Description

EventLogReader.cs lines 63–76 map Windows Event Log levels to EventLogLevel but omit level 1 (Critical). Critical events fall through to the default case and are classified as Information.

Code

public static EventLogLevel ParseLevel(byte level)
{
    switch (level)
    {
        case 2: return EventLogLevel.Error;
        case 3: return EventLogLevel.Warning;
        case 4: return EventLogLevel.Information;
        default: return EventLogLevel.Information;  // level 1 (Critical) lands here
    }
}

Windows Event Log Standard Levels

Impact

Critical system events (e.g., service crashes, unrecoverable failures) appear as "Information" in the Servy Manager UI, hiding their true severity from operators.

Suggested Fix

case 1: return EventLogLevel.Error;  // Critical → map to Error (closest match)
case 2: return EventLogLevel.Error;

Or add a Critical value to the EventLogLevel enum for full fidelity.
