It works fine for me in 2.0.5

Does ExternalScripts variable in zabbix config points to where the script is?

My template's item are like:
ipmi_sensors.pl['FAN 1', numeric, {$IPMI_HOSTNAME}]

So, it's much like yours.
Try to run this script as a zabbix user, maybe there's some permission issue.
Does zabbix user have rights to write to a directory where the cache files are?
In my case it's /var/tmp, but maybe you've changed it.

Hi Blind_Oracle
Definitely works if I su zabbix or su - zabbix, which is my zabbix usr account, and run ipmi_sensors.pl, I did change the temp directory, but the file is being written to:
*********************************
Output from running as zabbix user:

zabbix@zabbixsvr:/usr/local/share/zabbix/externalscripts> ./ipmi_sensors.pl 'Fan1 RPM' numeric 192.168.128.175
2760.00
*********************************
But the zabbix shows log shows [] as the output.

Many thanks for your help
Mike

So, the cache file is being created? Does it contain the right data?

It is permissions

Hi,
It is permissions. I had the permissions set as user root grp zabbix rwr-xr-x ipmi-sensrs.pl and on temp dir when working.
If I change the owner to zabbix on both script and tmp dir and output file I get no return. not sure what permissions to use?
Thanks, I am in tghe right area now.
Regards
Mike

I have the script as zabbix:zabbix and 0550 chmod.

The temp dir is usual /var/tmp which is root:root and 41777 (sticky bit)

Hi,
Still getting "became not supported: Received value [] is not suitable for value type [Numeric (unsigned)] and data type [Decimal]"

In the zabbix server log, setup the same as you suggested in the last post and get correct response if I run the query as zabbix user from the command line.
Regards
Mike

Sorry, i have no more ideas.
The fact that script works from shell indicates that there's some problem with your OS or zabbix setup.

Here's the latest version of the script (don't remember if it's any different from the one i've already posted), just in case:

Code:

# cat ipmi_sensors.pl
#!/usr/bin/perl -w

use strict;
use warnings;
use Fcntl ':flock';

my $sensor = $ARGV[0];
my $type = $ARGV[1];
my $server = $ARGV[2];

$type = 'numeric' if not defined $type;
exit(1) if not defined $server or not defined $sensor;

$sensor =~ s/\'//g;

my $expires = 60;

my $user = 'zabbix';
my $pass = 'xxxxxxxx';

my $ipmi_cmd = '';
my $cache_file = '/var/tmp/ipmi_sensors_'.$server;
$ipmi_cmd = '/opt/freeipmi/sbin/ipmi-sensors -D LAN2_0 -h '.$server.' -u '.$user.' -p '.$pass.' -l USER -W discretereading --no-header-output --comma-separated-output 2>/dev/null';

my @rows = ();
if(not -e $cache_file) {
    open(CACHE, '>>', $cache_file);
    if(flock(CACHE, LOCK_EX | LOCK_NB)) {
        my $results = results();
        if(defined $results) {
            truncate(CACHE, 0);
            print CACHE $results;
            close(CACHE);
        } else {
            close(CACHE);
            unlink($cache_file);
            exit(1);
        }
    }
} else {
    open(CACHE, '>>', $cache_file);
    if(flock(CACHE, LOCK_EX | LOCK_NB)) {
        my @stat = stat($cache_file);
        my $delta = time() - $stat[9];
        if($delta > $expires or $delta < 0) {
            my $results = results();
            if(defined $results) {
                truncate(CACHE, 0);
                print CACHE $results;
                close(CACHE);
            } else {
                close(CACHE);
                unlink($cache_file);
                exit(1);
            }
        }
    }
}

open(CACHE, '<' . $cache_file);
flock(CACHE, LOCK_EX);
@rows = <CACHE>;
close(CACHE);

foreach my $row (@rows) {
    my @cols = split(',', $row);
    
    if($cols[1] eq $sensor) {
        if($type eq 'discrete') {
            my $r = $cols[5];
            $r =~ s/\'//g;
            chop($r);
            print $r;
        } elsif($type eq 'numeric') {
            if($cols[3] eq '' or $cols[3] eq 'N/A') {
                print "0";
            } else {
                print $cols[3];
            }
        }
    }
}

sub results {
    my $results = `$ipmi_cmd`;
    if($? == 0) {
        return $results;
    } else {
        return undef;
    }
}

You are a star!

That is it. I can see what is was now, but it wasn't obvious - I had tried outputting to a text file and I couldn't see it then - there was an extra control character. New script works a treat. Thanks for all your help.

Yes, i see that there was a newline in the end.
Looks like that i've dealt with the same issue and removed it, but have forgotten about it

Maybe someone can help? Created script in zabbix external scripts directory and added chmod +x rights. When I run this script no output is provided.

Code:

 ./ipmi_sensors.pl 'Temp 1' numeric x.x.x.x

When runing from command line like this I can get data

Code:

 ipmi-sensors -D LAN2_0 -h hostname -u user -p pass  -l USER -W discretereading
