Recommended way to monitor sealed/unsealed status?

[cpick]

I have a vault-operator-installed cluster that I'm monitoring with Prometheus. The StatsD exporter provides some metrics, but I am looking for a way to track the number of sealed/unsealed vault instances. (For example: I'd like to trigger an alert when a certain number of nodes are unsealed.)

I know that vault-operator keeps the VaultService resource's "status" section up to date with this information, but I haven't found a convenient way to get this information into Prometheus.

I've found the vault_exporter tool, perhaps that can be installed as a sidecar alongside the StatsD exporter?

@cpick - the Banzai Cloud Vault operator does monitor this (and other stuff as well), with charts, etc included. You might want to check this post: https://banzaicloud.com/blog/monitoring-vault-grafana/

I created PR #347 with the solution I landed on.
@matyix if we didn't already have a CoreOS vault-operator installation and we were installing from scratch I think we would go with Banzai Cloud Vault operator. It seems to be more feature complete and, more importantly, actively maintained :(
