Ok so i was running ods and i noticed something peculiar. for all services with perfdata if they were related to a hostgroup ods tried to put all the perfdata from the services in that hostgroup in one graph.

so for instance if i related 5 different services as related to hostgroups
ods would merge all the data from those 5 services in one graph.

i ended up just relating each service to a per host type deal to separate the graphs and that worked fine but the preexisting graph that was merged still exists. Is there anyway to find out what rrd file and sql data that is and purge it?
