Monitoring System

The Virtual Cluster provides a monitoring system which gives an overview of the uptime and different CPU and network metrics for all instances. Running instances are automatically reporting their performance data to a database of the monitoring system and the data is displayed by a web frontend. This web frontend can be accessed by entering:

https://<name_or_ip_of_the_virtual_cluster>/monitoring

in the address bar of a web browser using the user credentials as defined when creating the user account on the Virtual Cluster.

Access Privileges#

A different access level for the monitoring system is granted based on the authorization level for the created account. Unlike admin users, regular users are unable to edit or create new dashboards.

Note

Refer to Authentication and Authorization for additional details regarding user authorization.

Alerting#

The monitoring system comes with pre-defined alerts, i.e., it can send notifications in case of issues which require human attention, e.g., if running out of disk space. Notification for the alerts is enabled by default and is being controlled by the configured notification channel. In order to adjust the configuration or create a new notification channel, navigate to ‘Alerting’ > ‘Notification Channels’ to view the existing notification channels.

Replacing a Notification Channel#

If the same channel type should be kept you can edit the existing notification channel(s). Alternatively remove the ‘Default’ flag under ‘Notification settings’ and create a new notification channel with this flag set to create a new notification channel.

Adding a New Notification Channel#

Note

If there is already a notification channel please refer to Replacing a Notification Channel

On the notification channel page click ‘New channel’ and configure it accordingly. The required information varies on the type. Please refer to the official Grafana documentation for additional help.

Warning

Make sure to enable the ‘Default’ flag under ‘Notification settings’ in order to apply it to existing alerts.
