Forcing RRD file creation

Hello,

I just added the Check Ping zenpack and everything seemed to go well except for the graphing. I'm getting a "missing RRD file" on my graph.

I've restarted zenoss and checked /Perf/Devices and found no file corresponding to the device I added. Is there a way to force the RRD file into existence? Is there something else i should be checking?

I am still very early in my linux learning curve so please be gentle :-)

Thanks

    Hello stwainer,

    Welcome to the club.

    As near as I have been able to ascertain this is an issue in 2.4.x that did not exist in 2.3.x. You can go find my topic Missing RRD files for a list of trouble shooting steps or just do what I am about to link :)

    Basically you need to manually create that last rrd file. Thankfully it can be done with just a copy command :)

    ---------

    Well, after much digging I managed to get the graphs working. (at least I think... maybe)

    They are at least appearing to be working.

    I logged into /usr/local/zenoss/zenoss/perf/Devices/
    and into one of my devices.
    I then ran this command

    cp -b fping_max.rrd fping_min.rrd

    Right after that my graphs worked.

    So the new issue is why is Zenoss/fping Zenpack not creating this file when a new device/template is bonded? Anyone have an idea where the code that controls file creation for templates/ZenPacks might be located?

    Would you submit this as a bug/regression in their bugtraq?

    RE: Forcing RRD file creation
    Ill post here also, i solved the not updating/missing rrd problem by putting zSshConcurrentSessions = 1

    Hope this helps. This solves all problems for graphs where data type is command!

    Don't assume someone knows where you changed that setting.  I sure don't.  I didn't see it in zProperties.
