Load balancing metrics

Cloud Monitoring collects measurements to help you understand how your applications and system services are performing. A collection of these measurements is generically called a metric. The applications and system services being monitored are called monitored resources.

  • For a general explanation of the entries in the tables, see Metric types.

  • For information about the units used in the metric lists, see the unit field in the MetricDescriptor reference.

  • For information about statements of the form “Sampled every x seconds” and “After sampling, data is not visible for up to y seconds”, see Additional information: metadata.

  • For a set of complete, current lists of supported metric types, see Metrics list.

  • For pricing information, see Monitoring pricing.

The following table maps metric path prefixes to the load balancer types:

Metric path Load balancer
https/ External Application Load Balancer
https/external/regional Regional external Application Load Balancer
https/internal/ Internal Application Load Balancer
l3/external/ External passthrough Network Load Balancer
l3/internal/ Internal passthrough Network Load Balancer
tcp_ssl_proxy/ External proxy Network Load Balancer
l4_proxy/ Regional internal proxy Network Load Balancer

The "metric type" strings in this table must be prefixed with loadbalancing.googleapis.com/. That prefix has been omitted from the entries in the table. When querying a label, use the metric.labels. prefix; for example, metric.labels.LABEL="VALUE".
