Re: Metrics for custom modules

[Zhitao Li]

Hi Joseph,

That sounds great! Let me test this out.

Any gotcha that I should be careful of? (internal locking, performance,
conflict, etc etc).

Thanks.

As long as you're using libprocess to write your modules, you can add your
metrics via `process::metrics::add(...)`.  Those will be exposed via the
same old `/metrics/snapshot` endpoint.

Metrics for custom modules

[Zhitao Li]

Hi,

I'm not sure whether this has been mentioned, but is it possible to reuse
Mesos's metric system for custom modules?

For context, we are planning to turn on some agent-side modules at many
machines, but we face the question of how we'll monitor their behavior: we
can reinvent some wheels to export metrics by ourselves (or probably even
use libprocess code), but I wonder whether Mesos should provide an easier
solution to allow metrics be reported to the same metrics system of
master/agent (either merged with standard metrics, or reported separately).

Any thought about this?
