Google Cloud Kubernetes Engine

Google Cloud Kubernetes Engine - Overview

Google Cloud Kubernetes Engine is an enterprise-grade platform for containerized applications, including stateful and stateless, AI and ML, Linux and Windows, complex and simple web apps, API, and backend services. It aids you in providing automatic application deployment, scaling and management of Nodes, Pods and Containers.

Monitored Parameters

Go to the Monitors Category View by clicking the Monitors tab. Click on the Kubernetes Engine instance available under Google Cloud in the Cloud Apps section. Displayed is the Google Cloud Kubernetes Engine bulk configuration view distributed into three tabs:

Availability tab gives the availability history for the past 24 hours or 30 days.
Performance tab gives the health status and events for the past 24 hours or 30 days.
List view tab enables you to perform bulk admin configurations.

By clicking a monitor from the list, you'll be taken to the Google Cloud Kubernetes Engine dashboard. It has 4 tabs:
