Following on the Cloudstack Collaboration Conference last month in Amsterdam, we are releasing the tooling we use in our public cloud to cope with large Cloudstack implementations.
Today, we publish our collectd Cloudstack plugin which can gather all these metrics:
- Number of instances : Total, Running and Stopped
- Public IPs: Total and Used
- Private IPs: Total and Used
- Memory: Total (with and without over-provisioning), Allocated and Used
- CPU: Total (with and without over-provisioning), Allocated and Used
- Primary Storage: Total (with and without over-provisioning), Allocated and Used
- Secondary Storage: Total and Used
- LocalStorage : Total and Used
- Network: Read and Write
- Console Proxy : Number of active sessions
Once collected by a collectd probe machine or directly on your CloudStack Server you can push these metrics in a graphing server like we do. We use Graphite to generate a nice dashboard overview of this infra.
Installation is quite simple, just drop the plugin in the plugins folder of your collectd installation and add the following configuration to your collectd.conf:
<LoadPlugin python> Globals true </LoadPlugin> <Plugin python> # cloudstack.py is at /usr/lib/collectd/cloudstack.py ModulePath "/usr/lib64/collectd/" Import "cloudstack" <Module cloudstack> Api "https://mycloudstack.com:443/client/api" Auth "True" ApiKey "RANDOM-KEY-FROM-CS" Secret "SECRET-FROM-CS" </Module> </Plugin>
