rpi-info-monitor

A simple, configurable application and set of services to monitor multiple raspberry pi's on a network. It can be used in a terminal or a web UI.

There are three components:

1. rpimonitor - A module used to format and display the information about each pi into a terminal or web UI (can be viewed vertically or horizontally)
2. rpimonitorapi - A flask API that runs on each pi to communicate information about the running proccesses and resources
3. webdisplay - A flask service that can be used to host the front end web UI. It can be installed on the main pi or another machine, but is not required

NOTE: The web UI (webdisplay) depends on the rpimonitor module. It is suggested to install the module or keep these two folders in the same directory if you want to run the web UI. Otherwise you will need to add the rpimonitor module to your PYTHONPATH

Installation/Usage:

1. Install the flask service on each pi by running the install.sh script as root or setting up the services manually
2. On your main pi/machine that will be used to run the display, modify the HOSTS variable in rpimonitor/config.py with the host names and local IPs of your pi's
3. After modifying the configuration, you can install using the setup.py: python3 setup.py install
4. Install the required python modules on the main pi/machine (pip install -r requirements.txt)
5. You can then install the rpi-info-webapi service if you want to use the web UI (if using the web UI, you can get better formatting for mobile by installing the flask_mobility package)
6. To run the display loop in a terminal, use python3 -m rpimonitor --run-forever [options]

Confiugration:

The config.py file in the rpimonitor directory/module is used by the web UI and command line utility. The below configurations are available:

• HOSTS - A list of dictionaries that contain 2 keys: 1) "hostname" - the host name of the pi and 2) "local_ip" - the local IP address of the pi
• SERVICES - A list of services (names of proccesses) to display in the services panel
• COUNT_DISPLAY_SERVICES - A list of names from SERVICES that will display the number of running processes instead of Running/Stopped
• WIDTH - Character width of each panel (height is automatically adjusted)
• VALUE_SPACING - Character position of the status values in each panel
• API_PORT - The web API port that will be used on each pi
• PCT_RED_THRESH - The threshold used to color numeric values as red
• SLEEP_TIME - The time to sleep between each refresh (when using -r/--run-forever in the terminal)
• TEMP_UNITS - Units that the CPU temperature will be displayed in (fahrenheit/celsius)
• MAX_TEMP - Maximum temperature (fahrenheit)

Examples:

Command:

$ ./display.sh or $ python3 -m rpimonitor

NOTE: You can pass --no-color to not include coloring in the terminal display
