Using ElmahCore

ELMAH for Net.Standard and Net.Core

Add nuget package elmahcore

Simple usage

Startup.cs

1)	services.AddElmah() in ConfigureServices 
2)	app.UseElmah(); in Configure

app.UseElmah() must be after initializing other exception handling middleware, such as (UseExceptionHandler, UseDeveloperExceptionPage, etc.)

Default elmah path ~/elmah.

Change URL path

services.AddElmah(options => options.Path = "you_path_here")

Restrict access to the Elmah url

services.AddElmah(options =>
{
        options.CheckPermissionAction = context => context.User.Identity.IsAuthenticated;
});

Note: app.UseElmah(); needs to be after

app.UseAuthentication();
app.UseAuthorization();
app.UseElmah();

or the user will be redirected to the sign in screen even if he is authenticated.

Change Error Log type

You can create your own error log, which will store errors anywhere.

    class MyErrorLog: ErrorLog
    //implement ErrorLog

This ErrorLogs available in board:

  • MemoryErrorLog – store errors in memory (by default)
  • XmlFileErrorLog – store errors in XML files
  • SqlErrorLog - store errors in MS SQL (add reference to ElmahCore.Sql)
services.AddElmah<XmlFileErrorLog>(options =>
{
    options.LogPath = "~/log"; // OR options.LogPath = "с:\errors";
});
services.AddElmah<SqlErrorLog>(options =>
{
    options.ConnectionString = "connection_string"; // DB structure see here: https://bitbucket.org/project-elmah/main/downloads/ELMAH-1.2-db-SQLServer.sql
});

Rise exception

public IActionResult Test()
{
    HttpContext.RiseError(new InvalidOperationException("Test"));
    ...
}

Using Notifiers

You can create your own notifiers by implement IErrorNotifier interface and add notifier to Elmah options:

services.AddElmah<XmlFileErrorLog>(options =>
{
    options.Path = @"errors";
    options.LogPath = "~/logs";
    options.Notifiers.Add(new ErrorMailNotifier("Email",emailOptions));
});

Each notifier must have unique name.

Using Filters

You can use Elmah XML filter configuration in separate file, create and add custom filters:

services.AddElmah<XmlFileErrorLog>(options =>
{
    options.FiltersConfig = "elmah.xml";
    options.Filters.Add(new MyFilter());
})

Custom filter must implement IErrorFilter. XML filter config example:

<?xml version="1.0" encoding="utf-8" ?>
<elmah>
	<errorFilter>
		<notifiers>
			<notifier name="Email"/>
		</notifiers>
		<test>
			<and>
				<greater binding="HttpStatusCode" value="399" type="Int32" />
				<lesser  binding="HttpStatusCode" value="500" type="Int32" />
			</and> 
		</test>
	</errorFilter>
</elmah>

JavaScript filters not yet impemented 😦

Add notifiers to errorFilter node if you do not want to send notifications Filtered errors will be logged, but will not be sent.
