CheckForUnmountableSecrets checks to be sure that all the referenced secrets are mountable (by service account).

CheckMissingMountedSecrets checks to be sure that all the referenced secrets are present (not synthetic).

FindHPASpecsMissingCPUTargets scans the graph in search of HorizontalPodAutoscalers that are missing a CPU utilization target.

FindHPASpecsMissingScaleRefs finds all Horizontal Pod Autoscalers whose scale reference points to an object that doesn't exist or that the client does not have the permission to see.

FindMissingLivenessProbes inspects all PodSpecs for missing liveness probes and generates a list of non-duplicate markers.

FindMissingSecrets inspects all PodSpecs for any Secret reference that is a synthetic node (not a pre-existing node in the graph).

FindOverlappingHPAs scans the graph in search of HorizontalPodAutoscalers that are attempting to scale the same set of pods.

FindRestartingPods inspects all Pods to see if they've restarted more than the threshold.

FindUnmountableSecrets inspects all PodSpecs for any Secret reference that isn't listed as mountable by the referenced ServiceAccount.

HPAMissingCPUTargetError denotes an error where a Horizontal Pod Autoscaler does not have a CPU target to scale by.

HPAMissingScaleRefError denotes an error where a Horizontal Pod Autoscaler does not have a reference to an object to scale.

HPAOverlappingScaleRefWarning denotes a warning where a Horizontal Pod Autoscaler scales an object that is scaled by some other object as well.
