Plug-In Tutorials

It looks like nobody mentioned when they uploaded their plugins that you you need mod status enabled to read the information from apache, one of the plugins says this and I was able to get check_apachestatus.pl working with Nagios now.

Check out this link:

http://httpd.apache.org/docs/2.2/mod/mod_status.html

You will need to edit /etc/httpd/conf/httpd.conf and add the following line to the bottom:

Code: Select all

<Location /server-status>
SetHandler server-status

#Order Deny,Allow
#Deny from all
#Allow from .example.com
</Location> 

And then search for ExtendedStatus and un-comment its line so that it is set to on.

If you are using VI or VIM to edit, you can use the "/" followed by the text you need to search for and hit enter. This will take you to the line it is located on.

Ah that's very good to know! Thank You.

I added that section to the bottom of my file. However, I have no ExtendedStatus text in my config file.

you likely can add the following just above the other info you added to the file

Code: Select all

ExtendedStatus On

then

Code: Select all

service httpd restart

You should be able to view some information in your browser at

Code: Select all

http://<YOUR_IP>/server-status?auto

[A.Cormack]

It doesn't appear to like the command. If i restart it with just the <Location......> then it restarts. But if i add

Code: Select all

ExtendedStatus On

Then it fails to restart.

What does it tell you when it fails to restart? It should give you some sort of configuration error.

[A.Cormack]

It just says...

Code: Select all

The requested operation has failed

I checked the error log file of the log directory but there was no errors in there.

Im running Apache2.2 on Windows Server 2008

[A.Cormack]

Ah ok, So i checked the EventView in windows (Should of done that before)

It says

Code: Select all

>>> Invalid command 'ExtendedStatus' perhaps mispelled or defined by a module included in the server configuration 

[slansing]

Okay, didn't know we were doing this on a Windows system, we have been walking you through this thinking you were trying to first monitor your localhost, and then a linux apache server sorry for the confusion. I've looked at a couple examples of httpd.conf files on windows apache server's at it looks like ExtendedStatus should be able to be added like this.. right above where we added the handler:

Code: Select all

ExtendedStatus On
<Location /server-status>
SetHandler server-status
#Order Deny,Allow
#Deny from all
#Allow from .nimsoft.no
</Location>

[A.Cormack]

Sorry my appologies, I should have explained it better. I need to approach it in a fair approach, so first of all im trying it on a windows server and then ill be trying it on a Ubuntu.

Ok so I went into httpd.conf and the bottom of the file now looks like

Code: Select all

ExtendedStatus On
<Location /server-status>
SetHandler server-status
#Order Deny,Allow
#Deny from all
#Allow from .nimsoft.no
</Location>

But the error still occurs

[scottwilkerson]

not totally sure about on the windows system but you may also need to add the module, like

Code: Select all

LoadModule status_module modules/mod_status.so

Also, you will need to restart the windows service for apache

[A.Cormack]

Once I uncommend "LoadModule" line, then Apache successfully booted up.

However, when running the test command

Code: Select all

./check_apacherequests.pl

I still get the error message

Code: Select all

Argument "" isn't numeric in numeric ge (>=) at ./check_apacherequests.pl line 76.
OK -  current apache requests | 'apache requests'=;2;3
