Custom Filters

Implement ILogFilter:

using Logix.Abstractions;

public class KeywordFilter : ILogFilter
{
    private readonly string[] _keywords;

    public KeywordFilter(params string[] keywords) => _keywords = keywords;

    public bool ShouldLog(LogMessage msg)
    {
        if (msg.Message == null) return true;
        foreach (var kw in _keywords)
            if (msg.Message.ToString().Contains(kw, StringComparison.OrdinalIgnoreCase))
                return true;
        return false;
    }
}

ShouldLog receives the full LogMessage with Created, Level, Message, File, Line, and StackTrace.

Log.Container.AddFilter(new KeywordFilter("urgent", "critical"));
