# ocf-tester -n apache2 -o configfile=/etc/httpd/conf/httpd.conf 
/usr/lib/ocf/resource.d/heartbeat/apache
Beginning tests for /usr/lib/ocf/resource.d/heartbeat/apache...
* Your agent does not support the notify action (optional)
* Your agent does not support the demote action (optional)
* Your agent does not support the promote action (optional)
* Your agent does not support master/slave (optional)
* Your agent does not support the reload action (optional)
/usr/lib/ocf/resource.d/heartbeat/apache passed all tests
