Serilog.Sinks.Datadog.Logs 0.3.0

Serilog.Sinks.Datadog.Logs

A Serilog sink that send events and logs staight away to Datadog. By default the sink sends logs over HTTPS

Package - Serilog.Sinks.Datadog.Logs | Platforms - .NET 4.5.1, netstandard1.3, netstandard2.0

Note: For other .NET versions, ensure that the default TLS version used is 1.2

var log = new LoggerConfiguration()
    .WriteTo.DatadogLogs("<API_KEY>")
    .CreateLogger();

By default the logs are forwarded to Datadog via HTTPS on port 443 to the US site. You can change the site to EU by using the url property and set it to https://http-intake.logs.datadoghq.eu.

You can override the default behavior and use TCP forwarding by manually specifing the following properties (url, port, useSSL, useTCP).

You can also add the following properties (source, service, host, tags) to the Serilog sink.

• Example with a TCP forwarder which add the source, service, host and a list of tags to the logs:

var config = new DatadogConfiguration(url: "intake.logs.datadoghq.com", port: 10516, useSSL: true, useTCP: true);
var log = new LoggerConfiguration()
    .WriteTo.DatadogLogs(
        "<API_KEY>",
        source: "<SOURCE_NAME>",
        service: "<SERVICE_NAME>",
        host: "<HOST_NAME>",
        tags: new string[] {"<TAG_1>:<VALUE_1>", "<TAG_2>:<VALUE_2>"},
        configuration: config
    )
    .CreateLogger();

Example

Sending the following log:

var log = new LoggerConfiguration()
    .WriteTo.DatadogLogs("<API_KEY>")
    .CreateLogger();

// An example
var position = new { Latitude = 25, Longitude = 134 };
var elapsedMs = 34;

log.Information("Processed {@Position} in {Elapsed:000} ms.", position, elapsedMs);

In the platform, the log looks like as the following JSON Object:

{
    "MessageTemplate": "Processed {@Position} in {Elapsed:000} ms.",
    "Level": "Information",
    "Timestamp": "2016-09-02T15:02:29.648Z",
    "Renderings": {
        "Elapsed": [{
            "Format": "000",
            "Rendering": "034"
        }]
    },
    "Properties": {
        "Position": {
            "Latitude": 25,
            "Longitude": 134
        },
        "Elapsed": 34
    }
}

Configuration from appsettings.json

Since 0.2.0, you can configure the Datadog sink by using an appsettings.json file with the Serilog.Setting.Configuration package.

In the "Serilog.WriteTo" array, add an entry for DatadogLogs. An example is shown below:

"Serilog": {
  "Using": [ "Serilog.Sinks.Console", "Serilog.Sinks.Datadog.Logs" ],
  "MinimumLevel": "Debug",
  "WriteTo": [
    { "Name": "Console" },
    {
      "Name": "DatadogLogs",
      "Args": {
        "apiKey": "<API_KEY>",
        "source": "<SOURCE_NAME>",
        "host": "<HOST_NAME>",
        "tags": ["<TAG_1>:<VALUE_1>", "<TAG_2>:<VALUE_2>"],
      }
    }
  ],
  "Enrich": [ "FromLogContext", "WithMachineName", "WithThreadId" ],
  "Properties": {
    "Application": "Sample"
  }
}
