Repeater config?? #586

Open telderfts opened 1 year ago

telderfts commented 1 year ago

I know that with StatsD you are able to configure a repeater backend so that metrics can be used by 2 different backends. Is it possible to do that with GoStatsD?

Hi

Sort of - gostatsd can have multiple backends configured, but only 1 of each type. Specifically the backends configuration item is actually a list, not a single value.

Right but does it support the repeater backend that StatsD does? And if so is there any documentation on how to configure it?

I don't know what the repeater backend in statsd is. If it just sends out the same statsd data it got in, then sort of yes, sort of no. There IS a statsdaemon backend, but it outputs over tcp, not udp. Unfortunately it's not documented (the documentation on older stuff tends to be lacking, unfortunately).

The code that reads the configuration is at https://github.com/atlassian/gostatsd/blob/master/pkg/backends/statsdaemon/statsdaemon.go#L261 though

Also note that it doesn't just proxy forward the data it receives - it still does aggregation, and sends the data out as statsd formatted data, on the normal flush interval.

Ok, we are trying to migrate away from Graphite to Prometheus but have to make a gradual move so we were wanting to use the StatsD Exporter to do this but the best way for us is to have the repeater backend set on gostatsd so that graphite can still get data from gostatsd as well as it being sent to the exporter. I know that StatsD has that backend so I just need a definitive answer as to whether or not GostatsD has it and if it did how we would configure it.

You might instead try running gostatsd under 2 configurations (separate servers) and use a UDP repeater to send to both. Statsd clients send to the repeater, which sends to the 2 separate gostatsd instances. That will help you through the transition.
