I’ve just upgraded my OpenBSD’s Xymon server from 4.3.9 to 4.3.10. It was so simple that it deserved a simple note to:
confirm you don’t need the “--rrdlib” parameter to configure xymon-server with RRDtool support on OpenBSD (5.1) anymore; applause for “gmake install” to be keeping the initial (modified) configuration files untouched. Congratz Henrik!Continue reading...
Lately, I couldn’t publish any more articles on my WordPress instance. Instead of the “Publish” button, I only got “Submit For Review”. As I upgraded WordPress recently, I thought this might be either a new feature or some permissions that were dropped ; but I just couldn’t find any.
After a few dig&read on the Internet, most of this behavior seemed to reveal a problem with the database. And I recently had a few bunch of crashes on the infrastructure ; thanks to my electric power provider…Continue reading...
I’ve been using various monitoring software for a long time now. I always use two kinds of monitoring tools: service checkers, like Nagios, Monit… and metrics graphers, like RRDtool, Cacti, Munin, … I like the Xymon software, AKA Hobbit Monitor, because it can achieve both, uses very low resources and can be customized quite easily.
I used to run it on a FreeBSD virtual machine with ZFS activated. The idea was to compress and deduplicate the RRD data. But in fact, the RRD files weight less than 100MB and ZFS is of no use here. Plus, it seems my 3 virtual disks configuration makes the system lagging a lot ; or is it just the FreeBSD implementation. Anyway, that machine keeps sending timeouts and I can get why. Plus, comparing performance of both VMs, FreeBSD and VMware tools doesn’t seem to use less of my ESXi resources. So it’s time to replace it by some OS that never fails me: OpenBSD.Continue reading...
This is just a quick note so that I can remember later on how to update my standalone ESXi v5 from the CLI.Continue reading...
Last time, I had a look at how to monitor VMware vSphere from FreeBSD using the Perl SDK . Quite simple using the ports!
Believe it or not, installing and running the VMware vSphere Perl SDK on OpenBSD is as simple as breathing. Here’s the POC.Continue reading...
