New in version 3.19.0
A health endpoint monitor can now be told that a part is failing on purpose. Mark it as expected, a staging database for example, and Nightbell stops paging about it while it keeps that status. The first change to it pages you again. The monitor's screen is rebuilt around this: what needs you, what you marked as expected and what is healthy, each in its own group.
Mark expected sits on the failing part's row, and in the sheet that opens when you tap the part, which now holds its rules and log.
Point Nightbell at anything that answers over HTTP, or at one element on a
rendered web page, and it watches it, charts it, and gets loud when it
breaks.
There is no server and no account. The phone in your pocket does the
checking, and your API tokens and target URLs never leave the device.
Three kinds of monitor:
- Status check: hit a URL, assert on the status code.
- Request and response: pick the method, set headers and a body, assert
on what comes back (contains, equals, regex, or a JSON field by path).
- Page element: load the real page in an embedded browser and watch DOM
nodes you picked by tapping them.
Urgent alerts arrive as a full-screen red page with a looping alarm that
keeps going until you acknowledge it, and it wakes the screen even if the
phone is locked. A first-launch screen walks through the four Android
grants a paging app actually needs (notifications, unrestricted battery,
full-screen intent, Do Not Disturb access), because two of them have no
system dialog and have to be opened by hand.
A home-screen widget shows the worst monitor first. Settings let you shape
the alert policy: what counts as down, sound, haptics, escalation, and
quiet hours.

New in version 3.18.0
Nightbell can now read a health report your service writes about itself. Instead of only knowing that a server answered, it shows which part is in trouble, the rule that decided it with the value it measured, and what the service saw along the way. The overall verdict pages you; the rest is there when it does.
The new Health endpoint monitor signs in the way your own clients do: a fixed header, basic auth, or single sign-on through your web app, a username and password, a service account or a p

New in version 3.16.0
Outages can now be posted to a team, not only to this phone. Nightbell sends them to Microsoft Teams, Slack, Discord, Google Chat, ntfy, Gotify, Telegram, or any address with a body you write yourself, straight from the phone with nothing in between. Each webhook keeps the failure threshold and cooldown your alerts use, so a flaky endpoint does not flood a channel.
Add one under Settings, Alerts, Webhooks. Choose what it hears about (down, still down, back up, slow, an expiring certificate, Git
