Click the Alerts
icon on the left pane.Select Kubernetes monitoring from the Search capability drop-down list.
Select a service from the Search service drop-down list.
Click Add alert to add a new alert. The following Add alert window appears.
In the Add alert window fill in the following details:
| Field | Description |
|---|---|
| Alert name | Name of the alert. Note that only alphanumeric and a single space between words are allowed. |
| Service | List of available services. |
| Metric | The metric for which you want to trigger an alert. The threshold is matched with the metric's real-time value. For more information about the supported metrics for each capability, see Supported metrics for alerts. Note: The following fields are displayed based on the metrics you have selected. |
| Aggregation type | The options available for this drop-down are based on the metric you select in the Metric drop-down list. For the available options, see Aggregation type options. |
| Operator | Select greater or lesser than, equal to, greater than or equal to, or lesser than or equal to. |
| Threshold value | Select a threshold value. Alerts are triggered if the value over the given period is greater than or equal to the threshold you select. |
| Number of breaches | An alert is triggered if the threshod breaches the set value. |
| Time period | The length of time for which the alert is evaluated. Note: When there is a latency between the agent and backend communications, alerts configured for one minute may have some accuracy issues. |
| Recovery period | An open alert is marked as closed if there are no new breaches after it reaches the specified period |
| Silence period | The time during which alerts are not triggered. |
| Notification channels | The list of configured notification channels. You can select multiple notification channels that are available. If you haven't added a notification channel yet, click Create new channel. For more informaiton about adding notification channels, see step 4 for adding an email notification channel, or see step 4 for adding a slack channel, or see step 4 for adding a webhook notification channel. |
| Alert tags | Enter a key and value for an alert tag. The best practice for naming a key would be the capability name followed by the application name at the backend. For example, KM-K8-1 where KM is the capability name and K8-1 is the service name. The value would be the name of the metrics followed by the capability. For example Node-storage-KM, where Node-storage is the metrics and KM is the capability name. |
The alert is added successfully.
