Metron

Metron is simple metrics library.

Get started

1. Create model which inherits from Model. Model contains Guid Id and DateTimeOffset CreatedAt properties which initialized at parameterless constructor.

public sealed class UserLoggedIn : Model 
{
  public string Username { get; set; }
}

2. Initialize repository which implements IModelRepository

public sealed class InMemoryRepository : IModelRepository<UserLoggedIn> 
{
  private readonly List<UserLoggedIn> _items;
  
  public InMemoryRepository()
  {
    _items = new List<UserLoggedIn>();
  }
  
  public Task Add(UserLoggedIn model, CancellationToken cancellationToken = default)
  {
    _items.Add(model);
    return Task.CompletedTask;
  }
    
  public Task<IReadOnlyCollection<UserLoggedIn>> Get(CancellationToken cancellationToken = default)
    => Task.FromResult<IReadOnlyCollection<UserLoggedIn>>(_items);
}

3. Initialize Metron instance with created repository.

var repository = new InMemoryRepository();
var metron = new Metron(repository);

4. Use metron instance to write and get metrics.

var item = new UserLoggedIn { Username = "root" };
await metron.Add(item);
var items = metron.Get(CancellationToken.None);
