Yamon software monitors server health & alerts users of downtime or issues. It facilitates checking of server uptime and sends notifications to the user if the server is down.
It is important to note that Yamon is not an "enterprise grade system monitoring solution." As such, it may not be suitable for large corporate networks or professional ISPs. For those types of applications, Nagios would be a more appropriate choice. Also, Yamon does not create graphs or track trends - it simply notifies you when there's a problem. However, for individual users with one or two systems to monitor, Yamon is highly effective and user-friendly.
To get started with Yamon, you need a Unix-based system that can run it as a cron job. The machine must be able to send email using the "mail" command-line utility. You'll also need a working Perl installation and an Internet connection. There is a download link in the sidebar, along with basic documentation in the archive.
One useful feature of Yamon is its ability to send real-time alerts to your mobile phone via an e-mail to SMS gateway. This lets you know if something is wrong with your system no matter where you are.
The latest release of Yamon includes the check_dnsbl test, which alerts users when their monitored servers get listed on a DNS-based blacklist (like bl.spamcop.net or SORBS). Overall, Yamon is an effective and easy-to-use solution for individuals who want to monitor their systems and stay informed of any issues.
