Set up Percona Monitoring and Management

Prerequisites

• When deploying Self-Hosted Deployment, you have enabled PMM, that is, you have set the

  enable_percona_monitoring

  setting to true in the Terraform variables file.
• The resources

  ClusterRole

  and

  ClusterRoleBinding

  exist in the Kubernetes cluster.

1. Expose the PMM web interface

1. Create an Ingress resource for the PMM web interface in your Kubernetes cluster.
2. Add a DNS record that points to the PMM service in your DNS provider, for example, Route 53.
3. Ensure that the PMM service is accessible through the configured domain name.

2. Access the PMM web interface

1. Go to the PMM web interface using your configured domain name.
2. Sign in with the

   admin

   username. To retrieve the password, run this command:

   kubectl get secret pmm-admin-password -o jsonpath="{.data.GF_SECURITY_ADMIN_PASSWORD}" | base64 --decode

3. Create a token to integrate PSMDB with PMM

1. In the PMM web interface, go to Administration > Service Accounts.
2. Select Add Service Account.
3. Enter a descriptive name for the service account, choose Admin role and then select Create.
4. Select Add service account Token.
5. Copy the generated API key, and then save it to a secure location.
6. Update the Terraform variable

   psmdb_pmm_server_token

   with the API key in your configuration file.
   The entry must have this format:

   psmdb_pmm_server_token = "<YOUR_PMM_TOKEN>"

7. To apply the changes, run this command:

   cd aws/terraformmake apply-us-east-1

4. Validate the metrics collection

1. Ensure that there are no access errors. To check the PSMDB pod logs, run this command:

   kubectl logs psmdb-db-rs0-0 -c pmm-client

2. To verify that the metrics are being collected in the PMM web interface, consult the MongoDB metrics in the MongoDB section.
