# Personal node heartbeat probe

Runs on `JD-OPS-CENTER` and checks one registered node through a private SSH
alias. The remote action is fixed and read-only: service state, disk usage and
uptime. A JSON receipt is written under `/var/lib/guanghu/receipts/` every five
minutes.

Real addresses and SSH identity paths belong in `/etc/guanghu/nodes/ssh/config`
on the ops center, never in this repository.
