yaap (yet another apache plugin)

04-02-2011, 23:03

I didn't like the other apache plugins, so I took my ASSP plugin and rewrote it to cater Apache.
I just got it working so it may need some tinkering. Because it was a rewrite of another plugin it may contain some code that could look awkward....

apache2zabbix -x
will create an XML-file if you have Apache listening on localhost.
apache2zabbix
will send data collected from Apache at localhost:80
apache2zabbix -v
verbose output
apache2zabbix -f file
can crawl several websites and send it (format: hostname host port )

It also works for lighttpd as I just found out. I added a little line to translate "servers" into "workers"....
Now I can also monitor my Western Digital Worldbook's webserver for which I don't have an agent......

cd /etc/cron.min
ln -s /usr/local/sbin/apache2zabbix
cat /usr/local/sbin/apache2zabbix

Code:

#!/bin/sh
export PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin

sender="zabbix_sender"
sender_version=`${sender} -V 2>/dev/null | head -n1 | awk '{print $3}' | grep -o '[0-9]*\.' | head -n2 | tr -cd '0-9'`

Updated your script

I've updated your script to make it a bit more flexible.

I added a few lines to the -? option to describe the hostfile format and a crontab entry.

I added the following option:

-s to specify either lighttpd or apache as the server

The xml generation now will be specific for either lighttpd or apache

I fixed a bug where if you had multiple servers in the zabbix_agentd.conf, it would not work, now it will upload to all servers listed in the file.

I wasn't able to include the code, so I've uploaded it as an attachment
