Prometheus metrics from openssh

ssh2prom

Annoyingly simple daemon that tails the ssh journal and exports failed root login attempts.

Exports the following metrics:

• ssh_failed_total{family="1|2"}: all failed attempts (including root)
• ssh_failed_root_total{family="1|2"}: failed attempts where the user is root
• ssh_sucess_total{}: all successful logins

The total also includes the root user, the root_total is the subset that counts root only. If family is 1 it's a connection over IPv4, with 2 it's IPv6.

Every occurence of Failed password for .... from .... port ... ssh2 is counted as a failed attempt. Every session opened for user is counted as a success.

It tails the log using the 'fuck you' (-fu) option of journalctl.
