Monitoring Application Latency on Anthos Clusters

A.

The correct answer is A. Install Anthos Service Mesh on your cluster. Use the Google Cloud Console to define a Service Level Objective (SLO), and create an alerting policy based on this SLO.

Explanation: Anthos Service Mesh is a powerful tool for monitoring and managing traffic within a cluster. It provides detailed metrics and insights into traffic behavior, as well as the ability to set up and manage Service Level Objectives (SLOs) for the applications running on the cluster. SLOs are a key aspect of Site Reliability Engineering (SRE) practices, as they provide a way to define and measure the reliability and performance of an application.

To set up an alert based on request latency, you would first install Anthos Service Mesh on your cluster. This can be done using the Anthos Console, which provides a user-friendly interface for managing and monitoring clusters. Once installed, you would define an SLO that specifies the maximum latency that is acceptable for your application. For example, you might set an SLO that requires 99% of requests to be completed within 100ms.

Once you have defined the SLO, you can create an alerting policy based on this SLO. This can be done using the Anthos Console, which allows you to specify the conditions under which an alert should be triggered. For example, you might set up an alert that triggers if the latency of requests exceeds the SLO for more than 5 minutes.

By using Anthos Service Mesh to monitor and manage your application, you can ensure that it is reliable and performant. With the ability to define SLOs and set up alerts based on these SLOs, you can quickly identify and resolve issues before they become major problems.
