This module checks reachability of webservers. You can map a list of urls to their expected http status codes and a list of email addresses to inform if one of the url does not return the expected status code. A check interval is also configurable.

• Configurable interval to check for expected http status codes
• Can be run on any linux machine (minimal dependencies)
• Configure an email address to get notified if any resource doesn't work as expected or isn't even available.

Run this script to initialize the watcher.

./reachableWatcher.sh

to enable the checking logic. After running:
