*** Poller returning a zero value for perl scripts ***

[celtic6969]

I have a strange problem where if I run a perl script manually (as cactiuser) then it returns non-zero values, but when the poller runs automatically it returns zeros
I have checked permissions, recreated data sources, run through the "troubleshooting NAN values document" and not sure what else to try ...

[root@cactiserver root]# su - cactiuser
[cactiuser@cactiserver cactiuser]$ /usr/bin/php /usr/local/cacti/poller.php
08/10/2007 09:29:08 AM - POLLER: Poller[0] Parsed MULTI output field 'active:3' [map active->active]
08/10/2007 09:29:08 AM - POLLER: Poller[0] Parsed MULTI output field 'idle:7' [map idle->idle]
08/10/2007 09:29:08 AM - POLLER: Poller[0] Parsed MULTI output field 'total:10' [map total->total]
08/10/2007 09:29:08 AM - POLLER: Poller[0] CACTI2RRD: /usr/local/bin/rrdtool update /usr/local/cacti/rra/isdn_router_active_124.rrd --template active:idle:total 1186702146:3:7:10

Any help would be really appreciated
Thanks

Hi Reinhard, thanks for the reply and apologies for cross posting. I'm not sure how to delete the other posts.
Although I get the desired result when running the script from the command line, the script wont work with the poller. I don't have much knowledge of scripting or how it integrates with the poller. Perhaps you can suggest another way of doing it ?

Much Appreciated

#!/usr/bin/perl

$in_hostname = $ARGV[0] if defined $ARGV[0];
$in_version = $ARGV[1] if defined $ARGV[1];
$in_community = $ARGV[2] if defined $ARGV[2];

$in_oid = ".1.3.6.1.2.1.10.20.1.2.1.1.2";

if ($in_version eq "2")

$in_version = "2c";

}
print "active:$_active idle:$_idle total:$_total";

Which poller are you running, cmd.php or cactid? If cactid, which version (./cactid -- version)

Hi Reinhard,

I am currently using cmd, although I'm pretty sure I had the same issue when I tried cactid. Do you want me to try cactid again ?

Hi Reinhard,

I have tried testing with cactid and also another script, but I still gett the same results. Here is my cactid version info:

[root@cacti reporter]# ./cactid --version
CACTID 0.8.6i Copyright 2002-2006 by The Cacti Group

Usage: cactid [options] [firstid lastid]

To be honest, I'm stumped. Are you able to write the contents of the @output array to some arbitrary file while running under cactid/cmd.php?

I had a similar issue and it turned out to be that user that my poller was running under did not have rights to the file in question. But when I ran from the command line of course I did have rights. Not sure if that helps or not.
