You can check the status of the agent on a computer from the Server & Workload Protection 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.
  • Check that Server & Workload Protection can communicate with the agent. See Port numbers.
  • 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.
