Reference documentation and code samples for the Google API Common Protos Client class 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.

string
The metric type, including its DNS name prefix. The type is not URL-encoded. All user-defined metric types have the DNS name |
↳ labels |

The set of labels that can be used to describe a specific instance of this metric type. For example, the |
↳ metric_kind |

Whether the metric records instantaneous values, changes to a value, etc. Some combinations of |
↳ value_type |
int
Whether the measurement is an integer, a floating-point number, etc. Some combinations of |

string
The units in which the metric value is reported. It is only applicable if the |
↳ description |
string
A detailed description of the metric, which can be used in documentation. |
↳ display_name |
string
A concise name for the metric, which can be displayed in user interfaces. Use sentence case without an ending period, for example "Request count". This field is optional but it is recommended to be set for any metrics associated with user-visible concepts, such as Quota. |

Optional. Metadata which can be used to guide usage of the metric. |
↳ launch_stage |
int
Optional. The launch stage of the metric definition. |
↳ monitored_resource_types |
array
Read-only. If present, then a time series, which is identified partially by a metric type and a MonitoredResourceDescriptor, that is associated with this metric type can only be associated with one of the monitored resource types listed here. |

getType
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
or external.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"
Returns | |
---|---|
Type | Description |
string |
setType
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
or external.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"

getLabels
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.

instance of this metric type. For example, the

metric
type has a label for the HTTP response code, response_code
, so
you can look at latencies for successful responses or just

getUnit
The units in which the metric value is reported. It is only applicable
if the value_type
is INT64
, DOUBLE
, or DISTRIBUTION
. The unit
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 as 20By
, and a value of
3523kBy
might be displayed as 3.5MBy
). However, if the unit
is
kBy
, 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 whose unit
is
s{CPU}
(or equivalently 1s{CPU}
or just s
). If the job uses 12,005
CPU-seconds, then the value is written as 12005
.
Alternatively, if you want a custom metric to record data in a more
granular way, you can create a DOUBLE CUMULATIVE
metric whose unit
is
ks{CPU}
, and then write the value 12.005
(which is 12005/1000
),
or use Kis{CPU}
and write 11.723
(which is 12005/1024
).

.NAME

.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").
