Configure thresholds in service graph

As an administrator, you can configure thresholds for Kubernetes services. NetScaler® ADM displays the service status (Critical, Review, and Good) based on the service response time and error count. By default, you can view the Default Threshold (service response time = 200 ms and error count = 0) applied to all services.

Note

You cannot delete the Default Threshold.

To configure a new threshold:

In service graph:

1. Click the settings icon and select the Thresholds tab.

2. Click New Threshold to configure a new threshold.

   

   The New Threshold page is displayed.

3. Configure the following parameters:

   1. Name – Specify a name for the threshold.

   2. Under Microservices, select the services that you want to apply the threshold

   3. Under Thresholds, select Single or Double for High Response Time and High Errors

   4. Specify the threshold values.

      Note

      If you select double threshold, ensure:

      • Threshold 1 value is lesser than Threshold 2 value. For example, if you configure Threshold 1 as 250 ms, Threshold 2 must be 251 ms or higher.

      • Threshold 1 value must not be the same as Threshold 2 value.

4. Click Save.

   

   The threshold is successfully created. You can view the threshold details in the Thresholds page.

Single threshold

When you configure single threshold, NetScaler ADM:

• Compares the current values with the configured threshold values

• Calculates the total penalty based on the exceeded thresholds

• Displays the service score and service status based on the penalty calculation

Double threshold

When you configure double threshold, NetScaler ADM:

• Compares the current values with the configured threshold values

• Checks if the current values are:

  • Lesser than threshold 1

  • Between threshold 1 and threshold 2

  • Greater than threshold 2

• Calculates the total penalty based on the exceeded thresholds

• Displays the service score and service status based on the penalty calculation
