dak.graph_new

Generate an HTML page and PNG charts wih the age of packages in NEW

To be run once a day.

The tool stores persistent status in the RRD database and the pickeled queue in order to speed up daily runs. Directories and database files are created as needed.

If the RRD directory is deleted the script rebuilds past years from the historical logs, and that can take a while, otherwise it just parses fresh data.

init_rrd(rrdfn, t)	Initialize empty RRD
main([verbose_debug])
plot_graph(out_dir, fname, rrdfn, start, ...)
process_events(events, last_update, ...)	Process logged events like ACCEPT-TO-NEW, ACCEPT, REJECT and update the RRD database accordingly
skip_file(fn, last_update)	Skip files that are already processed
