Monitoring Managed kdb cluster metrics

You can monitor the health and activity of Managed kdb Insights clusters by using CloudWatch. When you interact with Managed kdb clusters, the following metrics are sent to CloudWatch in the AWS account that you used to create the Managed kdb environment. You can use the following procedures to view the metrics for Managed kdb clusters.

To view metrics using the CloudWatch console

Metrics are grouped first by the service namespace, and then by the various dimension combinations within each namespace.

1. Open the CloudWatch console at https://console.aws.amazon.com/cloudwatch/.

2. In the navigation pane, choose Metrics.

3. Under the All metrics tab, choose FinSpace and then choose the KxClusterId.

Logging

The KDB application logs from Managed kdb clusters are captured in Amazon CloudWatch Logs. There is a separate CloudWatch Log Group created for each cluster. You can access cluster logs for FinSpace in the following CloudWatch log group.

/aws/vendedlogs/finspace/<Managed kdb Environment ID>/<Managed kdb Cluster Name>

You can view data directly in CloudWatch using CloudWatch reporting or CloudWatch Insights. You can also extract the data from CloudWatch into other logging tools like Splunk or Datadog. Using the Logs, you can view stdout and stderr logs the for KDB processes. From this tab, you can navigate to CloudWatch Logs Insights to run custom queries on the logs.

To view and query logs for Managed kdb clusters

1. Sign in to the AWS Management Console and open the Amazon FinSpace console at https://console.aws.amazon.com/finspace.

2. In the left pane, under Managed kdb Insights, choose Kdb environments.

3. From the kdb environments table, choose the name of the environment.

4. On the environment details page, choose the Clusters tab. The table under this tab displays a list of clusters.

5. Choose a cluster name to view its logs. The cluster details page opens.

6. Choose the Logs tab. The logs are displayed in a list.

7. Choose the @logstream links to open the CloudWatch Logs Insights where you can run custom queries on the logs.
