Apache support in Jopr is very limited. You can autodiscover Apache servers and monitor whether they are up or down. To do the latter, you'll need to edit the Apache server Resource's connection properties under its Inventory>Connection tab and set the 'url' property to some URL that can be "pinged" to check if the Apache server is running (e.g. http://myhost.com/index.html).
To add support for collecting various request and response metrics, you'll need to purchase the JBoss Operations Network (JON) product, which includes the SNMP and Response-Time Apache modules. These modules cannot be included with Jopr, because they are not under an open-source license.
but we would love it is someone came along and implemented a more OSS friendly apache connector that we could use to manage apache with :)
integration with net-snmp or something of that sort
