PhpWatchDog 1.16.7

PhpWatchDog is a network monitor application which provides a simple way to check if a service (HTTP, FTP, SSH, etc.) is running or not. PhpWatchDog project can send email to the servers administrator to report malfunctions.
This little script is running into my servers from some time (even from two years!). Its very usefull to alert a system administrators team by email. Its a PHP script, so you can setup a cronjob that run the URL of phpwatchdogs installation when you want (I suggest every hour).
Main features:
- check if service is UP or DOWN
- no need to install anything into monitored servers
- report to one email address if service is DOWN
- simple and light
- easy to install and configure
- can set the timeout for probing the service status
- can use fsockopen (PHP) or IO::Socket (PERL) - if for any reasons the fsockopen can operate correctly
- can monitor n servers with a single instance
- can alert a custom email address per server
- to work properly need only APACHE+PHP, no databases or various plugins
- collect each downtime event into a plain text file
Installation:
unpack the downloaded archive
# tar jxvf phpwatchdog-*.tar.bz2
enter into phpwatchdog/ directory and edit the config file (config.php)
# cd phpwatchdog
# nano config.php
Note: here you can see nano, that is an easy to use text editor, but I strongly encourage to learn to use vim (the enhanced version of vi)
put your servers into config.php
$i++;
$config[Servers][$i][host] = 66.35.250.203;
$config[Servers][$i][server_name] = www.sourceforge.net;
$config[Servers][$i][service][1] = 80;
$config[Servers][$i][service][2] = 443;
Every server configuration block must begin with the line "$i++;"
customize your email account for alert reporting into config.php
fire up your browser and go to phpwatchdog installations path
