Reference documentation and code samples for the Cloud Logging V2 API class Google::Cloud::Logging::V2::LogMetric.
Describes a logs-based metric. The value of the metric is the number of log entries that match a logs filter in a given time interval.
Logs-based metrics can also be used to extract values from logs and create a distribution of the values. The distribution records the statistics of the extracted values along with an optional histogram of the values as specified by the bucket options.

-
(::Google::Protobuf::Map{::String => ::String}) — Optional. A map from a label key string to an extractor expression which is
used to extract data from a log entry field and assign as the label value.
Each label key specified in the LabelDescriptor must have an associated
extractor expression in this map. The syntax of the extractor expression
is the same as for the
value_extractor
field.The extracted value is converted to the type defined in the label descriptor. If either the extraction or the type conversion fails, the label will have a default value. The default value for a string label is an empty string, for an integer label its 0, and for a boolean label its
false
.Note that there are upper bounds on the maximum number of labels and the number of active time series that are allowed in a project.

#metric_descriptor
def metric_descriptor() -> ::Google::Api::MetricDescriptor
-
(::Google::Api::MetricDescriptor) — Optional. The metric descriptor associated with the logs-based metric.
If unspecified, it uses a default metric descriptor with a DELTA metric
kind, INT64 value type, with no labels and a unit of "1". Such a metric
counts the number of log entries matching the
filter
expression.The
name
,type
, anddescription
fields in themetric_descriptor
are output only, and is constructed using thename
anddescription
field in the LogMetric.To create a logs-based metric that records a distribution of log values, a DELTA metric kind with a DISTRIBUTION value type must be used along with a
value_extractor
expression in the LogMetric.Each label in the metric descriptor must have a matching label name as the key and an extractor expression as the value in the
label_extractors
map.The
metric_kind
andvalue_type
fields in themetric_descriptor
cannot be updated once initially configured. New labels can be added in themetric_descriptor
, but existing labels cannot be modified except for their description.

#name
def name() -> ::String
-

,"nginx/requests"
.Metric identifiers are limited to 100 characters and can include only the following characters:
A-Z
,a-z

#update_time
def update_time() -> ::Google::Protobuf::Timestamp
-
(::Google::Protobuf::Timestamp) — Output only. The last update timestamp of the metric.
This field may not be present for older metrics.
#value_extractor
def value_extractor() -> ::String
-
(::String) — Optional. A
value_extractor
is required when using a distribution logs-based metric to extract the values to record from a log entry. Two functions are supported for value extraction:EXTRACT(field)
orREGEXP_EXTRACT(field, regex)
. The arguments are:- field: The name of the log entry field from which the value is to be extracted.
- regex: A regular expression using the Google RE2 syntax (https://github.com/google/re2/wiki/Syntax) with a single capture group to extract data from the specified log entry field. The value of the field is converted to a string before applying the regex. It is an error to specify a regex that does not include exactly one capture group.
The result of the extraction must be convertible to a double type, as the distribution always records double values. If either the extraction or the conversion to double fails, then those values are not recorded in the distribution.
Example:
REGEXP_EXTRACT(jsonPayload.request, ".*quantity=(\d+).*")
