Functions

func HandleSubclusterDelete 

func HandleSubclusterDelete(vdb *vapi.VerticaDB, scOid string, log logr.Logger)

HandleSubclusterDelete will cleanup metrics upon subcluster deletion. It will clear out any metrics that are subcluster specific.

func HandleVDBDelete 

func HandleVDBDelete(namespaceName, vdbName string, log logr.Logger)

HandleVDBDelete will cleanup metrics when we find out that the VerticaDB no longer exists. This should include all metrics that include the VerticaDB name in its metrics.

func HandleVDBInit 

func HandleVDBInit(vdb *vapi.VerticaDB)

HandleVDBInit will initialized metrics that use verticadb as a label. This is necessary to fill in a missing series with a known verticaDB. Otherwise, a metric won't be displayed until we have set some value to it. This may break dashboards that assume the metric exists.

func MakeSubclusterLabels 

func MakeSubclusterLabels(vdb *vapi.VerticaDB, scOid string) prometheus.Labels

MakeSubclusterLabels returns a prometheus.Labels that includes the VerticaDB and subcluster name.

func MakeVDBLabels 

func MakeVDBLabels(vdb *vapi.VerticaDB) prometheus.Labels

MakeVDBLabels return a prometheus.Labels that includes the VerticaDB name
