Network Load Balancer Metrics

Describes how to set up and use metrics to measure the number and type of connections, and quantity of data managed by your network load balancer.

Network Load Balancer service metrics help you monitor the number and type of connections, and quantity of traffic processed by your network load balancer. You can use metrics data to diagnose and troubleshoot network load balancer and client issues.

To view a default set of metrics charts in the OCI Console, navigate to the network load balancer or backend set you are interested in, and then click Metrics. You also can use the Monitoring service to create custom queries.

To view metrics from the OCI Console:

  1. Open the navigation menu, click Networking, and then click Load Balancers.

  2. Select the Compartment from the list.

    All load balancers and network load balancers in that compartment are listed in tabular form.

  3. (optional) Select a State from the list to limit the load balancers displayed to that state.

  4. (optional) Uncheck Load Balancer under Type to only display network load balancers.

  5. Select the network load balancer whose metrics you want to view.

    The Details dialog box appears.

  6. Click Metrics under Resources.

    The Metrics section appears.

    You can specify the start and end time periods for which the metrics apply. You can also select various commands and view types from the Options list.

Prerequisites

  • IAM policies: To monitor resources, you must be given the required type of access in a policy  written by an administrator, whether you're using the Console or the REST API with an SDK, CLI, or other tool. The policy must give you access to the monitoring services as well as the resources being monitored. If you try to perform an action and get a message that you don’t have permission or are unauthorized, confirm with your administrator the type of access you've been granted and which compartment  you should work in. For more information about user authorizations for monitoring, see IAM Policies (Monitoring).
  • The metrics listed on this page are automatically available for any load balancer, listener, and backend set you create. You do not need to enable monitoring on the resource to get these metrics.
