External check item

[mike13]

Hi,

I'm currently having an issue with External check item. I've written a perl script to ping my hosts in mpls vrf.
When i call it from zabbix as an External check type i have the following error messages:
sh: /etc/zabbix/externalscripts/sw_ping.pl: Permission denied
Item [test:sw_ping.pl[172.17.148.182,xyz,password,VRF-182-TEST1, 192.168.15.16]]error: Script /etc/zabbix/externalscripts/sw_ping.pl returned nothing.

Although the script has correct permission(-rwxrwxrwx 1 root zabbix 1267 May 5 06:57 sw_ping.pl) i can't figure out this problem.

Here are the parameters of my item:

Host:test
Description: switch ping
Type: External check
Key:sw_ping.pl[172.17.148.182,xyz,password,VRF-182-TEST1, 192.168.15.16]


My script do the following:
1) login to a router via telnet
2) do a ping vrf
3) return 1(when ping successes) or 0 (unsuccessful)

Here is my script:
#!/usr/bin/perl
if ($#ARGV != 4) {
print "usage: ip useer pwd vf host";
exit;
}
use strict;
use warnings;
use Net::Telnet::Cisco;
my $ip= $ARGV[0];
my $user= $ARGV[1];
my $pwd= $ARGV[2];
my $vf= $ARGV[3];
my $host= $ARGV[4];
my $result =0;
my $session = Net::Telnet::Cisco->new(Host => $ip);
$session->login($user, $pwd);
# Execute the ping command
my @output = $session->cmd("ping vrf $vf $host");
# print @output;
my $info ="";
foreach $info (@output) {
chomp($info);
#print $info;
if ($info =~ /Success rate is 100/) {
$result=1; #print "-ok";
}
else{
$result=0; #print"-nok";
}
#print "\n";
}
#print "\n";
print $result;
$session->close;

How to resolve it?
Any suggestions would be appreciated.

Many Thanks

did you find a solution ?
zabbix user must have execute permissions on the script.
Did you try :
su zabbix
/etc/zabbix/externalscripts/sw_ping.pl

?

The script has 777 rights. But the error message still remains.

Thanks,

Hello mike13. Although your script has 777 rights, Simon might be right. Maybe zabbix agent doesn't have permissions on /etc/zabbix/externalscripts/ directory. Try this:

chown zabbix.zabbix -R /etc/zabbix/
