Application logging

This section provides information on how to log information in your worker applications.

Logging in worker commands​

In your worker application, the default logging infrastructure is already set up. Use the Logger property of the command to quickly log messages using the ILogger API.

using System.Net;
using Taskurai.Models;
using Taskurai.Worker;

public class TestControllerSerializable: WorkerController
{
  private readonly IConfiguration _configuration;


  public TestControllerSerializable(IConfiguration configuration)
  {
    _configuration = configuration;
  }

  [Command]
  public async Task<string> GetIPLocation(
    TaskuraiTaskContext context, 
    CancellationToken cancellationToken, 
    string ipv4)
  {
    Logger.LogInformation("Looking up IP location for {IpAddress}", ipv4);

    if (string.IsNullOrEmpty(ipv4))
    {
      Logger.LogError("Invalid IP address provided: {IpAddress}", ipv4);
      throw new ArgumentException("Invalid IP address");
    }

    // Simulate work
    await Task.Delay(5000, cancellationToken);

    var location = "Amsterdam, Netherlands";

    Logger.LogInformation("IP lookup result for {IpAddress}: {Location}", ipv4, location);

    // Simulate lookup
    return location;
  }
}

Logging configuration​

The Worker SDK uses the Serilog library to offer structured logging.

Logging can be configured in the appsettings.json for each worker that is deployed to Taskurai.

appsettings.json
{
  "Serilog": {
    "MinimumLevel": {
      "Default": "Information",
      "Override": {
        "Microsoft": "Warning",
        "System": "Warning",
        "Taskurai": "Information",
        "Taskurai.Worker": "Information"
      }
    }
  },
  ...
}
