I think Joel did some work for the C* part.</p><p dir="auto" class="">What I think we need is <br class="">
- number of data points stored on a per tenant basis.<br class="">
Resolution could be something like "last minute" or<br class="">
"last 5 minutes" I.e. not realtime updates in the table.<br class="">
- Total number of data points (i.e. sum over all tenants)</p>

<li class=""><p dir="auto" class="">Query stats. This is probably more complicated, as <br class="">
querying on metrics that are still in some buffer is<br class="">
cheaper than over 3 years of raw data.<br class="">
To get started I'd go with # of queries per tenant and global<br class="">
Those could perhaps be differentiated on </p>

<li class="">raw endpoint</li>
<li class="">stats endpoint</li>

<li class=""><p dir="auto" class="">What about alerting? More alert definitions certainly<br class="">
need more cpu, so number of alert definitions per tenant<br class="">
and total would be another pair.</p>
<ul class="">
<li class="">does number of fired alerts also make sense?</li>
</ul></li>
</ul><p dir="auto" class="">The idea behind those is to get some usage figures of the<br class="">
shared resource "Hawkular metrics" and then to be able to <br class="">
charge them back onto individual tenants e.g. inside of <br class="">
OpenShift.</p>
