PerformanceMonitoringTools

If you want to do some performance monitoring, here are some tools.

Canary is an OpenStack service that accesses statistics stored in RRD format (generally collected by `collectd`), released by Gridcentric under the Apache 2.0 license. Canary adds the ability to see real-time graphs of host statistics in the Horizon dashboard as well as the ability to query stats via the nova API / novaclient.

A blog post from Piotr Siwczak of Mirantis entitled Some practical considerations for monitoring in OpenStack cloud also mentions the following tools:
 * Nagios
 * Ganglia (supports sFlow)
 * Cacti
 * Zabbix
 * Zenoss ZenPack for OpenStack
 * sFlowTrend
