Threshold Alert Configuration

Configure alert thresholds for monitoring metrics (warning alert, critical alert, emergency alert). The system triggers alerts based on threshold configuration and collected metric data.

Operational Steps​

1. Setting Labels for Monitoring Services (Optional)​

If you need to categorize alerts, you can set labels for the monitored targets. For example: If you have multiple Linux systems to monitor, and each system has different monitoring metrics, such as: Server A has available memory greater than 1G, Server B has available memory greater than 2G, then you can set labels for Server A and Server B respectively, and then configure alerts based on these labels.

Creating Labels​

Navigate to Label Management -> Add Label

As shown in the image above, add a new label. Here we set the label as: linux:dev (Linux used in development environment).

Configuring Labels​

TODO Update image name threshold

As shown in the image above, click on Add Label.

Select our label, here demonstrated as selecting the linux:dev label.

Creating Threshold Rules​

Navigate to [Threshold Rules] -> [Add Threshold Rule] -> [Confirm Configuration]

The above image explains the configuration details:

  • Metric Object: Select the monitoring metric object for which we need to configure the threshold. For example: Under website monitoring type -> under the summary metric set -> responseTime metric.
  • Threshold Rule: Use this expression to calculate whether to trigger the threshold. Expression variables and operators are provided on the page for reference. For example: Set an alert to trigger if response time is greater than 50, the expression would be responseTime > 50. For detailed help on threshold expressions, see Threshold Expression Help.
  • Alert Level: The alert level triggered by the threshold, from low to high: warning, critical, emergency.
  • Trigger Count: Set how many times the threshold must be triggered before the alert is actually triggered.
  • Notification Template: The template for the notification message sent after the alert is triggered. Template variables are provided on the page. For example: ${app}.${metrics}.${metric} metric value is ${responseTime}, which is greater than 50 triggering the alert.
  • Bind Label: Select the label we need to apply. If no label is selected, it will apply to all services corresponding to the set metric object.
  • Apply Globally: Set whether this threshold applies globally to all such metrics, default is no. After adding a threshold, it needs to be associated with the monitoring object for the threshold to take effect.
  • Recovery Notification: Whether to send a recovery notification after the alert is triggered, default is not to send.
  • Enable Alert: Enable or disable this alert threshold configuration.

The threshold alert configuration is complete, and alerts that have been successfully triggered can be viewed in the [Alert Center]. If you need to send alert notifications via email, WeChat, DingTalk, or Feishu, you can configure it in [Alert Notifications].
