Commands
Generate Backfill Report
This command will produce a backfillReport.log file in the AUTOSOL MQTT logs. It will detail your current free RAM, free Disk Space, and the amount of time it would take to fill ram or available disk space if comms are lost.
Note: This report shows data based on current settings both AUTOSOL eACM and MQTT applications.
To see backfill to disk stats, make sure you have a SPB Publisher enabled with backfill to disk on.
This report uses a worst case scenario for the size of the tags estimated to be 12 Bytes / tag.
