Can`t stop the agent

[isurugiu]

I am unsuccessfully trying to stop zabbix-agent

Even it won't quit after kill -9. Any hints?
This happens on multiple machines.

Perhaps, that init script is wrong.

What OS are using?
If you use Linux, what distridution and version are using?
What version are using of Zabbix?
Did you install any kind of procedure for Zabbix?

[isurugiu]

I'm using ubuntu 14.04.2 LTS x64 with

Zabbix Agent (daemon) v2.2.2 (revision 42525) (12 February 2014)

I can`t say that I have followed a certain procedure. I installed the packages via apt then added the client/custom configuration via chef.

I tried to install Zabbix agent to Ubuntu 14.04.2.
I used Zabbix SIA repository.
I can stop that agent by service command.
Of course, I can stop that agent by call init script.

Agent version:
Zabbix Agent (daemon) v2.2.9 (revision 52686) (12 March 2015)

I think that your init script is not match for Ubuntu 14.04.
Perhaps, that script is for old version of Ubuntu.
Plaese check your init script.

[isurugiu]

Thanks for your reply, but that does not help me very much.

Is it possible that teaching Chef recipes?
Perhaps I think incorrect init file is located in the recipe.

[isurugiu]

Zabbix-client is installed via apt by using a chef recipe. On the next step the configuration is replaced with a global one.

I am not sure what you want me to do. The init scripts were working fine until a few days ago. If you read my post from the top kill -PID or killall -9 zabbix_agentd is not working.

Do not that you can not stop with the init script?

[isurugiu]

I am not sure what you mean by that but yest I can't stop by either init script or kill.

[Colttt]

can you please post this init-script?

I try start and stop agent by your /etc/init.d/zabbix-agent.
I tried several times, but i was able to stop and start normally.
There was no problem in OS reboot.

But, there is a point that does not match the posted information.

When I started by this script, start-up option is not added to the zabbix_agentd.

root@ubt14:~# pstree -ahup | grep zab
  |                           |-grep,1689 --color=auto zab
  `-zabbix_agentd,1594,zabbix
      |-zabbix_agentd,1596
      |-zabbix_agentd,1597
      |-zabbix_agentd,1598
      |-zabbix_agentd,1599
      `-zabbix_agentd,1600
root@ubt14:~#

My environment don't have "-c /etc/zabbix/zabbix_agentd.conf" option.

It does not introduce a mechanism to start the agent automatically by using some other way?
ex. monit, upstart
