Error: Check Status Failed

You can check the status of the agent / appliance on a computer from the Deep Security Manager console. On the Computers page, right-click the computer and click Actions > Check Status.

If you get a "Check Status Failed" error, open the error message to see a more detailed description.

If description indicates a protocol error, it's usually caused by a communication issue. There are a few possible causes:

Check whether the computer (or the policy assigned to the computer) is configured for agent-initiated communication or bidirectional communication. Unless you are using Deep Security as a Service, the "Check Status" operation will fail if you are using agent-initiated communication.
Check that the Deep Security Manager can communicate with the agent. The manager should be able to reach the agent. See Port numbers, URLs, and IP addresses.
Check the resources on the agent computer. Lack of memory, CPU, or disk space can cause this error.

If the description indicates a SQLITE_IOERR_WRITE[778]: disk I/O error, there is likely a problem with the agent computer. The most common problem is that the disk is full or write-protected.
