Unable to monitor CPU and Disk metrics for servers via SNMP in DX NetOps CA Performance Management (CAPM)

Products

• CA Performance Management
• Network Observability

Issue/Introduction

After discovery of server devices via SNMP on port 161, they are reachable and appear in NetOps Portal, however, they're only showing 'availability' data

Why are these servers not showing any CPU, Disk or other metrics? 

Environment

DX NetOps CAPM currently supported releases.

Cause

Depending on what SNMP agent is running on the servers, it will provide what MIB data is or is not supported and can be collected by CAPM. If the relevant OIDs are not in the agent MIB, then CAPM is not going to collect and show the data in dashboards. 

Resolution

An SNMP agent should be running and responsive on the servers to collect and monitor the specific CPU and Disk data.

Ensure the standard SNMP agent (net-SNMP on Linux OS, default SNMP agent on Windows OS), or the CA SystemEdge agent is running and functioning correctly on the servers being monitored.
