> Providing JMX metrics via jolokia to Prometheus does not work well with complex types.  We are providing several metric sets - engine stats, worker pool stats, requests, etc. as beans which needs to be flattened.  Simple parameters are ok to the metrics methods, but simple results are required.
> We need to make sure that at least statistics are available on:
> * number of plans waiting to be processed - this will be a primary metric for determining horizontal scale out
> * amount /%of buffer memory used - this will be a primary metric for determining if pods need to be allocated with more memory/disk
> Ideally alerting could be available on percent utilization - but we could also add a metric such as out of disk count to provide a hard count of exceptional conditions.
> It's assumed that cpu utilization will be monitored from the pod itself - which will be a primary metric for determining if pods should be allocated with more cpu resources.
