Unable to get HostMonitor (SystemEdge) to install properly on Windows 2012 Server

Products

• CA Application Performance Management SaaS

Issue/Introduction

The Infrastructure Agent with the HostMonitor appears to install properly but we are not getting the proper SystemEdge metrics. 

InfrastructureAgent Release 21.1.0.25 (Build 990025) on Windows Server 2012 R2

Here is what it reports in the Investigator for SystemEdge:

The IntroscopeAgent.log is showing following errors.

[WARN] [IntroscopeAgent.SnmpCollector] Received a null response PDU for SNMP GET for HostName OID 1.3.6.1.2.1.1.5.0
[ERROR] [IntroscopeAgent.SnmpCollector] SNMP Agent is not responding, check if CA SystemEDGE or alternate agent is up and running!

Environment

Release : SAAS

Component : APMAGT

Resolution

There was a very old standalone version of SystemEdge installed on the server.  

Uninstalled the older version and then reinstalled the APMIA with the Hostmonitor.

After this the APMIA agent started reporting the proper SystemEdge metrics.
