Monitoring zabbix server itself

[woisch]

Hi,

sometimes i have a problem that the zabbix server seems to be running but do no monitoring job. If i restart the zabbix server all monitoring is good and mails send out.

How can i check if zabbix server is running well? I want a mail for example every 4 hours....

But if i configure a action for zabbix server agent this certainly didn`t work because zabbix server is than not running and send no mails....

Hope you understand what i mean.

Is there a solution / script for that?

thanks and regards

Hi,

i solved it by scheduling a shell script that checks the timestamp of the zabbix_server log file. If it is not modified in the last 10 minutes, then I assume there is something wrong:

#!/bin/sh
# check timestamp zabbix logfile, it should be modified in the past 10 minutes

RESULT='find /tmp/zabbix_server.log -mmin -10'
RESULT=$?

# if RESULT = 0 -> OK
# RESULT = 1 -> file not found

if [ $RESULT != 0 ]; then
/usr/local/bin/gnokii --sendsms xxxxxxxxxx "Zabbix $HOSTNAME not responding for 10 minutes"
fi

exit 0

I`m not the linux guru. I`ve tested the shell script with sending email. This works fine if i use the code on the console.

How can i setup the script now for checking every 10 minutes? I`ve stopped the zabbix-server and waiting for 10 minutes but i got no mail.

For scheduled checking, you should add the script to the cron:

edit the cron: crontab -e

then add a line like this:

*/5 * * * * /path-to-the-scripts/check_zabbix.sh


Now every 5 minutes the check will be executed.

Is the file on the given location /tmp/zabbix_server.log? Or do you have another log file location defined in the zabbix_server.conf?

Thanks for the answer.
No, the location is another but i`ve changed it in the script to /var/log/zabbix-server/zabbix_server.log .

The Problem is now as result i always got "0" if i try the command on the console:

zab-serv01:/bin# RESULT='find /var/log/zabbix-server/zabbix_server.log -mmin 5'
zab-serv01:/bin# RESULT=$?
zab-serv01:/bin# echo $RESULT
0
zab-serv01:#

If i look in the log file folder i saw that the last modified time is over 5 minutes for zabbix_server.log ?

Where is my problem?

[jlorier]

What is the output when you just execute the find command? Maybe it is just an permission issue.

[woisch]

zab-server01:/bin# find /var/log/zabbix-server/zabbix_server.log -mmin -5
zab-server01:/bin#

that`s it... what is the normal output?

[woisch]

If i try "+5" i got the following:

zab-serv01:/bin# find /var/log/zabbix-server/zabbix_server.log -mmin +5
/var/log/zabbix-server/zabbix_server.log
zab-serv01:/bin#

But as result still "0" ! Grmpf
