Nagiosgraph from NSClient++ (Windows) Checks

To create automatic graphics from Nagios, Nagiosgraph is a very handy and powerful tool. In the so-called 'map' configurations file there are already a lot of examples for Unix/Linux checks but none for NSClient++/Windows checks.

On the following websites I found examples but unfortunately they didn't seem to work:

So I worked a bit on them and got the following ones to work:

CPU Load (Nagios output: CPU Load 23% (15 min average) )
This one is based on the example delivered on

/output:.*CPU Load .*?(\d+)%/
and push @s, [ ntload,
        ['avg15min', GAUGE, $1 ] ];

Memory Usage (Nagios output: Memory usage: total:9732.64 Mb - used: 2189.29 Mb (22%) - free: 7543.35 Mb (78%) )
This map-entry works with the actual NSClient++ (0.3.6-0.3.8) outputs and has been written by Fabien Huttin:

# Service type memory for Windows (NSClient++)
# Regex by Fabien Huttin
#output: Memory usage: total:9732.64 Mb - used: 2203.30 Mb (23%) - free: 7529.34 Mb (77%)
/output:Memory usage.*:.*:(\d+)\.\d* Mb .*: (\d+)\.\d* Mb .*: (\d+)\.\d* Mb .*/
and push @s, [ntmem,
       ['memtotal', GAUGE, $1*1024**2 ],
        ['memused', GAUGE, $2*1024**2] ];

Disk/Partition utilization  (Nagios output: c: - total: 40.00 Gb - used: 22.69 Gb (57%) - free 17.31 Gb (43%) )
This map-entry works with current NSClient++ versions (0.3.6-0.3.8) and was written by me:

# Service tpye disk space for Windows (NSClient++)
# by Claudio Kuenzler
# Nagios Output: c: - total: 40.00 Gb - used: 22.69 Gb (57%) - free 17.31 Gb (43%)
/output:.* total: (\d+\.\d*) Gb .*used: (\d+\.\d*) Gb .*free (\d+\.\d*).*/
and push @s, [ntdisk,
       ['disktotal', GAUGE, $1*1000**3 ],
        ['diskused', GAUGE, $2*1000**3 ] ];

Hi Erwin, here is an example how to monitor the CPU with NSclient on the Windows server:

# Check CPU Usage
define service{
use generic-service
host_name mywindowshost
service_description CPU Usage
check_command check_nt!CPULOAD!-l 5,85,95

good day all,

cant you shown up the config for monitor services of windows machines (e.g. Computer Browser, Workstation, etc.)

God Bless!!
