Wondering if you would be willing to add server fps.

search "private string Format(string message)" and add this lines:

.Replace("{server.fps}", Performance.current.frameRate.ToString())
.Replace("{server.avgfps}", Convert.ToInt32(Performance.current.frameRateAverage).ToString())

use placeholders {server.fps} (fps at this moment) or {server.avgfps} (average fps)

Thank you!
