Agent communication failure

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:
  1. See if your machine is connected to the network. If yes, check for intermittent connection as well.
    Windows: Learn how to check connectivity to Site24x7.
    Linux: Learn how to check connectivity to Site24x7.
  2. 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.
  3. 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: /etc/init.d/site24x7monagent status
    FreeBSD: Execute the following command: /etc/rc.d/site24x7monagent status
  4. Ensure the disk partition where the agent is installed has enough storage space.
