THOLD - Disk Percentage calculations

[redawg]

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

Here are the files in the zip with readme as to where they go. Hope it helps trying the other way was annoying the crap out of me.

Thanks for the files.

when you say import this file using the cacti interface? You mean the website right? also where in the website?

thanks.

[jrego]

and then what after i do that? do i need to make any additional changes? or will there be an option now for %?

thanks for your help.

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

[juge]

It works perfectly for me on 0.8.7b.

thank redawg !

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

[redawg]

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.

[kroyer22]

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 with me.

Thanks anyway.

[mlum]

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.

[caoboth]

I had the same issue however ive since resovled it, check the graph templates have imported correctly, as i noticed that they dont create the extra hdd_percentage variable, (this is in the Host MID available disk space) trace this back through the data sources and make sure that SNMP - Get Mounted Partitions also have the hdd_percentage variable.

Cheers

Andy
P.s this was on 0.8.7b on sles 10 sp1

[gheppner]

Same issue - FIXED . Here's how:

Go to Data Queries --> ucd 10fs --> "Available Disk Space" link (under Associated Graph Templates)

You'll notice that Data Source: hdd_percent is set to hrStorageSize (Total Size). Use the drop down to select hrStoragePercent (Percentage Used). That fixed it for me.
