ScaleCamp - State of the Nation for Monitoring

Where are we now and what's broken with it?

• Cacti


• Collectd


• Munin


• Ganglia


• Hyperic


• Zabbix


• Zenoss

People are almost getting to the point of needing more powerful machines to do the monitoring than the app servers! Maybe something's broken somewhere...

RRDTool - overall, the consensus seemed to be that this was a little dated.

1. Does lots of writes due to the way it stores data


2. throws away data by the way it aggregates - to see fine-grained data of last years sales, you need to keep a backup of the files / graphs, rather than being able to query it.


3. can't be cleansed of bad data, or it's a bitch of a job to do so.

Alternative options

• hbase


• reconnoiter


• Tokyo Tyrant / Cabinet


• timesplicedb looks to be an interesting attempt to provide a replacement. More language bindings needed, don't be shy!

A good start to the conference for me and it gave me a flavour of the depth and breadth of discussions available.
