Cluster State Alerts


GridGain Web Console allows you to monitor the state of your cluster by configuring alerts for events occurring on the cluster. Whenever there is a change in the state of the cluster, such as a node join, an alert will be fired if one is configured. You can enable or disable alerts at any time, edit their default values, and choose to receive email/SMS notifications. By default, you will receive Web Console notifications in the Events tab.

You can mark all events as read, or delete them by clicking on the Actions tab, as shown in the picture above. Alerts can also be exported to a CSV file by clicking on the book icon.

If you are on a different screen on the Web Console when an event, for which an alert is configured, occurs on your cluster, the bell icon will fire a notification.
