used disk space , Processor load etc in percentage.

Hi

These are all documented under items in the manual.

The used disk space, Swap space, memory all are in numerals that is in KB. Hence i need to know the parameters that would be used to find in percentage. For eg:- i would like my trigger to send a mail only if the used disk space is more than 75%

Right now i am using parameters like
vfs.fs.size
vm.memory.size
vfs.fs.size
proc_num

All these parameters will give numerals as output I need it in percentage . How do we go about it?

For your sanity, there is no way to get processor load in percentage, that just doesn't make sense. You can get cpu percentages in zabbix, but not disk.

To get percentages for disk space, you have to make your own custom parameters. I don't have examples for you. You might find them in the forums, or just get creative and come up with some.

I do agree though, zabbix should have disk space in %. For cpu %, try cpu_util and system.cpu.util. I just grabbed that from the docs.

Ugh... where did they go?!

Disk percentage use to be in Zabbix.

mode "pfree"

ex: vfs.fs.size[/,pfree]

Hi

I have modified my trigger to be like this:
({Host.Unix:vfs.fs.size[/,free].last(0)}/{Host.Unix:vfs.fs.size[/,total].last(0)})*100<20

This trigger throws an alert when the Free disk space is below 20%.

The other way to find the Disk space in percentage is by using user parameter with the shell command
df -k / /var /export/home|awk '{print $5,$6}'

Thanks a lot to all

Here is what I did to over come those obsicles. I have several servers with several TB's. Seeing a terabyte in Kb just plain hurt my eyes. I know my servers well enough that percentage is just plain fine. So here's what I did to get Disk space percentages in linux and bsd.

myservername# df -h
Filesystem                                                Size    Used   Avail Capacity  Mounted on
/dev/ad8s1a                                               496M     55M    401M    12%    /
devfs                                                     1.0K    1.0K      0B   100%    /dev
/dev/ad8s1e                                               3.9G    323M    3.2G     9%    /tmp
/dev/ad8s1f                                                57G     27G     25G    51%    /usr
/dev/ad8s1d                                               1.9G    504M    1.3G    28%    /var

As we all know a simple df -h gives us the above result. Within linux you can chop this up into pieces by rows and columns using "awk" & "sed".

So basicly here's one of my custom user parameters.

UserParameter=hdpercent[root],df -h | awk '{print $5}' | sed -ne 2p | cut -d"%" -f1

awk '{print $5}'
This tells it, from the uppermost left corner of the df -h result to go over 5 columns. Which gives us the "Capacity column".

sed -ne 2p
tells it from the top to move down two rows.

Which gives us 12%, the percentage of used space on my root partition. at the end I have it chop off the % sign with the cut -d"%" -f1

And that is how I got disk percentages in linux and bsd

i've been using this command for monitoring disk free space: (Similar)

basicly:
greps for any line which ends in /path/to/directory regardless of case (-i)
grab the fourth column
and cut the % off at the end so we're left with only a number.

df -h | grep -i /path/to/directory$ | awk '{print $4}' | cut -d"%" -f1

it will either be that or:

df -h | grep -i /path/to/directory$ | awk '{print $5}' | cut -d"%" -f1

depending on how your system is set up.

so try em both
