If you wish to follow the development of the new Munin Node for Windows, go to this repository

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. This is different from the standard munin-node client, which only uses external plugins written as shell and Perl scripts.

The installer may be run with different command-line flags.

• /HELP or /? Shows the help message.
• /SILENT or /VERYSILENT Instructs the installer to be silent or very silent.
• more options are available. The full list is displayed in /HELP or on the Inno Setup website.

The munin-node executable takes these command-line flags.

• -install Install as a system service.
• -uninstall Removes the installed service.
• -quiet Close the console window, running in the background.
• -run Run as a normal program, rather than a service.

The configuration file munin-node.ini uses the standard INI file format.

The main section is the Plugins section which defines which plugins are enabled and which are disabled. Use 1 to enable and 0 to disable. Most plugins handle failing to load gracefully, however some may have a bug (if so please report :).

You can disable plugins you don't want, to save on memory and cpu usage.

• CPU (cpu):
  • Reports the current user cpu usage
• Disk (df):
  • Reports disk drive space usage
  • Configuration in DiskPlugin section.
• HD (hdd):
  • Reports HardDrive temperature
• Spin (spinup)
  • Reports HardDrive spin-up time
• Online (onlinehours)
  • Reports the total HardDrive Online Hours
• Readerror (readerrorrate)
  • Reports the HardDrive Read Error Rate
• Startstop (startstopcyclehdd)
  • Reports the total HardDrive Start Stop Cycles
• Reallocsector (reallocsectorcount)
  • Reports the HardDrive reallocated sector count
• Seekerror (seekerrorrate)
  • Reports the HardDrive Seek-Error rate
• Spinretry (spinretrycount)
  • Reports the HardDrive Spin Retry count
• Reporteduncorr (reporteduncorrectableerrors)
  • Reports the HardDrive Reported Uncorrectable errors
• Poweroffretract (poweroffretract)
  • Reports the amount of Unsafe Shutdowns in the HardDrive's lifetime
• Memory (memory):
  • Reports memory usage
• Process (processes):
  • Reports process and thread count
• Network (network):
  • Reports network bytes send and received
• MBM (mbm, mbm_volt, mbm_fan, mbm_cpu):
  • Reports sensor data from Motherboard Monitor
• SpeedFan (speedfan):
  • Reports sensor data from SpeedFan xAP broadcasts
  • Configuration in SpeedFanPlugin section. You have to change the BroadcastIP and UID settings to match SpeedFan (Configuration->xAP)
• Performance Counter:
  • Reports performance counter values, very extenable to monitor any counter
  • An instance of this plugin is created for every section starting with PerfCounterPlugin in the Configuration. For example there is a PerfCounterPlugin_uptime section in the stock configuration file. This defines a plugin with a name of uptime.

  • An example section is listed below :

    ; The Object and Counter settings are used to access the Performance Counter
    ; For uptime this would result in \System\System Up Time
    Object=System
    Counter=System Up Time
    ; The Graph settings are reported to munin
    GraphTitle=Uptime
    GraphCategory=system
    GraphDraw=AREA
    GraphArgs=--base 1000 -l 0
    ; The DropTotal setting will drop the last instance from the counter list, 
    ; which is often _Total
    ; Has no effect on single instance counters (Uptime)
    DropTotal=0
    ; The CounterFormat setting controls what format the counter value is read in as 
    ; a double, int, or large (int64).
    ; The plugin always outputs doubles, so this shouldn't have that much effect
    CounterFormat=large
    ; The CounterMultiply setting sets a value the counter value is multiplied by, 
    ; use it to adjust the scale
    ; 1.1574074074074073e-005 is the result of(1 / 86400.0), 
    ; the uptime counter reports seconds and we want to report days.
    ; So we want to divide the counter value by the number of seconds in a day, 86400.
    CounterMultiply=1.1574074074074073e-005

• External Plugin:
  • A plugin that supports external plugins in the style of munin-node.
  • Configuration in [ExternalPlugin] section. Just add an entry with the path to the program to run, It doesn't matter what the name of the name=value pair is.
  • The output of the external program should be similar to the following,

  • Note: add quotes (") around the value if it has spaces! :

    >disk_free.py name
    drive_free
    
    >disk_free.py
    drive_free_c.value 40.3635149113
    .
    
    >disk_free.py config
    graph_title Filesystem free (in %)
    graph_category disk
    graph_info This graph shows the amount of free space on each disk.
    graph_args --upper-limit 100 -l 0
    graph_vlabel %
    drive_free_c.label C:
    .
