Every notification jaque sends is one of these kinds. This page is the
catalogue: what fires each one, what silences it, what it does to the
escalation ladder, what PagerDuty and incident.io do with it, and what a
Nagios notification script sees in `$NOTIFICATIONTYPE$`.

| Kind | Fires when | Silenced by | Ladder | PagerDuty / incident.io | `$NOTIFICATIONTYPE$` |
|---|---|---|---|---|---|
| `PROBLEM` | a hard problem persists, repeating every `renotify_interval` | downtime, acknowledgement, unreachable parent, outside the period, `disabled_kinds` | counts toward `threshold`, escalates | `trigger` / `firing` | `PROBLEM` |
| `STATUS_CHANGE` | a hard problem changes status; not throttled | downtime, acknowledgement, unreachable parent, outside the period, `disabled_kinds` | counts toward `threshold`, escalates | `trigger` / `firing` | `PROBLEM` |
| `RECOVERY` | a hard problem ends | downtime, outside the period, `disabled_kinds` | resets | `resolve` / `resolved` | `RECOVERY` |
| `FLAPPING_START` | flapping starts | downtime, outside the period, `disabled_kinds` | untouched | not posted | `FLAPPINGSTART` |
| `FLAPPING_STOP` | flapping stops | downtime, outside the period, `disabled_kinds` | untouched | not posted | `FLAPPINGSTOP` |
| `ACKNOWLEDGEMENT` | an acknowledgement asks for it (the `notify` flag) | outside the period, `disabled_kinds` | untouched | `acknowledge` / nothing | `ACKNOWLEDGEMENT` |
| `DOWNTIME_START` | a window starts | outside the period, `disabled_kinds` | untouched | not posted | `DOWNTIMESTART` |
| `DOWNTIME_END` | a window ends | outside the period, `disabled_kinds` | untouched | not posted | `DOWNTIMEEND` |
| `DOWNTIME_CANCELLED` | a window is cancelled while in effect | outside the period, `disabled_kinds` | untouched | not posted | `DOWNTIMECANCELLED` |
| `CUSTOM` | an operator sends one by hand | downtime, outside the period, `disabled_kinds` | untouched | not posted | `CUSTOM` |
