const UprobeString = "uprobe"

Define a constant strings for Uprobe, Fentry and Fexit. Uprobe has the same kernel ProgramType as Kprobe, and Fentry and Fexit both have the Tracing ProgramType, so we can't use the ProgramType String() method above.

Functions

func BpfNodePredicate added in v0.6.0 

func BpfNodePredicate(nodeName string) predicate.Funcs

Only reconcile if a program has been created for a controller's node.

func DiscoveredBpfProgramPredicate 

func DiscoveredBpfProgramPredicate() predicate.Funcs

Only reconcile if a bpfprogram has been created for a controller's node.

func HasMonitoringAPI added in v0.6.0 

func HasMonitoringAPI(client discovery.DiscoveryInterface, setupLog logr.Logger) (bool, error)

HasMonitoringAPI returns true if the monitoring.coreos.com API group is available on the cluster, indicating the Prometheus Operator (or compatible) is installed.

func IsOpenShift added in v0.6.0 

func IsOpenShift(client discovery.DiscoveryInterface, setupLog logr.Logger) (bool, error)

Returns true if the current platform is Openshift.
