Interface IDriverMetricsProvider

Provides metric implementations.

Namespace: Dse.Metrics.Abstractions

Assembly: Dse.dll

Syntax

public interface IDriverMetricsProvider

Methods

Counter(String, IMetric)

Creates a counter metric. bucket will contain the prefix configured with SetBucketPrefix(String), session name and node's address. Node's address will only be in the bucket name when metric is a NodeMetric. Implementations can call System.Object.Equals(System.Object) to test if metric is a particular NodeMetric or SessionMetric.

Declaration

IDriverCounter Counter(string bucket, IMetric metric)

Parameters

Type	Name	Description
System.String	bucket
IMetric	metric

Returns

Type	Description
IDriverCounter

Gauge(String, IMetric, Func<Nullable<Double>>)

Creates a gauge metric. bucket will contain the prefix configured with SetBucketPrefix(String), session name and node's address. Node's address will only be in the bucket name when metric is a NodeMetric. Implementations can call System.Object.Equals(System.Object) to test if metric is a particular NodeMetric or SessionMetric.

Declaration

IDriverGauge Gauge(string bucket, IMetric metric, Func<double?> valueProvider)

Parameters

Type	Name	Description
System.String	bucket
IMetric	metric
System.Func<System.Nullable<System.Double>>	valueProvider

Returns

Type	Description
IDriverGauge

Meter(String, IMetric)

Creates a meter metric. bucket will contain the prefix configured with SetBucketPrefix(String), session name and node's address. Node's address will only be in the bucket name when metric is a NodeMetric. Implementations can call System.Object.Equals(System.Object) to test if metric is a particular NodeMetric or SessionMetric.

Declaration

IDriverMeter Meter(string bucket, IMetric metric)

Parameters

Type	Name	Description
System.String	bucket
IMetric	metric

Returns

Type	Description
IDriverMeter

ShutdownMetricsBucket(String)

Shutdowns/Disposes metrics created with the provided bucket. This is especially useful to stop gauges which are supposed to run on a loop.

Declaration

void ShutdownMetricsBucket(string bucket)

Parameters

Type	Name	Description
System.String	bucket

Timer(String, IMetric)

Creates a timer metric. bucket will contain the prefix configured with SetBucketPrefix(String), session name and node's address. Node's address will only be in the bucket name when metric is a NodeMetric. Implementations can call System.Object.Equals(System.Object) to test if metric is a particular NodeMetric or SessionMetric.

Declaration

IDriverTimer Timer(string bucket, IMetric metric)

Parameters

Type	Name	Description
System.String	bucket
IMetric	metric

Returns

Type	Description
IDriverTimer
