Nagios – Twitter alerts

/ Daemon, Scripting /

This entry will cover how to send nagios alerts to twitter, in the examples to follow using curl.

Firstly edit commands.cfg

And add the two following line:

define command {
command_name notify-by-twitter
command_line /usr/bin/curl --basic --user "twitteruser:twitterpassword" --data-ascii "status=[Nagios] $NOTIFICATIONTYPE$ $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$" http://twitter.com/statuses/update.json
}

define command {
command_name host-notify-by-twitter
command_line /usr/bin/curl --basic --user "twitteruser:twitterpassword" --data-ascii "status=[Nagios] $HOSTSTATE$ alert for $HOSTNAME$" http://twitter.com/statuses/update.json
}

Now define a contact for this twitter service into: contacts.cfg

define contact{
contact_name twitter
service_notification_commands notify-by-twitter
host_notification_commands host-notify-by-twitter
service_notification_period 24x7
host_notification_period 24x7
service_notification_options a
host_notification_options a
}

Add this contact into your existing contact groups like this (in contacts.cfg):

define contactgroup{
contactgroup_name admins
alias Nagios Administrators
members nagiosadmin,sms_alert,twitter
}

Then run a nagios prefly check to ensure you have no syntax errors, and restart nagios.

Perl – Zabbix SMS Allert

/ Daemon, Linux /

Un netmonitor, non è un vero netmonitor se non fa squillare il telefono del sysadmin con un sms almeno 3 volte a notte, ecco qui uno script in perl per interfacciare zabbix con il servizio fornito da Mobyt tramite un POST http su un loro gateway, con qualche aggiustatina può essere usato anche con altri servizi analoghi.

#!/usr/bin/perl

# Leonardo Rizzi
# Version 0.3
# SMS sent throuth Mobyt gateway
# Designed for use without ip autentication only MD5 Hash
# Attention: there aren't any check but message limit is of 160 charaters.

use Digest::MD5 qw(md5_hex);
use strict;
use LWP::UserAgent;
use HTTP::Request::Common qw(POST);
my ($operation, $qty, $rcpt, $query, $out, $ua, $ok, $ko, $data, $from);
my ($code, $id, $password);

$id="username";
$password="password";
$ok='SMS Sent Correctly';
$ko='SMS Not Sent';
$from= $ARGV[1];
$operation="TEXT";
$qty = 'h';

#attention this fuking provider don't accept 00 for international area code only + if you use 00 you get sent error
$rcpt = $ARGV[0];
$data = $ARGV[2];
$code = join '', $id,$operation,$rcpt,$from,$data,$password;

my $ticket=md5_hex($code);

$ua = new LWP::UserAgent;
$ua->agent("SMS_MD5_Relay/0.2 " . $ua->agent);
my $req = POST 'http://smsweb.mobyt.it/sms-gw/sendsmart',
[
id => $id,
operation => 'TEXT',
rcpt => $rcpt,
from => $from,
data => $data,
qty => $qty,
ticket=> $ticket
];

my $res=$ua->request($req);

if ($res->content =~ /^OK/)
{
fine_ok (); }
else
{ fine_ko (); }

exit;
sub fine_ko () {
my $msg=shift;
print "$ko\n";
exit (1);

}

sub fine_ok () {
my $msg=shift;
print "$ok\n";
exit (1);

}
