Log4Net Levels Numeric Values

Question

I can't seem to find the numeric values for the predefined levels in Log4Net. Can anybody point me to them?

Answer 1

The trunk code for Level.cs gives these numbers:

• Emergency: 120000
• Fatal: 110000
• Alert: 100000
• Critical: 90000
• Severe: 80000
• Error: 70000
• Warn: 60000
• Notice: 50000
• Info: 40000
• Debug: 30000
• Fine: 30000
• Trace: 20000
• Finer: 20000
• Verbose: 10000
• Finest: 10000

Here is an excerpt from the Level class (decompiled with .net reflector)

  public static readonly Level Alert = new Level(0x186a0, "ALERT");
    public static readonly Level All = new Level(-2147483648, "ALL");
    public static readonly Level Critical = new Level(0x15f90, "CRITICAL");
    public static readonly Level Debug = new Level(0x7530, "DEBUG");
    public static readonly Level Emergency = new Level(0x1d4c0, "EMERGENCY");
    public static readonly Level Error = new Level(0x11170, "ERROR");
    public static readonly Level Fatal = new Level(0x1adb0, "FATAL");
    public static readonly Level Fine = new Level(0x7530, "FINE");
    public static readonly Level Finer = new Level(0x4e20, "FINER");
    public static readonly Level Finest = new Level(0x2710, "FINEST");
    public static readonly Level Info = new Level(0x9c40, "INFO");
    private readonly string m_levelDisplayName;
    private readonly string m_levelName;
    private readonly int m_levelValue;
    public static readonly Level Notice = new Level(0xc350, "NOTICE");
    public static readonly Level Off = new Level(0x7fffffff, "OFF");
    public static readonly Level Severe = new Level(0x13880, "SEVERE");
    public static readonly Level Trace = new Level(0x4e20, "TRACE");
    public static readonly Level Verbose = new Level(0x2710, "VERBOSE");
    public static readonly Level Warn = new Level(0xea60, "WARN");

Can someone please explain what is the "best practice" of using those error levels? What is the relationship between them?

Thank you, Ido.
