Horizontal discovery is working fine.But when I run the Service mapping discovery by providing the management IP it is giving the following error:
Permission issues: SSH authentication failed. Verify that credentials have been correctly define for host 1X.XXX.XXX.XX. SSH authentication failed on host 1X.XXX.XXX.XXX. Failed to initialize SSH connection to host. Verify that the host can be access through SSH.
Why do we need SSH credentials for for load balancers ?
Why It is not able to discover even though SNMP port 161 is open ?

@marlos, my networking team gave me read-only SNMP access to our F5 LTM appliance and will not give me SSH access without justifiable reason. By chance, do you know what information is available when using SSH that is not available via SNMP? I can't seem to find anything in the documentation that states what information is extracted from each protocol.

SSH credential for F5 LTM would usually be required so we can issue tmsh commands for Service Mapping:

Since you have the F5 already Discovered through the horizontal / snmp probe & sensor, the question comes to mind: why can't ServiceMapping read the management IP off the F5 from the CMDB after matching a Load Balancer Service with the entry point?

Hi Johnny,
Since the entry point IP resolves to actually a host that provides the service, it's transparent to ServiceNow how does a given IP resolves to point to that host. The way ServiceNow is able to figure that out is through the management IP. Through it ServiceNow will now know that it can attempt to ask to a load balancer how the given entry point will be resolved.
This is the reason why the management IP needs to be defined.
Thanks,
Berny
