collect metrics in logs

[xuwenyihust]

Is it possible to collect the metrics into some csv or json format logs?
Would be great to record these metrics by some intervals to get a better sense of cluster health.
Trying to build it myself.

@xuwenyihust I think it is doable. We currently don't a use-case for this. You can probably implement your own Service to do it similar to DefaultMetricsReporterService or GraphiteMetricsReporterService.

@lindong28 I'm temporally redirecting the collected metrics from STDOUT to a log file, and then parse them using scripts.
Looking for some cleaner ways to do this.

Ideally it can be somehow separated from the existing logging so that the reporting intervals and other configs can be modified without affecting the existing real-time reporter.

Thank you

@xuwenyihust Sorry, we don't have plan to implement this because we don't have use-case for this at LinkedIn and there doesn't seem to be many users that are interested in this in open source. You are welcome to implement your own Service that does it in a clean way. I think it is doable by design.
