Export Metrics From a CockroachDB Dedicated Cluster

Exporting metrics to AWS CloudWatch is only available on CockroachDB Dedicated clusters that are hosted on AWS. If your CockroachDB Dedicated cluster is hosted on Azure, you can export metrics to Azure Monitor. If your CockroachDB Dedicated cluster is hosted on GCP, you can export metrics to Datadog or Prometheus instead.

Perform the following steps to enable metrics export from your CockroachDB Dedicated cluster to AWS CloudWatch.

1. Create the desired target AWS CloudWatch log group by following the Create a log group in CloudWatch instructions. If you already have a log group created, you may skip this step. When your CockroachDB Dedicated cluster emits metrics to AWS CloudWatch, they are written to this log group.

2. Find your CockroachDB Dedicated cluster ID:

   1. Visit the CockroachDB Cloud console cluster page.
   2. Click on the name of your cluster.
   3. Find your cluster ID in the URL of the single cluster overview page: https://cockroachlabs.cloud/cluster/{your_cluster_id}/overview. The ID should resemble f78b7feb-b6cf-4396-9d7f-494982d7d81e.

3. Determine your cluster's cloud provider account ID. This command uses the third-party JSON parsing tool jq to isolate just the needed account_id field:

   curl --request GET \
     --url https://cockroachlabs.cloud/api/v1/clusters/{your_cluster_id} \
     --header 'Authorization: Bearer {secret_key}' | jq .account_id
   

   Where:

   • {your_cluster_id} is the cluster ID of your CockroachDB Dedicated cluster as determined in step 2.
   • {secret_key} is your CockroachDB Dedicated API key. See API Access for more details.

4. Create a cross-account IAM role in your AWS account:

   1. In the AWS console, visit the IAM page.
   2. Select Roles and click Create role.
   3. For Trusted entity type, select AWS account.
   4. Choose Another AWS account.
   5. For Account ID, provide the CockroachDB Dedicated cloud provider account ID from step 3.
   6. Finish creating the IAM role with a suitable name. These instructions will use the role name CockroachCloudMetricsExportRole. You do not need to add any permissions.
   Note:

   You will need the Amazon Resource Name (ARN) for your cross-account IAM role later in this procedure.

5. Select the new role, and create a new policy for this role. These instructions will use the policy name CockroachCloudMetricsExportPolicy.

6. Select the new policy, and paste the following into the Permissions tab, with the {} JSON option selected:

   {
       "Version": "2012-10-17",
       "Statement": [
           {
               "Action": [
                   "logs:CreateLogGroup",
                   "logs:CreateLogStream",
                   "logs:DescribeLogGroups",
                   "logs:DescribeLogStreams",
                   "logs:PutRetentionPolicy",
                   "logs:PutLogEvents"
               ],
               "Effect": "Allow",
               "Resource": [
                   "arn:aws:logs:*:{your_aws_acct_id}:log-group:{log_group_name}",
                   "arn:aws:logs:*:{your_aws_acct_id}:log-group:{log_group_name}:log-stream:*"
               ]
           }
       ]
   }
   

   Where:

   • {your_aws_acct_id} is the AWS Account ID of the AWS account where you created the CockroachCloudMetricsExportRole role, not the cloud provider account ID of your CockroachDB Dedicated cluster from step 3. You can find your AWS Account ID on the AWS IAM page.
   • {log_group_name} is the target AWS CloudWatch log group you created in step 1.

   This defines the set of permissions that the CockroachDB Dedicated metrics export feature requires to be able to write metrics to CloudWatch.

7. Copy the Amazon Resource Name (ARN) of the CockroachCloudMetricsExportRole role found under Summary, which is needed for the next step.

8. Issue the following Cloud API command to enable metrics export for your CockroachDB Dedicated cluster:

   curl --request POST \
     --url https://cockroachlabs.cloud/api/v1/clusters/{cluster_id}/metricexport/cloudwatch \
     --header "Authorization: Bearer {secret_key}" \
     --data '{"target_region": "{aws_region}", "role_arn": "arn:aws:iam::{role_arn}:role/CockroachCloudMetricsExportRole", "log_group_name": "{log_group_name}"}'
   

   Where:

   • {cluster_id} is your CockroachDB Dedicated cluster ID as determined in step 2.
   • {secret_key} is your CockroachDB Dedicated API key. See API Access for instructions on generating this key.
   • {aws_region} is your AWS region, like us-east-1.
   • {role_arn} is the ARN for the CockroachCloudMetricsExportRole role you copied in step 7. If you used a different role name there, be sure to use your role name in place of CockroachCloudMetricsExportRole in the above command.
   • {log_group_name} is the target AWS CloudWatch log group you created in step 1. This must be the same group name you provided in step 6.

   Specifying an AWS region (to {aws_region}) that you do not have a cluster in, or a region that only partially covers your cluster's nodes will result in missing metrics.

9. Depending on the size of your cluster and how many regions it spans, the configuration may take a moment. You can monitor the ongoing status of the configuration using the following Cloud API command:

   curl --request GET \
     --url https://cockroachlabs.cloud/api/v1/clusters/{cluster_id}/metricexport/cloudwatch \
     --header "Authorization: Bearer {secret_key}"
   

   Run the command periodically until the command returns a status of ENABLED, at which point the configuration across all nodes is complete, and metrics will begin appearing in CloudWatch under the log group you created in step 1. Since the configuration is applied to cluster nodes in a rolling fashion, you may see some metrics appear even before the GET command returns an ENABLED status.

10. Once metrics export has been enabled, you can access metrics from your CockroachDB Dedicated cluster directly in AWS CloudWatch.

To enable metrics export for your CockroachDB Dedicated cluster to Datadog, you can either enable the Datadog integration in your CockroachDB Dedicated Cloud Console, or on the command line via the Cloud API:

• To enable metrics export to Datadog using the Cloud Console, follow the Monitor CockroachDB Dedicated with Datadog instructions.
• To enable metrics export to Datadog using the Cloud API, follow the steps below.

1. Find your CockroachDB Dedicated cluster ID:

   1. Visit the CockroachDB Cloud console cluster page.
   2. Click on the name of your cluster.
   3. Find your cluster ID in the URL of the single cluster overview page: https://cockroachlabs.cloud/cluster/{your_cluster_id}/overview. The ID should resemble f78b7feb-b6cf-4396-9d7f-494982d7d81e.

2. Determine the Datadog API key you'd like to use. If you don't already have one, follow the steps to add a new Datadog API key.

3. Issue the following Cloud API command to enable metrics export for your CockroachDB Dedicated cluster:

   curl --request POST \
     --url https://cockroachlabs.cloud/api/v1/clusters/{cluster_id}/metricexport/datadog \
     --header "Authorization: Bearer {secret_key}" \
     --data '{"site": "{datadog_site}", "api_key": "{datadog_api_key}"}'
   

   Where:

   • {cluster_id} is your CockroachDB Dedicated cluster ID as determined in step 1, resembling f78b7feb-b6cf-4396-9d7f-494982d7d81e.
   • {secret_key} is your CockroachDB Dedicated API key. See API Access for instructions on generating this key.
   • {datadog_site} is your Datadog site. Valid sites are: US1, US3, US5, US1_GOV, and EU1.
   • {datadog_api_key} is the Datadog API key determined in step 2.

4. Depending on the size of your cluster and how many regions it spans, the configuration may take a moment. You can monitor the ongoing status of the configuration using the following Cloud API command:

   curl --request GET \
     --url https://cockroachlabs.cloud/api/v1/clusters/{cluster_id}/metricexport/datadog \
     --header "Authorization: Bearer {secret_key}"
   

   Run the command periodically until the command returns a status of ENABLED, at which point the configuration across all nodes is complete, and metrics will begin appearing in the Datadog interface. Since the configuration is applied to cluster nodes in a rolling fashion, you may see some metrics appear even before the GET command returns an ENABLED status.

5. Once metrics export has been enabled, you can access metrics from your CockroachDB Dedicated cluster directly in Datadog's Metrics Explorer, or via Datadog's notebook or dashboard features.

6. Review enable percentiles for selected metrics. Configure metrics as necessary.

1. Find your CockroachDB Dedicated cluster ID:

   1. Visit the CockroachDB Cloud console cluster page.
   2. Click on the name of your cluster.
   3. Find your cluster ID in the URL of the single cluster overview page: https://cockroachlabs.cloud/cluster/{your_cluster_id}/overview. The ID should resemble f78b7feb-b6cf-4396-9d7f-494982d7d81e.

2. Issue the following Cloud API command to enable metrics export for your CockroachDB Dedicated cluster:

   curl --request POST \
     --url https://cockroachlabs.cloud/api/v1/clusters/{cluster_id}/metricexport/prometheus \
     --header "Authorization: Bearer {secret_key}"
   

   Where:

   • {cluster_id} is your CockroachDB Dedicated cluster ID as determined in step 1, resembling f78b7feb-b6cf-4396-9d7f-494982d7d81e.
   • {secret_key} is your CockroachDB Dedicated API key. See API Access for instructions on generating this key.

3. Depending on the size of your cluster and how many regions it spans, the configuration may take a moment. You can monitor the ongoing status of the configuration using the following Cloud API command:

   curl --request GET \
     --url https://cockroachlabs.cloud/api/v1/clusters/{cluster_id}/metricexport/prometheus \
     --header "Authorization: Bearer {secret_key}"
   

   Run the command periodically until the command returns a status of ENABLED, at which point the configuration across all nodes is complete. The response also includes targets, a map of scrape endpoints exposing metrics to regions. For example:

   {
     "cluster_id": "f78b7feb-b6cf-4396-9d7f-494982d7d81e",
     "user_message": "This integration is active.",
     "status": "ENABLED",
     "targets": {
       "us-east4": "https://cockroachlabs.cloud/api/v1/clusters/f78b7feb-b6cf-4396-9d7f-494982d7d81e/metricexport/prometheus/us-east4/scrape"
     }
   }
   

   There is a separate scrape endpoint per region if you have a multi-region cluster.

4. You can test a scrape endpoint by using the following Cloud API command:

   curl --request GET \
     --url https://cockroachlabs.cloud/api/v1/clusters/{cluster_id}/metricexport/prometheus/{cluster_region}/scrape \
     --header "Authorization: Bearer {secret_key}"
   

   Where:

   • {cluster_id} is your CockroachDB Dedicated cluster ID as determined in step 1, resembling f78b7feb-b6cf-4396-9d7f-494982d7d81e.
   • {cluster_region} is a region of your CockroachDB Dedicated cluster as shown in the targets of step 3, such as us-east4. You can also find your cluster’s region(s) on the Cluster Overview page.
   • {secret_key} is your CockroachDB Dedicated API key. See API Access for instructions on generating this key.

   Metrics are labeled with the cluster name and ID, node, organization name, and region. The beginning lines of a metrics scrape response follows:

   # HELP crdb_dedicated_addsstable_applications Number of SSTable ingestions applied (i.e. applied by Replicas)
   # TYPE crdb_dedicated_addsstable_applications counter
   crdb_dedicated_addsstable_applications{cluster="test-gcp",instance="172.28.0.167:8080",node="cockroachdb-j5t6j",node_id="1",organization="CRL - Test",region="us-east4",store="1"} 0

5. Once metrics export has been enabled and the scrape endpoint(s) tested, you need to configure your metrics collector to periodically poll the scrape endpoint(s). Configure your Prometheus configuration file's scrape_configs section as in the following example:

   global:
     scrape_interval: 10s
     evaluation_interval: 10s
   
   # Prometheus configuration for CockroachDB Dedicated for a single region
   scrape_configs:
     - job_name: '{job_name}'
       metrics_path: '/api/v1/clusters/{cluster_id}/metricexport/prometheus/{cluster_region}/scrape'
       static_configs:
         - targets: ['cockroachlabs.cloud']
       scheme: 'https'
       authorization:
         credentials: '{secret_key}'
