Marcus Sorensen commented on CLOUDSTACK-7583:
---------------------------------------------
Ok, thanks. I'll give it a try. I eventually gleaned that the uri was a
"graphite://" by reading the code (and actually just stumbled across this
feature by implementing a new scheduled task and using StatsCollector as a
template, I've been toying with a DRS type service that would watch host stats
from StatsCollector and potentially initiate migrations for resource
balancing).
Normally for documentation on new features I find a functional spec at
https://cwiki.apache.org/confluence/display/CLOUDSTACK/Design, and between that
and the jira ticket there's enough information on the implementation to
understand how to use it (and as a developer, how it works). I suppose at some
point that needs to be converted and put into the docs, but anyone can do that
if they have a functional spec to work off of.

> It would be very useful if the StatsCollector inside the management server
> could also send all the stats collected to a Graphite server in addition to
> the usage database.
> This allows for easy graph generation for CPU, Network and Disk I/O of
> Instances and hosts.
> Via a global setting we can configure:
> * Graphite host
> * Graphite port
> * Key prefix
> We can then send Instance and Host information, like:
> cloudstack.stats.instances.<vm id>.cpu.num 1
> cloudstack.stats.instances.<vm id>.cpu.utilization 50
> cloudstack.stats.instances.<vm id>.network.read_kbs 4817
> cloudstack.stats.instances.<vm id>.network.write_kbs 672
