessions.
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).
