Track size of backups

[billglick]

It would be nice to track the size of the latest backup via telegraf. If the physical file size isn't possible, perhaps the count of items/files backed up could be useful.

puppet-profile_backup/templates/telegraf_backup.sh.erb

Line 1 in b9aa277

#!/bin/bash

The idea I'm looking for is to be able to alert if backups suddenly start shrinking compared to past ones, indicating that perhaps we are no longer backing up what we intended to. For example a system switches around the directories where files are stored that we need to backup.

The existing telegraf backup files_modified may be sufficient for what I'm wanting to track.

But it would be nice to have a new telegraf backup_size,backup_job=${backup_job} that shows the most recent backup archive size for each backup job.
