Discovery probes and classifiers for IBM mainframes.

[Jourdan Rothsc1]

i'm new to servicenow and our environment include couple of IBM mainframes, we are trying to discover them using the snmp protocol and default probes and never successful, every time i run the discovery it gives me "active and couldn't classify ", can someone let me know the best process to discover mainframe if there is any out of the box discovery process available or any custom built discovery probes and classifiers for IBM mainframes.

Hi Jourdan

There is an out of the box probe for z/OS in London.

https://docs.servicenow.com/bundle/london-it-operations-management/page/product/discovery/concept/zOS-discovery.html

It doesn't seem to collect too much about the mainframe - but at least there is something.

I haven't yet had the chance to use it myself - so cannot comment on how well it works

Regards

Martin

Hi -- The message "active and couldn't classify " tells you that the IP responded and the port, very likely #22 for SSH, was open... and then Discovery tryed to login (again probably via SSH).   Be sure your credentials are set correctly.   This error is most often lack of permissions (credentials)

Test your creds by going to a terminal/putty session/similar are try to SSH to the IP of the mainframe.  Also test your credentials in Discovery>credentials.   Verify access is setup and then try to re-run disco...

Hope this helps?

Dave,

Thanks for the response , being trying to discover the IBM Mainframe with SNMP and unsuccessful to-date, is SSH the only way to fully discover the IBM mainframes or is there a way via SNMP to configure.

Thanks

Hi -- Sorry I didnt look at the MF probe before replying.  Its either SNMP or SSH, but either way the point is the same... the creds must be working to get past 1st base...  The error mentioned is most often credentials problem, so focus on that (IMHO)... for either SNMP or SSH... which is used.  

Hope this helps?
