Description Juan Vallejo 2018-10-22 20:48:45 UTC
Description of problem:

The service-serving-cert-signer is making over 30,000 requests within the span of 2 hours (since bringing up a cluster using the installer).

For comparison, the apiserver performs 24,000 requests within the same time period.

Hi Juan, try running your metrics with docker.io/mrogers950/origin-service-serving-cert-signer:limittest ? This is an image built with https://github.com/openshift/service-serving-cert-signer/pull/37. We should see a reduction in the amount of API requests over time.

Comment 2 Neelesh Agrawal 2019-01-25 21:19:42 UTC
I think we had couple of rounds of reduction on request-load. Is this still an active issue? Can this be closed now?

Comment 3 Matt Rogers 2019-01-25 21:34:33 UTC
Yes, the operator no longer continually sync loops, which was the root cause of our constant API hammering.
