Depending on the version of client_golang and metrics format (Prometheus vs OpenMetrics), bucket names may contain either integer or float formatting. Use a regexp match to select either format. Signed-off-by: SuperQ <[email protected]>

That doesn't seem correct. We need to escape the . in order to have a literal . match instead of a regexp any character match.

Of course, you're right @SuperQ. What you need instead then is to double-double-escape! i.e.
- kubeApiserverReadResourceLatency: '1(\.0)?',
- kubeApiserverReadNamespaceLatency: '5(\.0)?',
- kubeApiserverReadClusterLatency: '30(\.0)?',
- kubeApiserverWriteLatency: '1(\.0)?',
+ kubeApiserverReadResourceLatency: '1(\\\\.0)?',
+ kubeApiserverReadNamespaceLatency: '5(\\\\.0)?',
+ kubeApiserverReadClusterLatency: '30(\\\\.0)?',
+ kubeApiserverWriteLatency: '1(\\\\.0)?',which would produce queries like:
sum by (cluster) (cluster_verb_scope_le:apiserver_request_sli_duration_seconds_bucket:increase30d{verb=~"POST|PUT|PATCH|DELETE",le=~"1(\\.0)?"})
