I'm testing your tool for the last 24 hours and as I already said, it's really nice but the problem that is's consuming a lot of space.

In my case, after a bit more then 24h of it running, it's already using 14GB of space for reports (puppet is running every 30min on nodes) with 10k+ reports generated daily. Most of the reports are "unchanged", which I think could easily be remove since they don't contain any useful data (at least for me).

A solution could be an option to delete reports, when status is unchanged. When puppet uploads the reports, it pulls out data it needs (status, timestamp, execution time,...) for sqlite db and then remove it. In case status is failed/changed, it would save it.
This also means there would be no link to reports if status is unchanged in node details.

What do you think?
