Simple Uptime Monitor

A multithreaded server monitors pings sent from multiple clients and alerts if such a sensor went down (stopped sending pings)

Consider a simplistic Pingdom, if you will.

How to set it up

1. Check your Perl version in a shell with
   perl -v
   Note: This project has been tested on a Unix box with Perl v5.16.2; YMMV.
2. Clone this repo or download the zipped archive
   https://github.com/sagz/Perl-TCP-Ping-Monitor/archive/master.zip
3. Profit.

Usage

There are two parts, server and client(s)

1. Run the server first. By default, it listens on port 42424.
   $ ./server.pl
   Command line arguments: $ ./server.pl [port]
   The server accepts an optional commandline argument for the port to listen on. An integer between [1-65535]
2. Now run a client. By default, it tries to connect on 127.0.0.1:42424 with 'ping' frequency of 1 second and client name as the machine's hostname.
   $ ./client.pl
   Command line arguments: $ ./client.pl [server_IP] [server_port] [frequency] [self_name]

Example Run

$ ./server.pl

And two+ separate shells with:
$ ./client.pl 'localhost' 42424 2 'Hans'
$ ./client.pl 'localhost' 42424 10 'Chewbacca'

Features

• Multi Threaded
• Lightweight (Server memory footprint <1MB, with 50 clients running)

To - Do

• Sanitize command line arguments
• ANSI Colour output!
• Rigorous testing suite
