Suggestion.

  • Angel is a simple yet useful tool to monitor the services on your network. Technically speaking, it's a Perl program that runs every 'n' minutes (usually fired from your cron) and calls different perl subprograms (referred as "plugins" ) to do the actual testing. It will then generate an HTML table containing the status of your network.

The CMU distribution for SNMP is a great place to start if you really want to master network management.... you need to master:

  • SNMP
  • UNIX Syslog
  • The C Programming Language
  • PERL, PHP, PYTHON or other SCRIPTING language.
  • TCP/IP client-server......
  • and a whole lot more !!!
