UserParameter for zabbix_server?

[jack]

I need to use a 3rd party tool to monitor a special service. I can get by setting UserParameter in each agent, but that requires me to install this 3rd party tool on every server that is being monitored which is a big pain!

Is it possible to have something like UserParameter that I can use for zabbix_server?

[jack]

Wouldn't this put all the collected data under the 1 server? I'm trying to have the data recorded under their respective machine.

ZABBIX v1.1 will possibly introduce 'external checks' , i.e. checks executed on ZABBIX server, kind of server-side UserParameters.

[jpawlowski]

this would be great!

however I would also like to have the UserParameter in the agent to support variable parameters for the executed command.

It is already supported! Define your parameter as (for example):

UserParameter=test[*], echo

Then you may add items test[1], test[5], test[hello], etc. The '1', '5' and 'hello' will be passed to 'echo' as command line parameter.

The following command will be executed:

echo 1
echo 5
echo hello

GREAT!!! thnx :-)

so until the external checks are directly supported by the server, I just create userparameters for the agent on the zabbix-server itself.

Btw: I had to modify the structure of mysql-table "items": field "key_" max length of 64 is not enough as I would like to be the parameter a URL. so i altered table with 'key_'=VARCHAR(128)

Can I access the key parameter (e.g. 1, 5, hello) through a variable?

Problem with UserParameter

Hi,

I want to Monitor the amount of used disk space in percent with zabbix and wrote a little perl script to do so. The script itself is working, but if I try to use it with zabbix by invoking the following key:

capacity[/]

and this User Parameter:
UserParameter=capacity[*],/usr/local/zabbix/bin/zsizeof.pl -f

I get in the shell on which the zabbix_agentd has been started the following error message:

sh: /: cannot execute

I use zabbix 1.0 on Solaris 10

Regards,
Frank.

Did you check:

She-Bang Line?
Permissions?
eXecute Flag?

The following command will be executed:

echo 1

I, write a litle script to count the process runing for specific command and add the following line to the agentd config file:

UserParameter=WorkingProcess[*],/home/zabbix/scripts/working_process.sh

I probe the script with this:

[root@router zabbix]# /home/zabbix/scripts/working_process.sh mysqld
0

Next add the item:

WorkingProcess[mysqld]

But i receive this message on the onsole:

sh: line 1: mysqld: command not found

I have instaled zabbix 1.0

Can you help me?

Thanks

It looks like your script is trying to invoke mysqld? You will probably need to specify its full path, or setup the path environment variable yourself.

thanks Jack for your qickly responce, but the script only count the number of process runing and the parameter is only used for a regexp search, this is the code of the script:

#!/bin/bash

#Usage:
# working_process.sh daemonname
#

ps axr -o %c | grep ^$1\$ -c

And i probe the that script run under the user zabbix without problems.

I am running on Linux Redhat Enterprice 3.

Thanks!

Did you try using full paths to ps and grep?

[andresherrera]

bug or a feature that is not supported

Hi, and thanks again for your answer.

Today i have tried with many changes on the UserParameter with the same errors.

I try with the Alexi's example:

It is already supported! Define your parameter as (for example):

UserParameter=test[*], echo

Then you may add items test[1], test[5], test[hello], etc. The '1', '5' and 'hello' will be passed to 'echo' as command line parameter.

The following command will be executed:

echo 1
echo 5
echo hello

The result is the same, but now the error on the console are:

sh: line 1: 1: command not found

Then i tested this item:

test[echo 2]

The result was succesful, the system send back "2" as a result!

Then i think this is a bug or a feature that is not supported on my version of zabbix 1.0.

I read for many minutes the source code of the agent and found that my thoughs are correct:

UserParameter=myparam[*],/any/command
with the item: myparam[myrealcommand]
Result on execution of
"myrealcommand"
instead of
"/any/command myrealcommand"

For now, i'll create items with this "bug", but i think that must be changed on the new versions.

Thanks!
