From a097b3e7a108852868155b6d979c165be91f4360 Mon Sep 17 00:00:00 2001 From: Pat Riehecky Date: Thu, 27 Apr 2023 10:14:24 -0500 Subject: [PATCH] feat: add metrics from cluster-example-monitoring.yaml This adds the metrics from cloudnative-pg/blob/docs/src/samples/cluster-example-monitoring.yaml Since these metrics are in the sample, it is nice to have them in the defaults.
