When applications run on Kubernetes clusters, tracking pod-level resource consumption helps identify performance bottlenecks and capacity issues. Enterprise Distributed Application Service (EDAS) integrates with Prometheus and provides a built-in Grafana dashboard that displays CPU, memory, and network metrics for each pod in your application. You can also modify dashboard properties such as the time interval and refresh rate.
Prerequisites
Before you begin, make sure that you have:
An application deployed on a Kubernetes cluster in EDAS
Open the Prometheus dashboard
Log on to the EDAS console.
In the left-side navigation pane, choose Application Management > Applications.
In the top navigation bar, select a region and select a microservices namespace from the Microservices Namespace drop-down list.
Select Kubernetes Cluster from the Cluster Type drop-down list, and then click the name of the target application.
In the left-side navigation pane, choose Monitor > Prometheus. The Kubernetes Container Replica page opens in Grafana.
Dashboard metrics
The dashboard organizes metrics into five categories. Use the pod selector at the top of the page to switch between pods and view metrics for different pods.
Pod information
| Metric | Description |
|---|---|
| Pod IP Address | The IP address assigned to the pod |
| Pod Status | The current status of the pod |
| Pod Container | The containers running inside the pod |
| Container restarts | The number of container restarts |
Overall resource usage
| Metric | Description |
|---|---|
| Pod CPU usage | Total CPU consumed by the selected pod across all its containers |
| Pod memory usage | Total memory consumed by the selected pod across all its containers |
CPU metrics
| Metric | Description |
|---|---|
| Pods CPU usage | Aggregated CPU consumption across all pods in the application |
| All processes CPU usage | Total CPU consumption of all processes |
Memory metrics
| Metric | Description |
|---|---|
| Pods memory usage | Aggregated memory consumption across all pods in the application |
| All processes memory usage | Total memory consumption of all processes |
Network metrics
| Metric | Description |
|---|---|
| Network I/O pressure | Overall network load indicator for the pod |
| Pods network I/O | Inbound and outbound network traffic for all pods in the application |
| All processes network I/O | Total network traffic for all processes |
