check_chrome_driver_available_upgrade

Monitoring plugin to check if the Google Chrome stable debian package is upgradeable and a corresponding Google Chrome driver is available on Google Chrome Labs. Useful to maintain a Jibri installation up-to-date.

This plugin will do:

• update the APT cache if -U parameter is provided
• check if the google-chrome-stable package is available in APT cache (exit UNKNOWN otherwise)
• check if it's installed (exit UNKNOWN otherwise)
• run chromedriver --version command to retrieve Google Chrome driver installed version (exit UNKNOWN on error)
• check if google-chrome-stable package version match with chromedriver binary version (exit CRITICAL otherwise)
• check if google-chrome-stable package is marked as keep (only if -k / --check-mark-for-keep argument is provided, exit WARNING otherwise)
• check if an update is available (exit OK otherwise)
• retrieve the available Google Chrome driver from googlechromelabs.github.io API (exit UNKNOWN on error)
• check if the update version of google-chrome-stable package match with the available Google Chrome driver version (exit OK if not and exit WARNING if match)

This script could be used as Icinga/Nagios check plugin.
