Monitoring tools are good at noticing that something broke. Getting that news to a person is the part that goes wrong: the alert lands in an inbox, a channel nobody watches at night, or an app that was logged out last week.
Hookfire takes the alert your monitor already sends and makes it a push notification, so the first person to hear about the outage is you, not a customer writing in to ask whether the site is down.
The one that should wake you. Mark it high priority and it breaks through Focus modes.
Just as useful: it tells you whether you still need to get out of bed.
When a rotation exists, the escalation is the moment the first responder did not answer.
A new error is a bug. The same error at five times its usual rate is an incident.
Each of these sends the events above. Setup is the same for all of them.
