It would be VERY nice to be able to specify percentages in thold. For example if I have 100 servers to setup it is annoying to have to specify exactly how full the hard disk needs to be on each one when they are different sizes. It would be so much simpler to say 90% on the template.

Actually, this is pointless to do in thold, instead, rewrite the hard drive script to also return a percentage. I did this 6 months ago and have been using it ever since without issues.

I'll post the script and XML files shortly.

Jimmy, any idea when this mod will be available for prime-time?

Here is the template, script, and a quick install instructions.



Let me know if you have any problems.

Also, just to note, this script also doesn't return the floppy, virtual memory, or the CDRoms (if they are empty).

I'm having a bit of a problem using this script with thold. The graph itself works great. I returns Total, Used and % Used info on all of my devices. When I setup a threshold to use it, however I get nothing. I create a new threshold template using "Host MIB - Hard Drive Space", "hdd_percent" and then set the high threshold to 80 and save it. I then assign this to one of my devices. I wait a while and look at the threshld tab and I can see the device/threshold, but in the "Current" column, it says 0. This happens on every device that I setup to use this template.

As a test, I setup a low threshold of 10 in the template just for kicks. I get the e-mail alert a few minutes later, even though the disk space is 40% on the particular device.

has anyone else seen this?

Thanks!

What about a threshold percentage for interface traffic? Is there any way to do this with Thold 0.3.0 ??

Thanks.

Currently no, since it only knows the value of the current datasource, not the one that you want to take a percentage off of. You could ofcourse modify the script and datasource to calculate the % and store it in the RRD, then you could easily threshold off of that.

Thanks Jimmy.

I saw here -> http://forums.cacti.net/about11360.html that you're currently working in Cacti 0.9.0 development.

Can you tell me if this new Cacti version will include Thold new functionalities (like the one I asked in my previous post - percentage thresholding for Interface Traffic)? And is there any estimate beta-version release date?

Thanks, congratulations for your great work, and good luck!

Has anyone been successful at setting up thresholds based on a percentage of drive space? My graphs show the percentage but I'm still having the same problems I mentioned in the post above.

Just wondering.....

Hi all,

Thks Jimmy for your great job!

but, i have a question :
when u say :

You will have to recreate the datasources for disk space on all your current hosts that use this,
Most importantly, this includes re-querying the "Associated Data Query" for the device!

it works fine with new graph, but does'nt update current ones.

do we have to delete rrd data and recreate a brand new graph?
is it possible to update current graphs with new percentage statistics? (if yes how?)

thks for all.

Phil.

Hi - I setup the latest thold and the host_disk graphs. Thold works correctly because it is alerting me on network interface usage. However, the host_disk does not seem to be returning data to the thold screens and in the database. The lastread field is blank in the database. Anybody have an idea why this would not be updating. See my attached screencaps. Thanks!

Does walking the OIDs manually return any results?

Yes - and the graphs for these data sources show the percent used. But the threshold part shows no data.

To fix the issue with thold not showing current drive % with this new template, I had to make a change within the Associated Graph Template for the SNMP - Get Mounted Partitions Data Query.

I had to change the Data Source hdd_percent from hrStorageSize to hrStorage Percent, and check the box next to it.

Here is a step by step.
1. Click Console
2. click Data Queries on the left
3. click SNMP - Get Mounted Partitions (is it misspelled in yours too?)
4. click "Available Disk Space" under Associated Graph Templates
5. change the dropdown for hdd_percent to "hrStoragePercent(Percent Used)
6. check the box just to the right of that dropdown
7. click save

and I'm not sure if this next step is necessary, but I did it anyway.
8. re-create the graphs.


Hope this works for you.
