yes, although I'm no real perl-guru, just replace
$emailuser = "root";
with
$emailuser = "user\@domain.com";

Note the backslash in front of the special @-char..

Hi Michael

Thanks for all your help

One last question. Is there a way to specify an external mail address in the
script? Should I change the $emailuser to a full email address. 

Thanks for all your patience

Regards
Brendon

Hi,

yes, these are global options which saves each of them to be added per host.

You only have to add each threshold per target where you want thresholds to
be active then, 
an examle for monitoring CPU and mem on a Cisco router looks somethink like
this:
########################### Router-specific
Target[HOSTNAME.cpu]:
1.3.6.1.4.1.9.2.1.57.0&1.3.6.1.4.1.9.2.1.58.0:COMMUNITY at HOSTNAME
Directory[HOSTNAME.cpu]: HOSTNAME
MaxBytes[HOSTNAME.cpu]: 100
Title[HOSTNAME.cpu]: CPU Usage -- HOSTNAME
PageTop[HOSTNAME.cpu]: <H1>CPU Usage -- HOSTNAME</H1>
Options[HOSTNAME.cpu]: gauge, absolute
Unscaled[HOSTNAME.cpu]: dwmy
#Supress[HOSTNAME.cpu]:dwmy
XSize[HOSTNAME.cpu]: 380
YSize[HOSTNAME.cpu]: 100
YLegend[HOSTNAME.cpu]: CPU Usage (%)

Legend1[HOSTNAME.cpu]: CPU Usage 1 min&nbsp;
Legend2[HOSTNAME.cpu]: CPU Usage 5 min&nbsp;
LegendI[HOSTNAME.cpu]: CPU Usage 1 min&nbsp;
LegendO[HOSTNAME.cpu]: CPU Usage 5 min&nbsp;
ThreshMaxO[HOSTNAME.cpu]: 90
#---------------------------------------------------------------
Target[HOSTNAME_freemem]:
1.3.6.1.4.1.9.9.48.1.1.1.6.1&1.3.6.1.4.1.9.9.48.1.1.1.6.2:COMMUNITY at HOSTNAME
Directory[HOSTNAME_freemem]: HOSTNAME
MaxBytes[HOSTNAME_freemem]: 64000000
AbsMax[HOSTNAME_freemem]: 64000000
Title[HOSTNAME_freemem]: Free Memory -- HOSTNAME
PageTop[HOSTNAME_freemem]: <H1>Free Memory -- HOSTNAME</H1>
Options[HOSTNAME_freemem]: gauge, nopercent
#Unscaled[HOSTNAME_freemem]: dwmy
YLegend[HOSTNAME_freemem]: Free Memory
ShortLegend[HOSTNAME_freemem]: B
LegendI[HOSTNAME_freemem]: &nbsp;Proc mem:
LegendO[HOSTNAME_freemem]: &nbsp;I/O mem:
Legend1[HOSTNAME_freemem]: Processor memory:
Legend2[HOSTNAME_freemem]: I/O memory:
ThreshMinI[HOSTNAME_freemem]: 1000000
ThreshMinO[HOSTNAME_freemem]: 1000000
#---------------------------------------------------------------

All options are described here

cking

By the way, I think it would be better to send answers to the list..

Hi Michael

Excuse my ignorance
Are all these options below global options? Or must you add the: 
ThreshProgI[_]: /usr/local/mrtg/bin/mrtg_thresh_alert.pl
ThreshProgO[_]: /usr/local/mrtg/bin/mrtg_thresh_alert.pl
ThreshProgOKI[_]: /usr/local/mrtg/bin/mrtg_thresh_alert.pl
ThreshProgOKO[_]:
/usr/local/mrtg/bin/mrtg_thresh_alert.pl......................per host?
Also........is it possible to add a few external addresses (in another
domain) for it to send to? How you would achieve this?

Thanks for all your help

Regards
Brendon

Hi,

I picked up the attached perl-script somewhere, it worked for me on RH7.1 ..

configured globally in mrtg.cfg looks like this: 

ThreshDir: /var/spool/mrtg
ThreshProgI[_]: /usr/local/mrtg/bin/mrtg_thresh_alert.pl
ThreshProgO[_]: /usr/local/mrtg/bin/mrtg_thresh_alert.pl
ThreshProgOKI[_]: /usr/local/mrtg/bin/mrtg_thresh_alert.pl
ThreshProgOKO[_]: /usr/local/mrtg/bin/mrtg_thresh_alert.pl

Hi everyone

Please could someone help me out with a script for linux that will email a
few users when a threshold in mrtg is reached.
I am not much of a programmer at all

Thanks

Regards
Brendon
