hdd_used thold issue/questions

Post by temak82 »

Hello,

This problem has me stumped. I just upgraded to the latest 0.8.7d version of Cacti and 0.41 version of thold with 2.4 AP. Everything seems to be running well, but on a certain host, which runs Windows, I am unable to poll the C drive space, thus I am unable to get the notices if the drive is full. I have attached the zip file containing the images. I checked other Windows hosts being polled by the same cacti setup and they do work and show results. I believe I have also setup the hdd_used thold template correctly as well. If anyone has any tips on how to get this setup, please let me know. :)

Also, if anyone has any tips on how to setup a CDEF to monitor % used of either HD or RAM, please let me know. The hdd_used I have setup does not seem to be working correctly.

Thanks for anyone's help

1) Make sure you graph is working
2) You can not go over 100%, so 120% will never alarm.

Hi Witness,

Yep, I fixed the 120 already. Figure was in there before it was %, and I did not change it prior to taking the snapshots.

The graphs are polling now, took longer than the standard 10minutes. But looks like it is working, thanks.

I now have another question that was brought to my attention.

Attached is a zip with images of what I am talking about. In an nutshell, we have setup a bytes/s to Mbps CDEF and are using it to send alerts when Current Traffic goes above a certain Mbps figure for say 2 hours. This has worked like a charm on our old thold 3.9 and cacti 0.8.6j version. It seems to be working fine after the upgrade, however, when I go to the Treshold tab, it shows a few servers and under "Current" column, it shows random long numbers. Example: 10023.45. Can anyone let me know how these numbers are generated? If the high threshold is set to 3mbps, of course the alert will go off since 10023 is higher than 3. I checked the Data Source for Current traffic for that user and it was well below 1. So, a bunch of false-positives are being sent out to our users.

If anyone has any ideas, please let me know. Just check the images and you'll know exactly what I'm talking about.

Thanks again for your help

PM Cigamit on this one. I don't know how it handles counters.

Is there a way to perhaps downgrade back down to version 0.39? I see others have been asking this same question on this forum and cactiusers.org with no real answer from the developer.

Are you using 0.4.0 or 0.4.1 ? If it's the former, then there is a patch in the Threshold Plugin forum that enables CDEF support.

You might want to give it a whirl.

mcutting,

Thank you for the reply. Could you please give me a link to this? I did not find a threshold forum here. I am using 0.41.
