>                 Key: MESOS-4664
>                 URL: https://issues.apache.org/jira/browse/MESOS-4664
>             Project: Mesos
>          Issue Type: Improvement
>          Components: allocation
>            Reporter: Benjamin Mahler
>            Priority: Critical
>
> There are currently no metrics that provide visibility into the allocator, except for the event queue size. This makes monitoring an debugging allocation behavior in a multi-framework setup difficult.
> Some thoughts for initial metrics to add:
> * How many allocation runs have completed? (counter)
> * Current allocation breakdown: allocated / available / total (gauges)
> * Current maximum shares (gauges)
> * How many active filters are there for the role / framework? (gauges)
> * How many frameworks are suppressing offers? (gauges)
> * How long does an allocation run take? (timers)
> * Maintenance related metrics:
> ** How many maintenance events are active? (gauges)
> ** How many maintenance events are scheduled but not active (gauges)
> * Quota related metrics:
> ** How much quota is set for each role? (gauges)
> ** How much quota is satisfied? How much unsatisfied? (gauges)
>  
> Some of these are already exposed from the master's metrics, but we should not assume this within the allocator.
