Hi,
java. I don't remember seeing this problem when installing from the opennms yum repository, though.
I didn't expect it either, honestly. In most cases, updates/installs does go relatively painlessly if I don't mess up following instructions/guides. In this case, I guess I just tripped up over the unessential jrrd.
Are you getting any benefit from mixing all of these non-stock versions on your system? How many different repositories that contain conflicting versions of packages do you use? Normally epel doesn't overwrite stock packages and opennms
I've no idea honestly, my primary role isn't server admin and I'm just winging it as I go along to support what I'm supposed to be doing with the server.
The PG 8.4 was because we're developing something for our client who's on that server, so I'm standardizing on 8.4 and likely will stick with it for quite a while, rather than going with the 8.3 since there appears to be quite a few changes in 8.4, especially on warm standby features.
Apart from what's needed, I usually try to avoid installing things on the public web servers we have.
That is normal - typically you'd run opennms on a machine dedicated to monitoring, with perhaps thousands of targets so it wouldn't be running a lot of other services.
Well, unfortunately, there's only that pair of machine in that particular location. I really needed the monitoring tool up on it because I've been noticing a higher than normal load since the weekend. My quick hack of a PHP/cat /proc/loadavg script was also alerting me consistently. After a couple of hours on opennms, it became obvious that something was hitting the server. Turns out that the client did not set the appropriate measures on their forum software and bots were having a field day hitting it to break the image recognition and finally got through to spamming.
Removing it won't bother opennms. It has an assortment of application probes that it uses in addition to snmp and is intended to work automatically with large numbers of targets - when it discovers a node (or you add it), it probes the application ports to see what is running, then periodically tests again and notifies you when something that was previously running stops working. However, it is very configurable and you can add/remove whatever you want.
Yup, it's pretty cool and that web interface really helps. While I am perfectly at home using a text editor, I really don't want to have to wade through and edit tons of text just to do something a few clicks should handle.
Thanks again for pointing me to opennms :)
