z/OS discovery

Discovery finds computers running the z/OS operating system.

Warning: DO NOT switch from probes to patterns if you are already running Discovery with probes, and your CMDB is already populated. If you do so, it is possible that the pattern Discovery process does not synchronize on the same values that the probe Discovery process does. This could result in duplicate CIs in your CMDB.


The USS service must be running on port 22 on z/OS.

These commands may be run on the host machine:
  • uname
  • hostname
  • sysvar SYSNAME
  • netstat
  • df
  • ls
  • cat
  • grep
  • ps
  • cut


Create SSH credentials.The user must have permission to write to /tmp, have read access to all user processes, and be able to run REXX scripts.
