RPi-Monitor

Raspberry Pi utility written in NodeJS that emits alerts periodically to a Hermes server with device status.

RPi-Monitor is a command line utility:

• it can be run manually at anytime
• it's scheduled to be run every 5 minutes by a cron job

RPi-Monitor uses Hermes nodejs library, this means that if internet connection is available to the RPi, the alerts are guaranteed to reach Hermes server.

Requirements

• cron installed on RPi
• Hermes server configured and available
• RPi in ready state (Project id, Kronos id and Hermes Url must be assigned) - See RPi Status docs

RPi is distributed via NPM:

sudo npm install -g --unsafe-perm @p4d/rpi-monitor

Notes:

• -g - Global flag is required so that the utility is accessible from anywhere in the system.
• --unsafe-perm - This flag is required to set up the cron job for sudo user.
