I thought more on this over the weekend... what about organizing the utilities into subdirectories or prefixes that indicate whether they consume [SwingStore] SQLite files, slog files, or "other"? |

This is a grab-bag of tools I've assembled over the last few years, to analyze slogfiles for various things (mostly timing and leaks). Some in JS, some in Python. I wanted to get them off my local hard drive and into the tree where other folks could benefit from them. * monitor-slog-block-time.py : I use this on a follower node to print a one-line summary of each block, from the slogfile * prune-transcripts.js : I run this on a copy of the swingstore DB to delete all the old transcript spans, since most of my analysis doesn't need them, and it reduces the size by about 90%. * follower-run-tools/ : I use these to measure size data about the original and pruned DB. These tools are not TSC or eslint -clean: they use @ ts-nocheck and an .eslintignore to suppress complaints. Thanks to @gibson042 for all the helpful improvements.
