Windows WMI with Cacti on Linux server

[laffen]

Hi,

has anyone graphed Windows 2000/2003 servers using WMI when Cacti is installed on a *nix (Linux/FreeBSD/whatever) server? All the examples I have seen so far has been for Cacti running on Windows using PHP/Visual Basic scripts which is no good on my Debian Linux.

I suck at coding so don't want to start putting it together myself unless as a last resort, so any scripts or help would be appreciated

I am also looking for this!

Hi

I think you can use the scripts writed for win2k. They are written in perl, so normally, it works perfeclty under linux. But you must be sure to have this library: Win32::OLE

Cause the scripts use this library the interact with the wmi.

Can somone confirm that ?

This could be a solution, but there is no Win32::OLE perl module for Debian, and it borked when I tried to install it via CPAN.
I would prefer perl modules installed via packages (apt) instead of CPAN installed modules to keep the system consistent.

So.. why don't you try with php ?

but, it's not an "easy way"...

Can't be done. Win32::OLE can be built *only* on Win32 machines.

Cheers,

So it appears that you cannot compile Win32::OLE.

I guess I will have to investigate the PHP option mentioned in the post above.

Cool, please keep us posted about how its going

In order to monitor Windows servers from a linux box with WMI,

you should use NRPE_NT.

Perl scripts posted in this forum can be easily adapted :

Per exemple, on cacti :
Original "input string" was :
perl <path_cacti>/scripts/w32_query_LogicalDisk.pl <hostname> <driveletter>
New "input string" :
<path_cacti>/scripts/check_nrpe -H <nrpe_hostname> -c check_disk -a <hostname> <driveletter>

where <nrpe_hostname> is the windows server where nrpe_nt is installed.

In "nrpe_nt.cfg" file, add a line like this :
command[check_disk]=c:\perl\bin\perl.exe C:\nrpe\bin\w32_query_LogicalDisk.pl $ARG1$ get size,freespace $ARG2$

excellent NC

great tip, works perfect

thx again

Is there any way around this if you don't have access to the Windows servers to install nrpe_nt??

[NC]

You can install nrep_nt on any windows OS (2000 workstation/server , XP, 2003).
So, in order to test, I've installed nrpe_nt on my computer (XP).
The service is launched with an account which have some administrator's rights on domain.

So it doesn't need to be installed on every server???

Hi,

At the company where I work we use the windows Nagios agent on the NT/2000/2003 boxes that we monitor.

see this post for more info http://forums.cacti.net/viewtopic.php?t=1041

The nagios agent has the advantage that you only need to create the script on you Cacti/*nix box. On your Windoze box you only have to make sure that the agent service runs and it is stable.

The second page of the post contains an active example of a graph using the nagios agent.

The agent can be downloaded from http://nsclient.ready2run.nl/download.htm
You need to install it on every server that you want to monitor.

You can olso install cacti on a Linux machine, NRPE_NT on 1 NT/W2K/W2K3/XP host and create template which interorage others hosts via
WMI

example:

check_wmi.pl on linux host
#!/usr/bin/perl

$response=`/var/www/cacti/scripts/check_nrpe -t 1000 -H hostnameofthenrpe_nthost -c $ARGV[0] -a $ARGV[1] $ARGV[2] $ARGV[3] $ARGV[4]`;
chomp $response;
print "$response\n";

example of commands in nrpe.cfg :
#check disk $ARG1$=hostname $ARG2$=letter
command[check_disk]=cscript //nologo //T:1000 C:\nrpe\bin\scripts\check_wmi_disk.vbs $ARG1$ $ARG2$
#check mem $ARG1$=hostname
command[check_mem]=cscript //nologo //T:1000 C:\nrpe\bin\scripts\check_wmi_mem.vbs $ARG1$
#check mem $ARG1$=hostname
command[check_cpu]=cscript //nologo //T:1000 C:\nrpe\bin\scripts\check_wmi_cpu.vbs $ARG1$
