Dear Monks,

I have a script monitors a PBX that is streaming call data via specific port and saves this data to a database. The problem I am having is that the script does not notice when the PBX goes offline and will not reconnect when the PBX comes back online(some of these PBXes have programmed reboots in the night). I was wondering what would be the best way for me to add an "alive" type of check to this script to monitor if the PBX is alive and if not to keep testing until it does come alive again at which point it will reconnect to the streaming port. I assume we could use a ping type test for this maybe?

See current code below:

use DBI;
use strict;
use IO::Socket;
use POSIX;
# initialize host and port
my $host = shift || $ARGV[0];
my $port = shift || $ARGV[1];
my $proto = getprotobyname('tcp');
my $iaddr = inet_aton($host);
my $paddr = sockaddr_in($port, $iaddr);

for(;;){

my $sock = new IO::Socket::INET(PeerAddr => $host, PeerPort => $port,P
+roto => "tcp",)
or die "Cannot connect to PBX at address: $host port: $port: $!";

while (<$sock>) {
s/^\0+//; # Remove leading null characters
print $_;
chomp ($_);
#$_ =~ s/^[^ ]+//;
if ($_ =~m"/") {
&TXTout;    #send data to the data logging subroutine
&DBconnect; #send data to the database subroutine
}
} #Close While loop

sub TXTout {  
my $dir = "/var/log/smdr/";   # please ensure you create this director
+y to get your log files
my $filename = strftime("%B%d%Y",localtime(time));
my $fileexpression = $dir.$filename;
if (-e $fileexpression){
open(FILE, ">>$fileexpression");
print FILE $_;
close (FILE);
}
else {
open FILE, >$fileexpression;
print FILE $_;
close (FILE);
}
}

sub DBconnect {
# MySQL Connection parameters
my $dbuser= "root";
my $dbpassword= "Adm1n!";
my $dbhost= "localhost";
my ($line, $mon, $day, $stime, $pm, $hrs, $mins, $sec, $callp, $leaddi
+git, $callno, $speed, $callp2, $transf, $acccode, $sysid, $tester);

            $mon = substr ($_, 1,2);
            $day = substr ($_, 4,2);
            $stime = substr($_, 7,5);
            $pm = substr($_, 12,1);
            $hrs = substr($_, 14,2);
            $mins = substr($_, 17,2);
            $sec = substr($_, 20,2);
            $callp = substr($_, 23,4);
