| # Field Data |
| |
| Ledger uses [Cobalt] to record field data. |
| |
| In order to add more events: |
| |
| - edit Ledger code under [/bin/ledger/cobalt] |
| - register the new events, see documentation for [Cobalt client] |
| |
| In order to view the recorded data, run: |
| |
| ``` |
| cd src/cobalt/bin |
| ./download_report_client.py |
| ./report_client -project_id=100 |
| ``` |
| |
| Then, follow `report_client` hints to extract the data. For example, run the |
| following to extract Ledger event counters from the last 5 days: |
| |
| ``` |
| Command or 'help': run range -4 0 2 |
| ``` |
