Unable to populate devices in service mapping

[Venkatesh Janag]

A Calculated application service type application is unable to populate devices in service map. when we hit with URL provided it is not going bring the devices available for that application in infrastructure. what is the issue?

If it is due to credentials or capabilities related issue, what's the solution? 

how can I check ports are opened for the particular host, and credentials are valid or working for particular instance?

Please suggest me best solution with steps to resolve the issue.

Hi @Venkatesh Janag ,

If a Calculated Application Service is not populating devices
verify
 

• Ensure the entry point URL is correct and reachable from the MID Server.

• Verify the required credentials using Test Credentials or Connection & Credential Alias Test.

• Check the Discovery Status and Pattern Debug to identify any discovery or pattern failures.

• Confirm the MID Server has the required capabilities and is Up and Validated.

• Verify the target host is reachable from the MID Server and that the required ports (HTTP/HTTPS, SSH, WMI, SNMP, etc.) are open for the target technology.

• Review the ECC Queue for connection or authentication errors.

To verify connectivity from the MID Server host, use tools such as Test-NetConnection (Windows), telnet, or nc (Linux) to confirm the required ports are open.

 the first steps are to validate connectivity, credentials, MID Server capabilities, and review the Discovery Status and Pattern Debug before troubleshooting the application service configuration.

A Calculated application service will calculate its svc_ci_assoc configuration based upon that on cmdb_rel_ci. Calculated services do not launch patterns, probes - they simply work based upon what is in the CMDB.
