Hello! - had a question for the group. Is there a good prometheus metric to use to catch when a clusterfilter compile error occurs? Doesn’t look like the daemon set pod restarts or stays in an unready state when this happens. We caught it because we started have coredns load issues. Would like to catch it before that happens next time 🙂
