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. > And btw: OpenNMS might be overkill for your purpose, but you might want > to take a look: http://www.opennms.org. 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.
