ServiceMapping connection issue

[angel_jimenez]

Hi community!

When we launch Service Mapping, we are getting the following error:

<<Missing pattern-based outgoing connections from load balancer. Please check the correctness of the incoming connection>>

And the resulting map is the following: (see attachment map.jpg)

Checking the discovery log we see the following: (see attachment discovery_log.jpg)

Furthermore, checking for the step (Connecting section using CMDB data) we get to the following log:

How can we solve this issue? What does mean the error showed by ServiceMapping???

 Thanks!

It means that Service Mapping cant create the outgoing connections from the load balancer.

1. There should be a red step in the log, where it fails

2. Try opening the pattern in debug for the load balancer in question, and then go through the steps to see where it fails

Hi Michael!

Using the debug option, we have been able to identify that the problem was that we had no valid SSH credentials to run following commands in the A10 Load Balancer on top of the ServiceMapping:

1. "show config"
2. "show slb virtual-server | include " + $ip_address

Adding valid SSH credentials in "discovery_credentials" table in ServiceNow and running again ServiceMapping, we get the correct map.
