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
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:

Backend latency
A distribution of the latency calculated from when the request was sent by the proxy to the backend until the proxy received from the backend the last byte of response. For Service Extensions, this value represents the sum of latencies of each ProcessingRequest/ProcessingResponse pair between the load balancer and the extension backend. Sampled every 60 seconds. After sampling, data is not visible for up to 210 seconds.
