Symptom
- SNMP reported value for memory usage higher than expected
Environment
- PAN-OS
- Platforms with shared hardware
Cause
The SNMP OID polled is returning the global memory usage.
The CPU and memory are shared by the DP and MP, it is expected to see a high memory as the processes running on DP are running permanently.
Resolution
Review accordingly the threshold on the network monitoring system to take this behavior in account when the monitored platform is sharing MP and DP resources.
