Integrate EBAM data with RPI-Monitor

Closed this issue · 2 comments

We're using RPI-Monitor to visualize system health/history of the underlying hardware. It's pretty easy to add metrics to this system and we want to add

  • new dynamic metrics corresponding to EBAM measurements
  • new panel on Status page showing
    • latest measured value
    • latest measurement timestamp
    • bonus points for nice image
  • new plots on Statistics page for EBAM measurements

The configuration should be encapsulated in a new RPI-Monitor config file. See examples here

To actually access EBAM measurement values, use this two-step approach:

  1. data retrieval script writes measurement values into individual files located in RAM
/run/ebam/pm25

10.3
  1. use cat to read values from those same files by specifying source like so:
...
dynamic.N.source=cat /run/ebam/pm25
...

To keep EBAM-specific config separated, put entries into new file /etc/rpimonitor/template/ebam.conf and add that file to include list at bottom of /etc/rpimonitor/data.conf:

...
include=/etc/rpimonitor/template/ebam.conf
