[mod-security-users] Error: apache-monitor.pl

[Rudi S. <te...@wi...>]

Hi,

This email is with regard to the apache-monitor.pl found at 
http://www.apachesecurity.net.

I found the link via modsecurity.org and I believe the author is the same.

Sorry if this is off-topic and/or not apporpriate but I didn't know 
where else to ask.

I've installed the require perl modules and got the script to execute OK 
but there is no data.

First I kept getting this error:

./apache-monitor.pl /root/scripts/httpd/me 
http://xxx.xxxxxxx.xxx/server-status
Illegal division by zero at ./apache-monitor.pl line 170.

After I hacked the script a little I got it work but no data.
For example:

RRDupdate(/root/scripts/httpd/me.rrd)=1102232242:::::0:0:0::::::::::::
RRDupdate(/root/scripts/httpd/me.rrd)=1102232547:::::0:0:0::::::::::::
RRDupdate(/root/scripts/httpd/me.rrd)=1102232659:::::0:0:0::::::::::::
RRDupdate(/root/scripts/httpd/me.rrd)=1102232670:::::0:0:0::::::::::::
RRDupdate(/root/scripts/httpd/me.rrd)=1102232672:::::0:0:0::::::::::::

Seems like it's always ::::0:0:0:::::::

If you could help that would be awesome. These scripts look very useful, 
I'd like to use them.

Many thanks.
Regards,
Rudi

   Yep, that's me.

   You are right, the subject is slightly off-topic. Let's move to
   private communication after this.

   The script has very little error handling at the moment. After I add
   error handling (soon) I will make an official release.

   In my experiments the message above appears if you omit to append
   "?auto" to the URL. It should work properly if you execute it like
   this:

   ./apache-monitor.pl prefix http://www.apache.org/server-status/?auto

   Let me know if it doesn't work after this and I'll chase the problem
   for you. Otherwise use the current version until the official version
   is released (which will be accompanied by the proper documentation).

Bye,
Ivan
