consul-snapshot is a backup and restore utility for Consul (https://www.consul.io). This is slightly different than some other utilities out there as this runs as a daemon for backups and ships them to S3. Also has integrated monitoring and backup health checks.
If it's anything like some of the other Hashicorp projects I would assume that you'd want to use go-metrics
Do you have any idea what operations you want covered by metrics? If not - I'm sure I can figure some out.
Just looking for something I could conceivably contribute for a project that looks like it could work in our environment as well.
Let me know and I'll see what I can do!
