Understanding MongoDB Error Code - 254

MongoDB Error Code - 254, also known as FreeMonHttpTemporaryFailure, occurs when the MongoDB monitoring agent (MMS) fails to connect to the MongoDB server. This error is usually related to network connectivity issues or problems with the MMS agent itself.

Possible Causes of MongoDB Error Code - 254

There are several potential causes for this error:

  • Network Connectivity Issues: The MMS agent may not be able to establish a connection with the MongoDB server due to network problems. This can include firewall restrictions, DNS resolution issues, or network configuration problems.
  • MMS Agent Configuration: Incorrect configuration of the MMS agent can lead to this error. It is essential to ensure that the agent is properly configured with the correct MongoDB server details.
  • MongoDB Server Issues: The MongoDB server itself may be experiencing problems, such as high load, insufficient resources, or other issues that prevent the MMS agent from connecting.

Fixing MongoDB Error Code - 254

To resolve MongoDB Error Code - 254, follow these steps:

Step 1: Check Network Connectivity

Ensure that there are no network connectivity issues between the MMS agent and the MongoDB server. Check for firewall restrictions, DNS resolution problems, or any other network-related problems that may be preventing the connection.

Step 2: Verify MMS Agent Configuration

Double-check the configuration of the MMS agent to ensure that it is correctly set up with the appropriate MongoDB server details. Make sure that the agent is pointing to the correct server address, port, and authentication credentials.

Step 3: Restart MMS Agent

If the MMS agent is running but still encountering the error, try restarting the agent. Sometimes, a simple restart can resolve temporary issues or conflicts that may be causing the error.

Step 4: Check MongoDB Server Status

Verify the status of the MongoDB server. Ensure that it is running correctly and has sufficient resources to handle connections from the MMS agent. Check the MongoDB logs for any error messages or warnings that may indicate server-side issues.

Step 5: Update MongoDB and MMS Agent

Ensure that you are using the latest versions of MongoDB and the MMS agent. Upgrading to the latest releases can often resolve known issues and improve compatibility between the components.
