Monitoring CPU & Memory in IOS-XE

ios-xe_cpu

One important thing to understanding in IOS-XE is the different numbers that can be returned when checking CPU and memory statistics.  There’s some very down in the weeds docs on this, but the simplest way to break it down is process vs. platform.  Processes is essentially control plane, while platform is data plane.

CPU

Processor CPU

CLI command: show processes cpu

SNMP OIDs:

1.3.6.1.4.1.9.2.1.56.0 = 5 second
1.3.6.1.4.1.9.2.1.57.0 = 1 minute
1.3.6.1.4.1.9.2.1.58.0 = 5 minute

Platform CPU

CLI command: show processes cpu platform

SNMP OIDs:

1.3.6.1.4.1.9.9.109.1.1.1.1.3.7 = 5 second
1.3.6.1.4.1.9.9.109.1.1.1.1.4.7 = 1 minute
1.3.6.1.4.1.9.9.109.1.1.1.1.5.7 = 5 minute

Note – Most platforms will be multi-core.

Memory

Processor Memory

CLI command: show processes memory

SNMP OIDs:

1.3.6.1.4.1.9.9.48.1.1.1.5.1 = Memory Used
1.3.6.1.4.1.9.9.48.1.1.1.6.1 = Memory Free

Platform Memory

CLI command: show platform resources

SNMP OIDs:

1.3.6.1.4.1.9.9.109.1.1.1.1.12.7 = Memory Used
1.3.6.1.4.1.9.9.109.1.1.1.1.13.7 = Memory Free
1.3.6.1.4.1.9.9.109.1.1.1.1.27.7 = Memory Committed
