Monitoring CCE Metrics

Procedure

1. Subscribing to AOM 2.0 for the First Time and Granting Permissions
2. Monitoring Containers: Purchase a cluster and node on CCE. The ICAgent is then automatically installed to report cluster metrics to AOM.
3. Setting an Alarm Action Rule: Create an alarm action rule and associate it with an SMN topic and a message template. If the CCE metric data meets the alarm condition, the system sends an alarm notification accordingly.
4. Setting an Alarm Rule: Create an alarm rule for the CCE metric. If the metric data meets the alarm condition, an alarm is generated.

Preparation

This section uses a CCE metric as an example. You need to purchase a cluster and node in CCE in advance. For details, see Buying a CCE Standard/Turbo Cluster and Creating a Node. If you already have a cluster and node, skip this step.

Subscribing to AOM 2.0 for the First Time and Granting Permissions

3. Click OK.

Setting an Alarm Rule

Metric alarm rules can be created using the following modes: Select from all metrics, and PromQL.

The following uses Select from all metrics as an example.

1. In the navigation pane, choose Alarm Management > Alarm Rules. Then, click Create.
2. Set basic information about the alarm rule by referring to Table 2.

   Table 2 Basic information

   Parameter	Description	Example
   Rule Name	Name of the rule. Enter a maximum of 256 characters and do not start or end with any special character. Only letters, digits, underscores (_), and hyphens (-) are allowed.	monitor_cce
   Enterprise Project	Select the required enterprise project. The default value is default.	default
   Description	Description of the rule. Enter up to 1,024 characters. In this example, leave this parameter blank.	-

3. Set the detailed information about the alarm rule.
   1. Rule Type: Metric alarm rule.
   2. Configuration Mode: Select from all metrics. Then you can set alarm conditions for different types of resources.
   3. Select a target Prometheus instance from the drop-down list. In this example, select Prometheus_AOM_Default.
   4. Set alarm rule details by referring to Table 3.

      After the setting is complete, the monitored metric data is displayed in a line graph above the alarm conditions. You can click Add Metric to add more metrics and set the statistical period and detection rules for them.
