Currently the /metrics endpoint does not compress the response.

This causes about 1MB to be transferred on each scrape, per instance. With 20 instances this eats up a LOT of bandwidth and causes slow scrapes.

How do we enable gzip for metrics?

At the moment, this is not possible to enable Gzip compression on this endpoint but that sounds a reasonable RFE.

We could add a "gzip-enabled" attribute to the metrics / microprofile-metrics-smallrye subsystem. When it is enabled, we would wrap the metrics HTTP handler in a EncodingHandler for gzip (that should be similar to the code in org.wildfly.extension.undertow.filters.GzipFilter).

@Jason, what do you think?

That does sound like a reasonable request. I'll try to file an RFE for that today. I can't promise on WHEN it will ship, but I'll get it on the list.

Hi. I'm sorry I missed the responses.

If you can do any of that it sounds amazing!

Do you have any ref to a ticket at issues.redhat.com?
