Night watch

Every server is checked every minute. When something goes down overnight, a watchdog agent tries a short list of safe fixes, like restarting a stopped service, and checks that it worked.

Then it sends one plain message: what broke, why, what it did, and whether anything is needed from a person.

In the field

• Checks every minute, day and night
• Only safe, reversible fixes
• One clear message, not a flood
