Hmmm...no, I didn't restart all the gmonds...are you saying I have to do this just on the gmetad/webfrontend box, the new data_source in question, or all 3000 of my nodes? I'll work on this and see how it goes.
The new data_source shows up just fine...the only thing that seems to break is the overview graph...and only the one for memory...the CPU graph seems fine. I'll try restarting my gmonds and report back. Thanks!

Hi Steve: Just curious - when you add in the new data_source, what steps did you take to restart the daemons? Usually I have to stop all the gmond daemons, stop gmetad, then start gmond and gmetad. Seems quite sensitive about the steps taken to restart the daemons. Also, when you add the new data_source, do they show up as a separate data_source in the main page? Are they listening on separate ports? Cheers, Bernard Steve Gilbert wrote: > My problems keep getting worse.
