Custom histogram aggregation possible?

[MichaelLogutov]

Hello.
Is it possible to write custom histogram aggregation like, for example, victoria metrics histogram? Or the only way right now is to emulate this with a dynamic growing list of counter instruments?

[cijothomas]

As of today, there is no ability to write custom aggregators. There is no spec written for it yet, so naturally if there is a spec requirement, then only it'll be added.

Thanks.
I saw aggregation enum and thought that using enum is not flexible in terms of extendability for the future. So maybe you should look into that while you're at RC?

[cijothomas]

Could you point to the specific class/enum? Aggregation is not exposed anywhere to the user (internal only), so if there is a "leak", would like to know.

Ah, yeah - my bad. Missed that MetricStreamConfiguration.Aggregation is internal. Ok then.
