Disk space thresholds not working

I'm looking at the device graph for my disk and its showing 93% usage (its actually at 98% but linux has that 5% margin) and I'm not getting any events for this device. Looking at the OS tab, it seems to correctly report everything too. Any idea what I need to do to get some events generated?

    Re: Disk space thresholds not working
    What is the threshold set to for the filesystem template, and is it enabled?

    i have a threshold at 90% and 95%. both are set to enabled. 90% is a warning and 95% is an error.

    Re: Disk space thresholds not working

    ok so it appears that my thresholds aren't enabled, sort of. i have one named critical_disk_usage and one named high_disk_usage. They both pull from datapoint usedBlocks_usedBlocks and their max value is set to here.getTotalBlocks() * .95 and here.getTotalBlocks() * .9, respectively.

     

    When I click to view the thresholds, both have enabled set to false. So I try to enable both of them but only one of them successfully gets enabled. If I try to enable the other, the first one gets disabled. So I click out to some other page besides a template page and go back in there and now they're both set to False.

     

    This seems like some kind of bug or else some really screwy way of telling me I'm doing something wrong. Really not sure what to do now. Any ideas?

    Re: Disk space thresholds not working

    Ok, so just to make this more fun...

     

    When viewing Devices->Server->Templates->Filesystem, I decided to delete my critical threshold and after that, I was able to set the high threshold to true and it'd stay that way if I navigated to other pages!

     

    Then I go to Devices->Server->Linux->Filesystem and I see that the threshold here is now set to false. So now I set this one to true. (Btw, there appears to be a bug in the navigation here. The breadcrumb navigation up top reads /Devices/Server/Templates/Filesystem instead of /Devices/Server/Linux/Templates/Filesystem)

     

    After setting the value to true for the Linux template, I go back to Devices->Server->Templates->Filesystem and now this one is set to false. I can't seem to have my cake an eat it too

    Re: Disk space thresholds not working

    Try and copy your template down into the Linux portion of the tree.   then do the changes.

     

    What you are seeing is not a bug actually.  Everything in the server class is inheriting the values from that template, not just Linux.  Thats why it is above that device class.

    Re: Disk space thresholds not working
    Ok, that makes sense to me now. So I can navigate around it better now and creating the copy allowed me to set the /Devices/Server threshold to true. Unfortunately, I still can't set the /Devices/Server/Linux threshold to true. That one stays false as soon as navigate away from the filesystem template page. Any idea how to get that enabled?

    Re: Disk space thresholds not working
    Since it is now defined for class Linux, I would blow away both thresholds from the template, and do them both from scratch.

    Re: Disk space thresholds not working
    Ok, sorry. I spoke too soon. All that fixed was letting me create the thresholds. However, I'm still not getting any events about my disks being full. Just to be sure, the Max Value text box should have this value: "here.getTotalBlocks() * .9"

    Re: Disk space thresholds not working

    Here is what I have in my threshold for usedBlocks_usedBlocks:

    (here.totalBlocks * here.zFileSystemSizeOffset) * .95

     

    This is for version 2.4.1

    Re: Disk space thresholds not working
    unfortunately, that didn't work for me =(. that caused this error to show up in my event list and ended up disabling that threshold:
    User-supplied Python expression ((here.totalBlocks * here.zFileSystemSizeOffset) * .9) for maximum value caused error: ['usedBlo

    actually, I changed it back to what it was before and i'm still getting that same error...

    Re: Disk space thresholds not working

    What version of Zenoss are you running?  I can throw up an installation in a VM to see if I can duplicate it..

    Currently I use 2.4.1 at work, and 2.5 beta unpached at home, as well as one of the official Zenoss VM's to break things on.

    Sweet, that'd be awesome. I'm using 2.4.5.
