Thank you for this suggestion. I’m afraid that would be somewhat complicated to build. The plugin uses Javascript to “throttle” calls to www.remarpro.com’s plugin API. When recent data is not available for some (or all) plugins, the script fires off calls one-by-one, waiting until a previous call’s data arrives before firing the next. This is why you can the lines update sometimes.
Since there’s not always a complete set of data in the database (there may in fact be no data at all), supplying the data to wp-cli would require doing something similar in PHP. Either that, or a manual action (refreshing in wp-admin) would be required before usign wp-cli.
Of course, you could use the CSV export to process further (locally?).
