ThiagoBarradas/serilog-sinks-newrelic-logs

A Serilog sink that writes events to the NewRelic Logs.

Getting started

Log.Logger = new LoggerConfiguration()
    .WriteTo.NewRelicLogs(
        endpointUrl: "https://log-api.newrelic.com/log/v1", 
        applicationName: "Serilog.Sinks.NewRelic.Sample", 
        licenseKey: "[Your API key]")
    .CreateLogger();

If you have new relic agent and use environment variables NEW_RELIC_APP_NAME and NEW_RELIC_LICENSE_KEY, you can do just:

Log.Logger = new LoggerConfiguration()
    .WriteTo.NewRelicLogs()
    .CreateLogger();

The available parameters are:

applicationName of the current application in NewRelic If the parameter is omitted, then the value of the "NewRelic.AppName" appSetting will be used.
endpointUrl is the ingestion URL of NewRelic Logs. The US endpoint is used by default if this value is omitted.
licenseKey is the NewRelic License key, which is also used with the NewRelic Agent.
insertKey is New Relic Insert API key. Either licenseKey or insertKey must be supplied.

The events are submitted to NewRelic Logs in batches, and the sink is derived from PeriodicBatchingSink. It therefore supports the following parameter:

batchSizeLimit is the maximum number of events to include in a single batch. Default is 1000 entries
period is the time to wait between checking for event batches. It is TimeSpan with a default value of 2 seconds. If provided from AppSettings, the value should be given as an absolute time span, i.e.: "0.00:00:05" standing for 5 seconds.

The batches are formatted using NewRelic Logs detailed JSON body and are transmitted GZip-compressed.

All properties along with the rendered message will be emitted to NewRelic Logs. This sink adds four additional properties:

timestamp in milliseconds since epoch
application holds the value from applicationName
level is the actual log level of the event.
stack_trace holds the stack trace portion of an exception.
exception holds the .toString() of an exception.

If newrelic.linkingmetadata property is present in an event, it will be unrolled into individual NewRelic properties used for "logs in context".

Install via NuGet

PM> Install-Package Serilog.Sinks.NewRelic.Logs

JSON configuration

It is possible to configure the sink using Serilog.Settings.Configuration by specifying the license key and other desired parameters in appsettings.json:

{
  "Serilog": {
    "Using": [ "Serilog.Sinks.NewRelic.Logs" ],
    "WriteTo": [
      {
        "Name": "NewRelicLogs",
        "Args": {
          "applicationName": "NewRelicLogTestSample",
          "licenseKey": "58e9892abd3f09d91b0db0d0e9e95628FFFFNRAL"
          //... other parameters
        }
      }
    ],
    "Enrich": [ "FromLogContext", "WithMachineName", "WithThreadId", "WithNewRelicLogsInContext" ]
  }
}
