+plugin.@PLUGIN@.excludeMetrics
+:   String used to exclude metrics from the report. It can be specified multiple times.
+    Parsed as regular expression. Note, ^ and $ are automatically added around the string.
+    By default no metric is excluded.
+    For example, to exclude all cache metrics, use: `excludeMetrics = cache.*`
