Monitoring, another way
Some friends told me for a while about collectd, why I should look at it, why munin is so painful and so on. If you’ve been reading my posts you know I have tweaked a little my $WORK munin install to make it faster and lighter. But I finally took time to explore collectd, and I regret to not have done this before. It has so many pros that I decided to implement it in parallel with munin (because I can’t afford being blind on metrics). But collectd comes without an UI : it “only” collectds data, but that’s not a problem. There are various web interfaces and after giving a look to a bunch of them I fell in love with Lindsay Holmwood‘s Visage.
This piece of software is definitely cool : all graphs are rendered live in your browser in SVG. Yes ! Realtime graphs, no need for crappy flash s***, zoom. It is based on sinatra, haml and some JS libraries (I won’t talk about this, my JS foo is deeper than the Mariana Trench). But it lacked some features : it’s OK when you have a few hosts but when the hosts list starts being loooong then the interface needs some improvements. So I forked it on github and implemented (some parts of) what I needed. My github fork has host grouping & per host profiles. Check this out and enjoy Visage !
Now working on sets of graphs 🙂
