azure-scheduledevents-exporter

Azure ScheduledEvents Exporter

Prometheus exporter for Azure ScheduledEvents (planned VM maintenance) from the Azure API.

It fetches informations from http://169.254.169.254/metadata/scheduledevents?api-version=2017-08-01 and exports the parsed information as metric to Prometheus.

Hint: Interrested in automatic node draining for Kubernetes for Azure ScheduledEvents? see azure-scheduledevents-manager
