I think it's my server, quite possibly I screwed up something during
the initial setup two years ago or along the way updating it from 5.0
and so forth until it's not behaving in any recognizable manner
anymore.

It looks good and I decided to give it a try in hope that maybe it can
be up and running faster than I can get MRTG to work again.
Unfortunately, as above mentioned, my server does not behave like a
CentOS server anymore. Following the steps at OpenNMS, I get to the
install -dis stage where it promptly dies because it cannot find jrrd.
downloaded jrrd but it refuses to ./configure because it cannot find rrd_create
yum install rrdtool but there was no rrd_create
searched online and the only result that was similar... was somebody
having the same problem on a Solaris server <-- hence making me wonder
if I was logging into the wrong server. Using the instructions there
however, I at least learnt how to tell configure where rrdtool was...
but it still cannot find rrd_create for the ./configure process
Having spent almost 5 days on this, I'm officially giving up on
monitoring the server with these tools. Writing a PHP script seems a
lot faster, I've already gotten a basic script running to pull load
figures from exec'ing uptime and emailing warnings if the load figures
stay above a certain level.
Now I just have to expand the script to exec snmpget for the other
metrices I need to keep track of. It's really frustrating that I have
to resort to writing my own code when these things worked fine for
other people.
