Error Message: The IP address is not in the discovery IP Range

Error Category: Probe Errors

Solution: Add the IP address or range to the Ranges setting of the probe. For more details, see Add an IP Range Manually.

Error Message: Inaccessible network path to target server. Perhaps it is a virtual IP address.

Error Message: The discovery job did not find any process listening on port: <port_number>

Error Category: Software Related Errors

Solution:

  • Check if the configured account has sufficient privileges to run relevant commands. Specifically,

    • ps -e
    • netstat -nap
    • lsof

    Elevate privilege for UNIX credentials.

  • Verify if the service is still accessible.
  • Check if lsof is installed on the target machine if it runs UNIX.
