Best remote host monitoring tool for fedora 6

I need remote host monitoring tool (open source) for my fedora 6 box. I want to monitor the remote host by pinging the IP address of the remote host if the remote host down means the monitoring soft should send mail or sms to the system admin.

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

If you want a SIMPLE monitoring tool, which it sounds like you do, check out Big Brother.

Nagios is an excellent monitoring tool, and supports very complex installations.  Big Brother is another excellent monitoring tool, and is better suited to more moderate or basic installations.

If your initial goals is just to monitor ICMP, life will be _much_ easier, to configure Big Brother, and you'll find answers for most questions more readily.  Nagios is really aimed more towards someone who has exceeded the abilities of BigBrother, and is willing to invest substantial amounts of time/effort into making it work right.

Nagios will work, it's just overkill, and Big Brother will take less time/effort.  I've used both.  For simple installs, I use BB.  I start to look at Nagios for 10-15+ host installs with custom services (more than just CPU/disk/ping monitoring, and services like FTP/WWW/SMTP/etc.), or extensive customization requirements (e.g. for complex pager rotation schedules).
