serilog-sinks-signalr-core
A Serilog' sink that writes event to SignalR Hub.
Inspired by serilog-sink-signalr, I decided to rewrite it because this latter is not fully compatible with Microsoft.AspNetCore.SignalR.Core.
Usage and configuration
The hub to use with the Sink must be strong-typed and must extend the interface ISerilogHub. An example is as follows
public SerilogHub : Serilog.Sinks.SignalR.Core.Interfaces.ISerilogHub
{}An example sink' setup is as follows
[...]
var hub = ServiceProvider.GetService<IHubContext<SerilogHub, ISerilogHub>>();
Log.Logger = new LoggerConfiguration()
.WriteTo.SignalR(
hub,
formatProvider: new CustomFormatProvider(),
groups: new [] { "group1", },
userIds: new [] { "user2", },
excludedConnectionIds: new [] { "1", }
)
.CreateLogger();
[...]
app.UseSignalR(conf => {
conf.MapHub<SerilogHub>("/log");
})Receive the log events
In the client code, subscribe to the PushEventLog method.
[...]
var connection = new HubConnectionBuilder()
.WithUrl("http://localhost:8080/log")
.Build()
connection.On<string>("PushEventLog", (string message) => {
Console.WriteLine(message);
});
[...]Options
In the package it's also available an abstract base hub (BaseSerilogHub), that can be extended and that gives some utility functions (like SubscribeToGroup). Hence, feel free to extend that class if you want.
