Reporting Self-Built Prometheus Instance Data to AOM

Prerequisites

• You have purchased an ECS.
• Your service has been connected for Prometheus monitoring. For more details, see:
  • Prometheus Instance for ECS
  • Prometheus Instance for CCE
  • Common Prometheus Instance

Procedure

1. Install and start Prometheus. For details, see Prometheus official documentation.
2. Add an access code.
   1. Log in to the AOM 2.0 console.
   2. In the navigation pane, choose Settings. The Global Configuration page is displayed.
   3. In the navigation pane on the left, choose Authentication. Click Add Access Code.
   4. In the dialog box that is displayed, click OK. The system then automatically generates an access code.
   

   • You can create up to two access codes for each project.
   • An access code is an identity credential for calling APIs. Keep your access code secure.

3. Obtain the configuration code for Prometheus remote write.
   1. Log in to the AOM 2.0 console.
   2. In the navigation pane on the left, choose Prometheus Monitoring > Instances. In the instance list, click the target Prometheus instance.
   3. On the displayed page, choose Settings in the navigation pane and obtain the configuration code for Prometheus remote write from the Service Addresses area.
      Figure 1 Configuration code for Prometheus remote write
      

4. Log in to the target ECS and configure the prometheus.yml file.

   Run the following command to find and start the prometheus.yml file:

   ./prometheus --config.file=prometheus.yml

   Add the configuration code for Prometheus remote write obtained in 3 to the end of the prometheus.yml file.

   The following shows an example. You need to configure the italic part.

   # my global config
   global:
   scrape_interval:     15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
   evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
   # scrape_timeout is set to the global default (10s).
   
   # Alertmanager configuration
   alerting:
   alertmanagers:
     - static_configs:
     - targets:
   # - alertmanager:9093
   
   # Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
   rule_files:
   # - "first_rules.yml"
   # - "second_rules.yml"
   
   # A scrape configuration containing exactly one endpoint to scrape:
   # Here it's Prometheus itself.
   scrape_configs:
   # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
     - job_name: 'prometheus'
   
   # metrics_path defaults to '/metrics'
   # scheme defaults to 'http'.
   
   static_configs:
     - targets: ['localhost:9090']
   # Replace the italic content with the configuration code for Prometheus remote write obtained in 3.
   remote_write:
     - url:'https://aom-**.***.myhuaweicloud.com:8443/v1/6d6df***2ab7/58d6***c3d/push'
       tls_config:
         insecure_skip_verify: true
       bearer_token: 'SE**iH'

5. Check the private domain name.

   In the preceding example, data is reported through the intranet. Therefore, ensure that the host where Prometheus is located can resolve the private domain name. For details, see Changing the DNS Server Addresses for a VPC Subnet.

6. Restart Prometheus.
7. View metric data in AOM using Grafana to check whether data is successfully reported after the preceding configurations are modified.
