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
