You can monitor the performance and health of your Google Cloud load-balanced applications and services using metrics provided by Cloud Monitoring. These metrics represent collections of measurements that help you maintain optimal operations. In Cloud Monitoring, each service or component under observation is called a monitored resource.
Use the following resources to find details about supported metric types, units used, and their metadata:
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
unitfield in theMetricDescriptorreference.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/ |
Global external Application Load Balancer Classic Application Load Balancer |
https/external/regional |
Regional external Application Load Balancer |
https/internal/ |
Cross-region internal Application Load Balancer Regional internal Application Load Balancer |
l3/external/ |
External passthrough Network Load Balancer |

tcp_ssl_proxy/ |
Classic proxy Network Load Balancer |
l4_proxy/ |
Global external proxy Network Load Balancer Cross-region internal proxy Network Load Balancer Regional internal proxy Network Load Balancer Regional external 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".
