[mrtg] Re: DOS popup boxes with external Perl Script

One suggestion to stop these new windows popping up, is that you can use the
Win32::Process perl module to start sub-processes. The CREATE_NO_WINDOW
switch will suppress these new windows. (See script below for example ...)

Cheers

Subject: [mrtg] DOS popup boxes with external Perl Script


I have configured the MRTG cfg file to use an external Perl script to gather
data as follows.
 

Target[db1-memory-availableBytes]:`perl c:\TheSpecializt\getlog2.pl
Z:\DB1.CSV "\\DB1\Memory\Available Bytes"`

 

This works perfectly but what happens is it spawns a cmd session and a perl
session for each device. So you could imagine when monitoring 15 devices
each having 6 items being probed the number of DOS popup boxes that appears
becomes quite annoying.

 

MRTG is setup to run as a daemon and is started as follows.

 

start /MIN /B /Dc:\mrtg-2.9.29\bin wperl mrtg --logging=eventlog
C:\TheSpecializt\Client_Services\Utilisation_Graphs\TheSpecializt\Cfg\mrtg.c
fg

 

As you can see I tried using the START command with the /MIN and /B switches
no luck. I also tried sticking the START command and switches in the cfg
file but also no luck.

 

Any ideas?

 

Regards,
