Reference documentation and code samples for the BigQuery Migration V2 API class Google::Api::MetricDescriptor.
Defines a metric type and its schema. Once a metric descriptor is created, deleting or altering it stops data collection and makes the metric type's existing data unusable.

#labels
def labels() -> ::Array<::Google::Api::LabelDescriptor>

(::Array<::Google::Api::LabelDescriptor>) — The set of labels that can be used to describe a specific
instance of this metric type. For example, the
appengine.googleapis.com/http/server/response_latencies
metric type has a label for the HTTP response code,response_code
, so you can look at latencies for successful responses or just for responses that failed.

#type
def type() -> ::String
-
(::String) —
The metric type, including its DNS name prefix. The type is not URL-encoded. All user-defined metric types have the DNS name
custom.googleapis.com
orexternal.googleapis.com
. Metric types should use a natural hierarchical grouping. For example:"custom.googleapis.com/invoice/paid/amount" "external.googleapis.com/prometheus/up" "appengine.googleapis.com/http/server/response_latencies"

#unit
def unit() -> ::String
-
(::String) —
The units in which the metric value is reported. It is only applicable if the
value_type
isINT64
,DOUBLE
, orDISTRIBUTION
. Theunit
defines the representation of the stored metric values.Different systems might scale the values to be more easily displayed (so a value of
0.02kBy
might be displayed as20By
, and a value of3523kBy
might be displayed as3.5MBy
). However, if theunit
iskBy
, then the value of the metric is always in thousands of bytes, no matter how it might be displayed.If you want a custom metric to record the exact number of CPU-seconds used by a job, you can create an
INT64 CUMULATIVE
metric whoseunit
iss{CPU}
(or equivalently1s{CPU}
or justs
). If the job uses 12,005 CPU-seconds, then the value is written as12005
.Alternatively, if you want a custom metric to record data in a more granular way, you can create a
DOUBLE CUMULATIVE
metric whoseunit
isks{CPU}
, and then write the value12.005
(which is12005/1000
), or useKis{CPU}
and write11.723
(which is12005/1024

Grammar
The grammar also includes these connectors:
/
division or ratio (as an infix operator). For examples,kBy/{email}
orMiBy/10ms
(although you should almost never have/s
in a metricunit
; rates should always be computed at query time from the underlying cumulative or delta value)..
multiplication or composition (as an infix operator). For examples,GBy.d
ork{watt}.h
.
The grammar for a unit is as follows:
Expression = Component { "." Component } { "/" Component } ; Component = ( [ PREFIX ] UNIT | "%" ) [ Annotation ] | Annotation | "1" ; Annotation = "{" NAME "}" ;
Notes:
Annotation
is just a comment if it follows aUNIT
. If the annotation is used alone, then the unit is equivalent to1
. For examples,{request}/s == 1/s
,By{transmitted}/s == By/s
.NAME
is a sequence of non-blank printable ASCII characters not containing{
or}
.1
represents a unitary dimensionless unit of 1, such as in1/s
. It is typically used when none of the basic units are appropriate. For example, "new users per day" can be represented as1/d
or{new-users}/d
(and a metric value5
would mean "5 new users). Alternatively, "thousands of page views per day" would be represented as1000/d
ork1/d
ork{page_views}/d
(and a metric value of5.3
would mean "5300 page views per day").%
represents dimensionless value of 1/100, and annotates values giving a percentage (so the metric values are typically in the range of 0..100, and a metric value3
means "3 percent").10^2.%
indicates a metric contains a ratio, typically in the range 0..1, that will be multiplied by 100 and displayed as a percentage (so a metric value0.03
means "3 percent").
