Combined the history and status scripts for each data backend and moved some of the shared code into a separate module. Since the existing script names were not appropriate for the new combined versions, the main entry point scripts now have new names, which better conform with Python module name conventions: dish_grpc_text.py, dish_grpc_mqtt.py, and dish_grpc_influx.py. pylint seems happier with those names, at any rate.
Switched the argument parsing from getopt to argparse, since that better facilitates sharing the common bits. The whole command line interface is now different in that the selection of data groups to process must be made as required arg(s) rather than option flags, but for the most part, the scripts support choosing an arbitrary list of groups and will process them all.
Split the monster main() functions into a more reasonable set of functions.
Added new functions to starlink_grpc to support getting the status, which returns the data in a form similar to the history data functions. Reformatted the starlink_grpc module docstring to render better with pydoc. Also changed the way sequence data field names are reported so that the consuming scripts can name them correctly without resorting to hacky special casing based on specific field names. This would subtly break the old scripts that had been expecting the old naming, but those scripts are now gone.
The code is harder to follow now, IMO, but this should allow adding of new features and/or data backends without having to make the same change in 6 places as had been the case. To that end, dish_grpc_text now supports bulk history mode, since it was trivial to add once I had it implemented in order to support that feature for dish_grpc_influx.
Since "current" got added to the global data group returned from getting the history stats in non-bulk mode, it was being output by all 3 of the history scripts, and the name "current" was a little confusing when looking at prior output, since old values would no longer be current. The description of it in the start param of history_bulk_data was confusing, too.
Add tracking of exactly which samples have already been sent off to InfluxDB so that samples are neither missed nor repeated due to minor time deltas in OS task scheduling. For now, this is only being applied to bulk mode.
Make the -s option only apply to the first loop iteration for bulk mode, since subsequent loops will want to pick up all samples since prior iteration.
Also, omit the latency field from the data point sent to InfluxDB for samples where the ping drop is 100%. The raw history data apparently just repeats prior value in this case, probably because it cannot just leave a hole in the data array and there is no good way to indicate invalid.
Related to issue #5
Specific history data patterns would sometimes lead to some of the stats switching between int and float type even if they were always whole numbers. This should ensure that doesn't happen.
I think this will fix#12, but will likely require deleting all the spacex.starlink.user_terminal.ping_stats data points from the database before the type conflict failure will go away.
Unlike the status info scripts, these include support for setting host and database parameters via command line options. Still to be added is support for HTTPS/SSL.
Add a get_id function to the grpc parser module, so it can be used for tagging purposes.
Minor cleanups in some of the other scripts to make them consistent with the newly added scripts.
Move the "samples" stat out of the ping drop group of stats and into a new general stats group.
This way, it will make more sense if/when additional stat groups are added, since that stat will apply to all of them.
Moves the parsing logic that will be shared by some upcoming scripts out into a separate module.
There's still just as much duplication between the JSON parser and the grpc parser as there was before, but this should at least prevent further duplication of this logic.
This also adds some proper documentation for what each of the stats means.
