We are running Apache 2.2 on our Web servers. My Web Developer wants to know what all can SAM do for Apache? What all does it monitor?
You can monitor URL's, Web Ports (80, 8080, 443, etc), Apache processes, and Apache statistics. There is an Apache Tomcat template that I found HERE in the forums that you can take a look at. You also have the ability to write your own script monitors that will SSH into the box and pull data back.
I hope this helps!
For Apache I have enabled Mod_Status on the apache server.
That exposes a whole bunch of really useful stats from the server and is pretty simple to configure
As a warning though, make sure to lock down the access to the status page on the server so that you are not releasing the status page to the internet
We restrict it to localhost and the SAM server.
Check out the apache doc and one of the Apache monitor templates
The other option is to use the Mod-Apache_SNMP module, although the module itself hasn't seen any updates since 2006 so your mileage may vary!
