check_apache2.sh

It works good if you make changes as suggested in other reviews. If you have errors like the ones which daviduco has, remember that ExtendedStatus has to be set to On. I have always cpu load to 0, I think because it works only on localhost.

Along with the Array definition problem which davidak has pointed out on Aug 11, 2014, I found a question mark (?) missing in the php template file. After adding this question mark in PHP tag the pnp4nagios graph are populated. Changes required in check_apache2.php:- 1. Remove dot (.) from $opt[2] and $def[2] lines as mentioned by Davidak 2. Add question mark (?) to the php open tag at the beginning of file.

the template don't work. first it starts with "ine array indexes before adding content... change: $opt[2] .= "--vertical-label "Byte/sec " -l 0 -r --title "Apache metrics for $hostname / $servicedesc" "; $def[2] .= "DEF:bytepsec=$rrdfile:$DS[3]:AVERAGE " ; to: $opt[2] = "--vertical-label "Byte/sec " -l 0 -r --title "Apache metrics for $hostname / $servicedesc" "; $def[2] = "DEF:bytepsec=$rrdfile:$DS[3]:AVERAGE " ; please test code yourself before publishing it. except that the plugin works with Icinga 1.8.3

Hi geuse, Just edit the name_pid="apache2.pid" to "httpd.pid" ./check_apache2.sh -H localhost -P 80 -t 3 -wr 100 -cr 250 OK - Apache serves 19 Requests per second with an average CPU utilization of 53.8%. Busy workers: 71, idle: 20 | 'cpu_load'=53.8 'req_psec'=19 'bytes_psec'=125950 'bytes_preq'=9918.87 'workers_busy'=71 'workers_idle'=20

It works like a charm, only the pnp4nagios needs some little tweaking but if you're familiair with php it's piece of cake.

This is very good plug-in . Gathering server status but pnp4 template not working . Any idea please

Does not work well with IBMHttpServer. little change to trap process httpd instead of Apache2: cpu_load="$(cpu_load=0; ps -Ao pcpu,args | grep "$path_binary/httpd" But does not work... ./check_apache2.sh -H ...myServer... -b /opt/IBMHttpServer/bin/ -n httpd.pid OK - Apache serves 35 Requests per second with an average CPU utilization of 0%. Busy workers: 5, idle: 70 | 'cpu_load'=0 'req_psec'=35 'bytes_psec'=756659 'bytes_preq'=11031.4 'workers_busy'=5 'workers_idle'=70 The variable cpu_load seems does not change.

This is an excellent plug-in to get the Apache Stats.. You may need to modify the pnp template a bit to get it operational as I'm having strict variable declaration in my PHP..

Excellent script. Adding my contribution: A new template for PNP4Nagios, multigraph, with gradient colors and 4 graphs: 1) CPU Usage 2) Requests/Second 3) Bytes (per Second and per Request) 4) Workers (Idle and Busy) Works on PNP Version 0.6.14
