Zabbix watchdog

[frater]

I've been running a simple but effective watchdog in Zabbix for quite a while and wanted it to share with all of you.
One shouldn't use this watchdog without any monitoring.
Of course it's Zabbix itself that monitors it....

The script:

grep cron.1min /etc/crontab

*   *   * * *   root    cd / && run-parts --report /etc/cron.1min

cat /etc/cron.1min/zabbix_watchdog

#!/bin/sh
netstat -lntp | grep -q zabbix_server && exit 0
sleep 5
netstat -lntp | grep -q zabbix_server && exit 0
/etc/init.d/zabbix-server start
exit 1

I'm monitoring /var/log/zabbix-server/zabbix_server.log for the text "Starting Zabbix Server"
I'm using my own item-function "regcount" for this...
Maybe we can get that function into Zabbix


[/var/log/zabbix-server/zabbix_server.log,"Starting Zabbix Server"].

Hi,

You're right in saying that Zabbix itself should be monitored but I think that, like you said, it's a bad idea to restart the server without trying to know why in the first place it stopped or crashed You may be hiding a more serious problem by doing this.

Regards.

I'm not hiding anything....
My Zabbix-server never crashes.
I had a version that did this a year ago.

If it ever does this again, I will see in Zabbix that the server restarted xx times in the last half hour... and I can start investigating.....

Just a matter of being prepared.
I will probably have changed something (new version) and can revert..
In the mean time Zabbix keeps running.
