THOLD - Disk Percentage calculations

Alright,

I have been struggling with this for awhile now, the CDEF fix works some of the time. but if you calc alot of they are very inconsistent..

So I took a patch from a couple people finagled around and edited it and have it working consistently.

Here are my files, working with cacti 8.7b

Remember 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!

After you install these files you will see this in you cacti.log

I have cacti verstion 0.8.7a and your graph template does not work on that. I created a graph template with disk but I dont see any percentage values. Are you doing anything different on this graph template? Can you please explain

Hi,

i don´t get the percentage displayed so far. Maybe first of all my system configuration:

Fedora 8

Apache/2.2.6
mySQL 5.0.45
PHP 5.2.6

Cacti 0.8.7b
Plugin Architecture 2.1
Settings 0.5
Thold 0.3.8

First of all i imported the template. After that i copied the two .xml files and overwrote the existing files. Then i added a new device (Windows XP SP2) and created a graph to display the disk usage. The max capacity and the used space are displayed correctly, but the percentage is only displayed as "nan".
In the readme file it is said to "recreate the database" and to "requerying the associated data query". How can i do this, or is it not important, because i added the new device after the modification?
I don´t realy know where to search for a mistake. Maybe somebody here has an idea.

bye

Re query the associated data source.. What I am refering to is going into the device and clicking on the circle to refresh the snmp data for disk space. if you want the source it will say

SNMP - Get Mounted Partitions (Verbose Query) Uptime Goes Backwards Success [32 Items, 8 Rows] Reload Data Query

if successful your items should be 3 time the amount of rows, previously it was 2 x the amount of rows because it was only doing max and used value.

I installed the Patch, Deleted all Graphs and re queried the data source. When I recreate a new graph I get NAN or 0% for the percent. Any thoughts?

Same problem for me. Tried all the steps above a few times but still 0 showing.

I'm assuming the percent figure is calculated in the amended ss_host_disk.php file? I wonder if it something to with the if statement order?

Anyone know PHP?

Not receiving the third "get percent" entry. hmmm. will keep looking.
