Monitoring mysql tables in perl

[kamal]

So here is what i want to do: Monitor a bunch of tables in a MySQL database, append time stamps to WHEN the values changed, and then render the result in a graph.

1. Is there a tool/utility that somewhat does this already ( I could not find it ) 2. i used DBI, and was able to connect to the database and get some table column values:

#!/usr/bin/env perl

use strict;
use warnings;
use Net::SSH::Perl;
use DBI;

my $database = 'co_sysdev';
my $server = 'devqa_dbm.corp';
my $user = 'username';
my $passwd = 'password';
my $row = "";
my $homologs = DBI->connect("dbi:mysql:database=co_sysdev;host=devqa_d
+bm.corp;port=3310",'username','password');
# prepare an SQL statement

#my $query_params = "select * from system_params";
# render the result in a graph format
# save it locally in a csv format, to be used later for report
my $query_coding_event = "select * from coding_event";
my $query_params = "select * from co_event";
#my $query = "select * from n_batch where status = 'started'";
#my $query = "select * from n_batch"; 
#my $query = "select id,customer_id,location_id,submitter,n_notes,hand
+le from submission_batch where id is not null"; 
#my $query = "select id,customer_id,location_id,submitter,n_notes,hand
+le from submission_batch where id is not null"; 
#my $query = "describe submission_batch"; 
#my $query = "show tables";
my $sql_params = $homologs->prepare($query_params);

# execute an SQL statement

$sql_params->execute();

# retrieve and print results

while (my $row = $sql_params->fetchrow_arrayref) {
    #print join("\t", @$row), "\n";
    print join(@$row), "\n";
    print @$row . " \n";
}


# Break connection with MySQL database

$homologs->disconnect;

exit;

This seems to be such a common use case, that i am surprised there arnt many scripts/packages available for the same.
