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].
