Citrix Application Delivery Management

Configure thresholds in service graph

As an administrator, you can configure thresholds for Kubernetes services. Citrix 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.

    Configure 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 same as Threshold 2 value.

  4. Click Save.

    Configure threshold

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

Single threshold

Consider a scenario that you have selected single threshold for both high service response time and high errors, and thresholds exceeded according to the following example:

Configured threshold values Exceeded threshold values
High service response time = 250 ms High service response time = 330 ms
High errors = 10 High errors = 15

In this scenario, Citrix ADM:

  • Compares the current response time (330 ms) and high errors (15) with the configured threshold values for service response time (250 ms) and error counts (10)

  • Calculates the total penalty

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

Double threshold

Consider a scenario that you have selected double threshold for both high service response time and high errors, with the following configurations:

Configured threshold values Exceeded threshold values
High service response time (threshold 1) = 250 ms and High service response time (threshold 2) = 350 ms) High service response time = 330 ms
High errors (threshold 1) = 10 and high errors (threshold 2) = 20 High errors = 15

In this scenario, Citrix ADM:

  • Compares the current response time (300 ms) and high errors (15) with the configured threshold values.

  • Calculates the total penalty

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