include METRIC
A collection of metrics that are the same except for their labels. e.g. "Number of HTTP responses"
val v_labels :
label_names:string list ->
?registry:CollectorRegistry.t ->
help:string ->
?namespace:string ->
?subsystem:string ->
string ->
familyv_labels ~label_names ~help ~namespace ~subsystem name is a family of metrics with full name namespace_subsystem_name and documentation string help. Each metric in the family will provide a value for each of the labels. The new family is registered with registry (default: CollectorRegistry.default).
labels family label_values is the metric in family with these values for the labels. The order of the values must be the same as the order of the label_names passed to v_labels; you may wish to write a wrapper function with labelled arguments to avoid mistakes. If this is called multiple times with the same set of values, the existing metric will be returned.
val v_label :
label_name:string ->
?registry:CollectorRegistry.t ->
help:string ->
?namespace:string ->
?subsystem:string ->
string ->
string ->
tv_label is a convenience wrapper around v_labels for the case where there is a single label. The result is a function from the single label's value to the metric.
val v :
?registry:CollectorRegistry.t ->
help:string ->
?namespace:string ->
?subsystem:string ->
string ->
tv is a convenience wrapper around v_labels for the case where there are no labels.
val observe : t -> float -> unitobserve t v adds one to the appropriate bucket for v and adds v to the sum.
