[Check_mk (english)] can't monitor apache service

Archive checkmk-en

Hi all,

I am fairly new to this.

What I am trying to do: Monitor performance indicators of my Apache web
server

What I have done so far:

1. Installed the check_mk agent on the server checktest

gdebi check-mk-agent_1.6.0p5-1_all.deb

2. Installed the plugin apache_status to the agent on the server checktest

hsadmin@checktest:~$ cat /usr/lib/check_mk_agent/plugins/apache_status
...

3. enabled the module server-status

hsadmin@checktest:/etc/apache2/mods-enabled$ cat status.conf
<IfModule mod_status.c>
# Allow server status reports generated by mod_status,
# with the URL of http://servername/server-status
# Uncomment and change the "192.0.2.0/24" to allow access from other
hosts.

&lt;Location /server\-status&gt;
    SetHandler server\-status
    Require local
    \#Require ip 192\.0\.2\.0/24
&lt;/Location&gt;

\# Keep track of extended status information for each request
ExtendedStatus On

\# Determine if mod\_status displays the first 63 characters of a

request or
# the last 63, assuming the request itself is greater than 63 chars.
# Default: Off
#SeeRequestTail On

&lt;IfModule mod\_proxy\.c&gt;
    \# Show Proxy LoadBalancer status in mod\_status
    ProxyStatus On
&lt;/IfModule&gt;

</IfModule>

4. added a Python dict list for protocoll, servername and port

hsadmin@checktest:/etc/apache2/mods-enabled$ cat
/etc/check_mk/apache_status.cfg
dictList = [{'protocol':'tcp','servername':'checkmk','port':'80'}]

5. reloaded and restarted the apache service

77 systemctl reload apache2.service
78 systemctl restart apache2.service

6. run a bulk discovery on the checl_mk server via the web interface

The service apache_status won't show up in the monitoring.

What am I doing wrong? What am I missing? How to do it right?

Any cues, clues, tips is greatly aprechiated.

Best, David

Does Apache return anything when querying /server-status? Test with

curl http://127.0.0.1/server-status
curl http://[::1]/server-status
curl http://checkmk/server-status

With "checkmk" being the hostname from apache_status.cfg.

Hello,

Are you able to see Apache column while executing this command “cmk -IIv ”.

Thanks & Regards,
