To monitor for Apache config file errors in Zabbix do the following:

1. Create monitor test script at /etc/zabbix/apache_configtest.pl with the following contents:

#!/usr/bin/perl

my $result = `/usr/sbin/apachectl configtest 2>&1`;
if ($result =~ /Syntax\ OK/ )  {
        print "0";
} else {
        print "1";
};

2. Add the following line to the end of /etc/zabbix/zabbix_agentd.conf:

UserParameter=apache.configtest,/etc/zabbix/apache_configtest.pl

3. From the Zabbix web interface add an Item for the new monitor at Configuration -> Items -> Create Item with the following settings:

Description: Apache config has errors

Other fields can be left at default.

4. Add a Trigger for the new Item at Configuration -> Triggers -> Create Trigger with the following settings:

Expression: {host:apache.configtest.last(0)}=1
Severity: Hight

Other fields can be left at default.
