There are several DPM testing tools and a suite of DPM nagios plugins (see the monitoring docs) but these utilise NRPE and are relatively complex compared the the quick and useful DPM-Tester.py
This is a script that wraps that test tool for nagios; the original test script doesn’t exit with any exit codes, so it is grep’ing for the word fail and counting the number of lines, it is also checking to see if the script seg faults as it does randomly seg fault if a proxy isn’t set.
This assumes you have half a clue of what you’re doing and are running the script on the nagios host, a host certificate with the appropriate permissions in DPM and a passwordless key.
The latest version of this script can be found on github

# I would suggest reading this script and implementing your own version of it.
# Put your host certificate & key in /etc/nagios/ and 400 it to nagios.
# Add a Grid Map for this host certiciate to your DPM Test PATH on your DPM Server.
