We're in the process of switching from NSClient++ to NCPA since NSClient is depreciated, and I had a question regarding performance data. My new NCPA checks seem to be displaying the perfdata from the old NSClient checks, and not updating to the new NCPA format (CPU seems to be the same format so no worries there, only the Mem checks appear to be different in how they display graph data). I forget where the perfdata files are located, can you post the location for those so I can delete the old ones? If I delete the perfdata will the new checks just create new files then? And finally, I assume there's really no way to preserve the old check's perfdata since it's displayed in a slightly different format with NCPA, is that correct?

Example of what I'm talking about: Where the graph drops way down there is where we switched to NCPA. The perfdata is only showing data for 'available' when I would expect to also see 'free', 'total', and 'used', based on this being what is in the perfdata:

The location is
/usr/local/nagios/share/perfdata/<HOST>/<SERVICE>.rrd

Yes, if you delete the ond one, a new rrd will be created and display properly

You are correct, unfortunately there isn't a way to preserve the data for these 2 different plugins/agents as they do not match exactly

Ok, kind of what I figured but it never hurts to ask. And thanks, I'll write it down this time since I always forget where that dang directory is lol.
