Network Load Balancer Metrics
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 Oracle Cloud Infrastructure Console, navigate to the network load balancer or backend set you are interested in, and then click Metrics.
You can use the Oracle Cloud Infrastructure Monitoring service to create custom queries. Use the information contained in this topic for setting up monitoring. See Monitoring for more information.
Prerequisites
- IAM policies: To monitor resources, you must be granted 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, contact the administrator to determine the type of access you were granted and which compartment you need to 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.
Available Metrics: oci_nlb
Network Load Balancer metrics include the following dimensions :- RESOURCEID
- The OCID of the network load balancer resource to which the metrics apply.
- RESOURCENAME
- The display name of the network load balancer resource to which the metrics apply.
