Portworx Alerts
PX provides a way to monitor your cluster using alerts. It has a predefined set of alerts which are listed below. The alerts are broadly classified into the following types based on the Resource on which it is raised
- Cluster
- Nodes
- Disks
- Volumes
Each alert has a severity from one of the following levels:
- INFO
- WARNING
- ALARM
List of Alerts
