Version 2: Zabbix Template and PERL Script for Monitoring Apache2

Based on a recommendation at the Zabbix forums, we updated this Zabbix template and PERL script we are using to monitor our Apache2 server.

Here are the entries for zabbix_agentd.conf

Code:

UserParameter=apache2.total_accesses,cut -f1 -d":" /tmp/apache_data.txt
UserParameter=apache2.total_kbytes,cut -f2 -d":" /tmp/apache_data.txt
UserParameter=apache2.cpuload,cut -f3 -d":" /tmp/apache_data.txt
UserParameter=apache2.uptime,cut -f4 -d":" /tmp/apache_data.txt
UserParameter=apache2.reqpersec,cut -f5 -d":" /tmp/apache_data.txt
UserParameter=apache2.bytespersec,cut -f6 -d":" /tmp/apache_data.txt
UserParameter=apache2.bytesperreq,cut -f7 -d":" /tmp/apache_data.txt
UserParameter=apache2.busyworkers,cut -f8 -d":" /tmp/apache_data.txt
UserParameter=apache2.idleworkers,cut -f9 -d":" /tmp/apache_data.txt
UserParameter=apache2.totalworkers,cut -f10 -d":" /tmp/apache_data.txt

Basically, we have moved the PERL script to a crontab running every minute and we then write the results to a /tmp file. Then the Zabbix agent reads the data from the file instead of calling the PERL script 10 times. This is more efficient.

Also, we change the template to update every 60 seconds instead of 30 seconds to match the crontab entry.

Files attached. If you have any questions, please post here.

A2ENCONF(8)						      System Manager's Manual						       A2ENCONF(8)

NAME

       a2enconf, a2disconf - enable or disable an apache2 configuration file

SYNOPSIS

       a2enconf [ [-q|--quiet] configuration]

       a2disconf [ [-q|--quiet] configuration]

DESCRIPTION

       This manual page documents briefly the a2enconf and a2disconf commands.

       a2enconf  is  a	script	that enables the specified configuration file within the apache2 configuration.  It does this by creating symlinks
       within /etc/apache2/conf-enabled.  Likewise, a2disconf disables a specific configuration part by removing those symlinks.   It  is  not	an
       error to enable a configuration which is already enabled, or to disable one which is already disabled.

       Note  that many configuration file may have a dependency to specific modules.  Unlike module dependencies, these are not resolved automati-
       cally. Configuration fragments stored in the conf-available directory are considered non-essential or being installed and manged by reverse
       dependencies (e.g. web scripts).

OPTIONS

       -q, --quiet
	      Don't show informative messages.

       -m, --maintmode
	      Enables  the maintainer mode, that is the program invocation is effectuated automatically by a maintainer script. This switch should
	      not be used by end users.

       -p, --purge
	      When disabling a module, purge all traces of the module in the internal state data base.

EXIT STATUS

       a2enconf and a2disconf exit with status 0 if all configurations are processed successfully, 1 if errors occur, 2 if an invalid  option  was
       used.

EXAMPLES

	      a2enconf security
	      a2disconf charset

       Enables Apache security directives stored in the security configuration files, and disables the charset configuration.

FILES

       /etc/apache2/conf-available
	      Directory with files giving information on available configuration files.

       /etc/apache2/conf-enabled
	      Directory with links to the files in conf-available for enabled configuration files.
