I've posted v1.5 of Munin Node for Windows.
Summary Munin Node for Windows AKA munin-node-win32, is a Windows client for the Munin monitoring system.
It is written in C++ with most plugins built into the executable. Which is different from the standard munin-node client, which only uses external plugins written as shell and Perl scripts.
Change Log for v1.5 + Added readme documentation + Updated -install / -uninstall switches to handle Window Firewall exceptions + Added SpeedFan plugin + Added External Plugins plugin, external plugins are now supported + Added Generic Performance Counter plugin + Removed Uptime, Disktime plugins. Replaced with the Generic Performance Counter plugin + Improved error handling in Cpu plugin + Now Unicode compatible + Fixed memory leaks + Improved multi-thread safety + Added better Event Log support
