Adding trendline to your graphs

vuksan — Thu, 08 Mar 2012 17:44:16 +0000

As part of our upcoming release of Ganglia 3.3.2 you will have the ability to add a trend line to any host metric. Let’s say you wanted to know when you will need to add more disk space to a particular machine.

We are “safe” for about a year. Or let’s say you wanted to see how your web server 90th percentile has trended.

This takes calculates trend based on last six month of data (which is a default). That looks pretty good however let’s see how it looks if we take 12 months of data

Not so good. Trending interface has easy controls that allow you to easily change how far to extend the trend line and how far back to go
e.g.

Enjoy.

Putting metrics data on a common “bus”

vuksan — Fri, 30 Dec 2011 03:14:49 +0000

Patrick Debois has kicked of an interesting set of projects to put metric information on a common “bus”. For example he has implemented a ruby based daemon that parses Ganglia gmond packets and puts them on a ZeroMQ pub/sub bus. Once it’s there you can “subscribe” with a client of your choice and do transforms to the data e.g.

feed graphite or another monitoring tool
insert data into a SQL database
feed Nagios using passive checks

Thanks to Patrick for a great idea and implementation. Now let’s get to work on useful subscribers.
