The current HTML displays a snapshot of the FLASH and RAM usage for Linux example applications. To track usage trends over time, we need to collect and store daily FLASH and RAM data in a database (CSV). This data will then be used to generate a static HTML page that visualizes the daily FLASH consumption trends, similar to Time Series Charts in Looker Studio. |
Agreed, this PR is step 1, it scans all of the targets build in the OUT directory and collects flash and ram usage into a CSV file for a single day. I'm still not sure we should save multiple CSV files in disk. As I mentioned before, we are tinkering with the VM all the time and there's a high change this data will be wiped when we upgrade the VM or delete the disk for some reason. |

This PR adds a python script to analyze built targets and generate an HTML (or CSV) report of FLASH/RAM usage for each example app.
For now, this will run daily and provide and provide a snapshot or the FLASH/RAM usage in a table, similar to what has been done for conformance in (https://matter-build-automation.ue.r.appspot.com/conformance_report.html).
In the future, we plan to aggregate this data into a database and provide a better way to visualize historical data.
Testing
Tested it generates an HTML page locally. See screenshot below:
