Aggregate metrics for inflight activations.
* `openwhisk.histogram.loadbalancer<controllerId>_activationsInflight_count`
(histogram) - Records the number of activations being worked upon for a given
controller. As a histogram it would give a distribution of inflight activation
count within a flush interval.
-* `openwhisk.histogram.loadbalancer<controllerId>_memoryInflight_count`
(histogram) - Records the amount of RAM memory in use for in flight
activations. This is not actual runtime memory but the memory specified per
action limits.

activations. This is not actual runtime memory but the memory specified per
action limits. **invokerType** defines whether it is a managed or a blackbox
invoker.

-* `openwhisk.counter.loadbalancer_invokerOffline_count` - Records the count of
invokers considered offline based on health pings.

Records the count of managed invokers considered healthy based on health pings.
**invokerType** defines whether it is a managed or a blackbox invoker.

`openwhisk.histogram.loadbalancer_totalUnresponsiveInvoker<invokerType>_count`
- Records the count of managed invokers considered unresponsive when health
pings arriving fine but the invokers do not respond with active-acks in given
time. **invokerType** defines whether it is a managed or a blackbox invoker.
+* `openwhisk.histogram.loadbalancer_totalOfflineInvoker<invokerType>_count` -
Records the count of managed invokers considered offline when no health pings
arrive from the invokers. **invokerType** defines whether it is a managed or a
blackbox invoker.
+* `openwhisk.histogram.loadbalancer_totalUnhealthyInvoker<invokerType>_count`
- Records the count of managed invokers considered unhealthy when health pings
arrive fine but the invokers report system errors. **invokerType** defines
whether it is a managed or a blackbox invoker.
