2. In the navigation pane on the left, choose Access > Access Center.

   If the old Access Center is displayed, click Experience the new version in the upper right corner.

3. Select the check box next to APIs/protocols... under Types to filter out target cards.
4. Click Ingest Metric (AOM) or Ingest Trace (APM) to quickly ingest metrics or traces, or click Ingest Log (LTS) Details to ingest logs or check documents related to log ingestion.
   • Ingest Metric (AOM): AOM supports metric ingestion using open-source APIs and protocols. By clicking Ingest Metric (AOM), you can quickly ingest metrics using open-source APIs and protocols.
   • Ingest Trace (APM): AOM provides an entry for ingesting traces to APM using open-source APIs and protocols. By clicking Ingest Trace (AOM), you can quickly ingest traces using open-source APIs and protocols.
   • Ingest Log (LTS) Details: AOM provides an entry for ingesting logs to LTS using open-source APIs and protocols.
     • By clicking Details on Ingest Log (LTS) Details, you can check documents related to log ingestion. You can ingest logs according to the documents.
     • For some components, you can quickly ingest their logs by clicking Ingest Log (LTS). For example, the Cross-Account Ingestion - Log Stream Mapping card.

Ingesting Custom Prometheus Metrics to AOM

You can ingest custom Prometheus metrics. They can be automatically reported to AOM.

• Prerequisites
  • A Prometheus instance for ECS has been connected for monitoring. For details, see Creating a Prometheus Instance for ECS.
  • A host group has been created. For details, see (New) Managing Host Groups.
• Procedure

1. Log in to the AOM 2.0 console.
2. In the navigation pane, choose Access > Access Center. Click Experience the new version in the upper right corner of the page.
3. Click Custom Prometheus Metrics under APIs/Protocols..., and then click Ingest Metric (AOM) on the card to enter the configuration page.
4. Configure parameters for ingesting custom Prometheus metrics.
   1. Select a Prometheus instance.
      1. Instance Type: Prometheus for ECS is selected by default and cannot be changed.
      2. Instance Name: Select a Prometheus instance from the drop-down list.

         If no Prometheus instance is available, click Create Instance to create one.

   2. Select a host group.
      In the host group list, select a target host group.

      • If no host group is available, click Create Host Group to create one.
      • You can also perform editing, deletion, and other operations on the host group as needed. For details, see Other Operations.

      Collection configurations are delivered by host group. Therefore, it is easy for you to configure data collection for multiple hosts. When there is a new host, simply add it to a host group and the host will automatically inherit the log ingestion configurations associated with the host group.

   3. Configure the collection.
      Under Configure Collection, set parameters by referring to the following table.

      Table 2 Parameters for configuring a collection task

      Operation	Parameter	Description
      Basic Settings	Configuration Name	Name of a custom metric ingestion rule. Enter 1 to 50 characters starting with a letter. Only letters, digits, underscores (_), and hyphens (-) are allowed.
      Metric Collection Rule	Collection Target	Enter the target IP address and port number for collecting Prometheus metrics, for example, 10.0.0.1:3306.
      	Metric Collection Interval (s)	Interval for collecting metrics, in seconds. Options: 10, 30, and 60 (default).
      	Metric Collection Timeout (s)	Timeout period for executing a metric collection task, in seconds. Options: 10, 30, and 60 (default). The timeout period cannot exceed the collection interval.
      	Executor	User who executes the metric ingestion rule, that is, the user of the selected host group. By default, the executor is root.
      Other	Custom Dimensions	Dimensions (key-value pairs) added to specify additional metric attributes. You can click Add Dimension to add multiple custom dimensions (key-value pairs). Key: key of the additional attribute of a metric. Enter 1 to 64 characters starting with a letter or underscore (_). Only letters, digits, and underscores are allowed. Value: corresponds to the key of the additional attribute of a metric. A maximum of 10 custom dimensions can be added. Example: Set the key to app and value to abc.

      After the parameters are configured, you can click YAML to view the configuration data in YAML format.

5. After the configuration is complete, click Next. The custom Prometheus metrics can then be ingested.
   After ingesting custom Prometheus metrics, you can perform the following operations:

   • Go to the Metric Browsing page to analyze metrics. For details, see Observability Metric Browsing.
   • Go to the Access Management page to view, edit, or delete the configured ingestion rule. For details, see Managing Metric and Log Ingestion.
