Cloud Monitoring supports the Knative metrics listed in this document.
For a general explanation of the entries in the tables, including information about values like
DELTA
andGAUGE
, see Metric types.To chart or monitor metric types with values of type
STRING
, you must use Monitoring Query Language (MQL), and you must convert the value into a numeric value. For information about MQL string-conversion methods, seeString
.
- For information about the units used in the metric lists, see
the
unit
field in theMetricDescriptor
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 pricing information, see Cloud Monitoring pricing summary.
- For information about the meaning of launch stages such as
GA
(General Availability) andBETA
(Preview), see Product launch stages.

Description Labels |
serving/activator/request_count
BETA
Activator Request Count |
|
DELTA , INT64 , 1
knative_revision |
The number of requests that are routed to the activator. Sampled every 60 seconds. After sampling, data is not visible for up to 180 seconds.
response_code_class :
One of '1xx', '2xx', '3xx', '4xx', or '5xx' according to response code of the request. If any other code is returned, it should be reported as '5xx'.
response_code :
(INT64)
Response code of the request according to protocol.
num_tries :
(INT64)
The number of tries (retry on 503s only) it takes to get a response from a reserve revision.

DELTA , DISTRIBUTION , ms
knative_revision |
Distribution of service request times in milliseconds for requests that go through the activator. Value is the total time requests spent in activator and revision pods. Sampled every 60 seconds. After sampling, data is not visible for up to 180 seconds.
response_code_class :
One of '1xx', '2xx', '3xx', '4xx', or '5xx' according to response code of the request. If any other code is returned, it should be reported as '5xx'.
