Description
metric_name [required]
string

Chaînes de requête

Name
Type
Description
filter[groups]
string

Comma-separated list of tag keys that the metric is configured to query with. For example: filter[groups]=app,host.

filter[exclude_tags_mode]
boolean

When true, filter[groups] is treated as an exclude list instead of an include list. Defaults to false.

filter[hours_ago]
integer

The number of hours of look back (from now) to estimate cardinality with. If unspecified, it defaults to 0 hours.

filter[num_aggregations]
integer

Deprecated. Number of aggregations has no impact on volume.

filter[pct]
boolean

Deprecated. This query parameter has no effect on the estimate.

filter[timespan_h]
integer

A window, in hours, from the look back to estimate cardinality with. The minimum and default is 1 hour.

Réponse

Success

Response object that includes metric cardinality estimates.
