Can't monitor process on the server

[thelan]

Hi everybody,

After installing Zabbix 1.6.4 on gentoo I can't monitor process running on the server.

This is realy strange because when I do :
Shell> zabbix_agentd -t proc.num[apache2]
proc.num[apache2] [u|11]

and when I query the serv using zabbix_get it returns 0
Shell> zabbix_get -s 127.0.0.1 -k proc.num[apache2]
0

But I don't have any probleme when I monitor the other hosts.

Thanks for your help.

Are you sure the process is called apache2?

What happens when you run the following?

ps -ax | grep apache2 | grep -v apache2 | wc -l

Some distributions use a different name for apache (apache, apache2, httpd).

[thelan]

grep apache2 | grep -v apache2
as -v is the option for invert-match :

-v, --invert-match
              Invert the sense of matching, to select non-matching lines.

I've run
Shell> ps ax | grep apache2 | wc -l
11

But i show an example with apache but it's the same with mysqld and others process like bash or anything else!

Hi Thelan,

did you find any solution to your problem?
I have exactly the same issue.

Thanks!

Did you try the solutions given?

Hi Nelsonab,

which solution are you talking about?

[thelan]

The probleme was (for me), that the server was running an GRsec patched kernel

As Zabbix was running with the zabbix user, it can't see the process form others

So i've recompiled the agent with the ALLOW_ROOT enable in the source code.

The other solution is to add zabbix user to an grsecurity exampted group.

Thanks for your help!

I enabled ALLOW_ROOT, i'm saved

GREAT!!!

You're welcome.

But it's discouraged to run Zabbix as root.
Consider adding the zabbix user the Grsecurity exampted group.
You can find the GID in your kernel configuration
