Sorry for the inconvenience, this has already been merged to be fixed in a 3.11.z release: https://github.com/openshift/cluster-monitoring-operator/pull/127 Hi Frederic, Thank you for letting me know. Do we have an ETA for the next ERRATA where the fix is implemented? I'm not aware of the schedule for z-stream releases, that question would need to go to the respective team taking care of that.
