DataDogCounters

Inherits: CachedCounters, IReferenceable, IOpenable

Description

The DataDogCounters class allows you to create performance counters that send their metrics to a DataDog service.

Configuration parameters

• connection(s):
  • discovery_key: (optional) key to retrieve the connection from IDiscovery
    • protocol: (optional) connection protocol: http or https (default: https)
    • host: (optional) host name or IP address (default: api.datadoghq.com)
    • port: (optional) port number (default: 443)
    • uri: (optional) resource URI or connection string with all parameters in it
• credential:
  • access_key: DataDog client api key
• options:
  • retries: number of retries (default: 3)
  • connect_timeout: connection timeout in milliseconds (default: 10 sec)
  • timeout: invocation timeout in milliseconds (default: 10 sec)

References

• *:logger:*:*:1.0 - (optional) ILogger components to pass log messages.
• *:counters:*:*:1.0 - (optional) ICounters components to pass collected measurements.
• *:discovery:*:*:1.0 - (optional) IDiscovery services to resolve connections.

Constructors

Creates a new instance of the class.

public DataDogCounters()

Instance methods

CloseAsync

Closes a component and frees used resources.

public Task CloseAsync(IContext context)

• context: IContext - (optional) a context to trace execution through a call chain.

Configure

Configures a component by passing its configuration parameters.

public override void Configure(ConfigParams config)

• config: ConfigParams - (optional) transaction id used to trace execution through the call chain.

IsOpen

Checks if the component is open.

public bool IsOpen()

• returns: bool - true if the component is open and false otherwise.

Open

Opens the component.

public Task OpenAsync(IContext context)

• context: IContext - (optional) a context to trace execution through a call chain.

Save

Saves the current counters' measurements.

protected override void Save(IEnumerable<Counter> counters)

• counters: IEnumerable<Counter> - current counters' measurements to be saved.

SetReferences

Sets references to dependent components.

public void SetReferences(IReferences references)

• references: IReferences - references to locate the component’s dependencies.

Examples

var counters = new DataDogCounters();
counters.Configure(ConfigParams.FromTuples(
    "credential.access_key", "827349874395872349875493"
));
await counters.OpenAsync("123");

counters.Increment("mycomponent.mymethod.calls");
let timing = counters.BeginTiming("mycomponent.mymethod.exec_time");
try {
    ...
} finally {
    timing.EndTiming();
}
counters.Dump();
