root_monitoring

This is monitoring files written in Perl. I use them on Amazon Linux.

It checks server resource and daemon status and sends e-mail.

Usage

Set up

1. update monitoring/config.pl to adapt to your server.
2. sudo file/root_setup.sh development ap for development application server
   sudo file/root_setup.sh development mail for development mail server
   sudo file/root_setup.sh production ap for production application server
   sudo file/root_setup.sh production mail for production mail server
   You can execute the above command everywhere.
   Then, required Perl files are copied to root directory.

Feature

This checks resource and service status.
root_setup.sh set the crontab to execute resource_check.pl every 3 minutes and service_check.pl every day.

for Application Server

• Service Check: check nginx status, and when they're down, reboot them and send mail.

for Mail Server

• Service Check: check saslauthd and postfix status, and when they're down, reboot them and send mail.

for Every Server

• Resource Check: send the results of df -h and free -m as e-mail.

Customization

• If you want to check another services, change root_setup.sh and service_check.pl.
  • root_setup.sh defines programs to be checked according to the server type (ap or mail).
  • service_check.pl defines program information to be checked.
