Issue/Introduction

The SystemEDGE agent stops responding to SNMP requests after pushing a new VAIM policy with extension monitors.

Cause

Invalid\problematic extension scripts are causing the agent to hang during policy validation.

Environment

Release : 12.9

Component : VPM GENERAL

Resolution

• When a policy is deployed to a SystemEDGE host from VAIM the sysedge.cf file is delivered to the port#/temp directory.
• Once the the sysedge.cf file is validated it will be moved into the port# folder.
• During the validation process SystemEDGE will attempt to run all extension scripts included in the configuration to make sure they returning the expected result.
• Enabling debug on the SystemEDGE host you can see what monitor the agent validation is hanging on and take the appropriate corrective action.
