Zabbix says apache or mysql is not running

[fabWeb]

Zabbix-agent is ok on the host, and mysql and apache online but Zabbix-server says apache or mysql is not running

I change “proc.num[httpd]” to “proc.num[apache2]“ into item but nothing...

Any ideas please ?

Hi all,
I have the same issue on a debian squeeze...
I don't understand why...
Did you find how to solve this problem?

not really...

lookup up to zabbix page http://www.zabbix.com/documentation/...l/config/items :

Linux-specific note. Zabbix agent must have read-only access to filesystem /proc. Kernel patches from www.grsecurity.org limit access rights of non-privileged users.

I have the same problem on two Debian squeeze (6.0.5) servers: Zabbix says apache, mysql, inedtd, syslogd, sshd are not running on the servers...
grsecurity kernel patch is not installed.

Any idea?
thank you in advance...

Okay. I found the reason for message about Apache.

Solution:
Just go to Configuration -> Templates, then to Template Linux & Items.
Change for Item "Number of running processes apache" in the key httpd to apache2 (so new value is proc.num[apache2]).

Reason:
In Debian/Ubuntu the process for apache instance is named apache2.
I guess the same fixes are required for others keys when processes are named differently in different OS (Debian, Ubunty, CentOs...).

Thank you very much, very helpful and probably you are right, but the problem is still there...
I have Zabbix 1.8.2, so I do not have Configuration -> Templates menu.
I used the Import/Export menu under "configuration" to export the Linux template, make the correction and then re-import it.
I edited the line about Apache this way:

<expression>{Template_Linuxroc.num[apache2].last(0)}&lt;1</expression>

but the re-import of the corrected .xml file fails, with this error:

No such monitored parameter (proc.num[apache2]) for host (Template_Linux)
Trigger [Apache is not running on {HOSTNAME} ]: cannot create

Searching in this forum I found that a solution maybe to edit /etc/zabbix/zabbix_agentd.conf and add a user-defined monitored parameter, but, if so, I can't find the right syntax...
