Using the AOM Dashboard to Display CCI Metrics

Constraints

Only one Prometheus instance for cloud services can be created in an enterprise project.

Step 1: Create a Prometheus Instance

1. Log in to the AOM console.
2. In the navigation pane, choose Prometheus Monitoring > Instances. On the displayed page, click Add Prometheus Instance.
3. Set the instance name, enterprise project, and instance type.
   

   If the CCE Cloud Bursting Engine for CCI add-on is being used or required, the CCE cluster also needs this Prometheus instance, with the instance type set to Prometheus for CCE.

   

4. Click OK.

Step 2: Connect Metrics Using the CCI Console

1. Log in to the CCI 2.0 console.
2. Select the target namespace, click Edit in the Operation column, and then enable AOM (Optional).
3. Select the AOM instance. For details about how to create an AOM instance, see Step 1: Create a Prometheus Instance.
4. Click OK.

Step 3: Create a Dashboard

1. Go to the AOM console. In the navigation pane, choose Dashboard. On the displayed page, click Add Dashboard.

2. Click the name of the created dashboard to go to the details page.
3. Click Add Chart, enter the title, select Prometheus statement, add a statement, and click Save. For details about CCI dashboard metrics, see Table 1.
   The following is an example statement for querying the CPU usage of all pods:

   sum(rate(container_cpu_usage_seconds_total{cluster="cci", image!=""}[5m])) by (pod, namespace) / (sum(container_spec_cpu_quota{cluster="cci", image!=""}/100000) by (pod, namespace)) * 100

   Dimension	Category	Metric Name	Definition
   Deployment	CPU metrics	CPU Usage	CPU usage
   		Used CPU	Used vCPUs
   	Memory metrics	Memory Usage	Memory usage
   		Used Memory	Used memory
   	Network metrics	Network Rate	Network rate
   		Packet Loss	Network packet loss rate
   Pod	CPU metrics	CPU Usage	CPU usage
   		Used CPU	Used vCPUs
   	Memory metrics	Memory Usage	Memory usage
   		Used Memory	Used memory
   	Network metrics	Network Rate	Network rate
   Container	CPU	CPU Usage	CPU usage
   	Memory metrics	Memory Usage	Memory usage

4. View the metrics on the AOM 2.0 dashboard.
