Possible reasons for an agent communication failure
When there is a failure in the agent communication, you will get a message,
"Agent service <name> could not establish communication with the Server. Please check if there is a problem with
the Network Communication. This could also happen if the Agent Service or the host itself is down."
In the above scenario, look for the following reasons and make sure your network communication is rectified:
Check for any change in the proxy configurations. If the username or password were updated in recent times, ensure they are updated in the agent.
Windows: Refer to this article.
Linux: Ensure the proxy is configured in the file
/opt/site24x7/monagent/conf/monagent.cfg under
PROXY_INFO section.
- Make sure the server and the agent service is up and running.
Windows: Go to services.msc > Site24x7 Windows Agent.Linux: Execute the following command: /opt/site24x7/monagent/bin/monagent status
FreeBSD: Execute the following command: /opt/site24x7/monagent/bin/monagent status
Ensure the disk partition where the agent is installed has enough storage space.
