Tags
Tags allow you to categorize errors.
To attach tags to an incident you can do the following:
try
{
    //some stuff that generates an exception
}
catch (Exception ex)
{
    Err.Report(ex, new { ErrTags = "important,backend" });
    // alternative:
    // Err.Report(ex, new { ErrTags = new[] { "important", "backend" }});
}

Add a tag to every report
To add an tag to every report (like a server name), you can use a custom context provider.
public class ServerNameProvider : IContextInfoProvider
{
    public string Name => "ServerName";
    public ContextCollectionDTO Collect(IErrorReporterContext context)
    {
        var properties = new Dictionary<string, string>();
        properties.Add("ErrTags", Environment.MachineName);
        return new ContextCollectionDTO(Name, properties);
    }
}
The .NET Standard version of the interface is named IContextCollectionProvider instead of IContextInfoProvider.
To activate the provider, register it using Err.Configuration:
Err.Configuration.ContextProviders.Add(new ServerNameProvider());

Finding incidents using tags
Once you have added tags you can use them to find specific incidents in the search interface:
