The words up4 uses, each in one line. Names in the app are the ones you see on screen.

## Accounts and access

- **Company:** The top-level account. It owns the monitors, members, billing and credit; everything else sits inside one Company.
- **Team:** A group of members inside a Company. A Team decides who can see and change what.
- **Client:** A customer of an agency. Clients keep monitors, scheduled jobs, status pages and reports apart. They exist once agency mode is switched on.

## Checking

- **Monitor:** One target that up4 checks on an interval: a website, a port, a DNS record or a ping.
- **Check:** One run of a monitor from one region. It ends as up or down and records how long the answer took.
- **Region:** A place checks run from: Europe, North America, Asia or Australia. See [checks and regions](https://upfour.io/docs/how/checks-and-regions#regions).
- **Interval:** The time between two checks of a monitor.
- **Keyword check:** A website check that also reads the page and looks for a word that must, or must not, appear.
- **Scheduled job:** A task that runs on your side and reports to up4\. up4 raises the alarm when the report stays away.
- **Check-in:** The short request a scheduled job sends to its up4 address to say it ran.
- **Grace period:** Extra time a scheduled job gets after its expected time before up4 counts the check-in as missing.

## States and timing

- **Up and down:** A monitor is **up** while checks succeed and **down** once they fail.
- **Degraded:** **degraded**: the target answers, but slower than expected. up4 only warns about it when slowdown alerts are on.
- **Pending:** **pending**: a monitor that has no result yet.
- **Paused:** Checks are stopped on purpose, so a paused monitor sends no alerts.
- **Confirmation:** up4 changes a monitor's state only after 3 matching results, so a single failed check does not alert you.
- **Confirmation period:** Optional extra time a failure must last before it counts as an outage. It applies on the way down only.
- **Recovery period:** How long a monitor must stay healthy before the outage counts as over.
- **Availability:** The share of checks that succeeded in a period, also called uptime.
- **Response time:** How long a check waited for the answer.

## Alerting

- **Alert channel:** A way up4 reaches you, such as email, SMS, a call, a chat app or a webhook.
- **Alert plan:** Steps with wait times and repeats that bring in people one after another until someone acknowledges.
- **Alert mode:** Per monitor: **Right away** alerts once an outage is confirmed; **Skip short blips** waits for a longer outage in total.
- **On-call rotation:** A schedule that says who is on call when. An alert plan can page whoever is on call.
- **Acknowledge:** **Acknowledge**: tell up4 you have seen an incident. It promises neither a takeover nor a fix.

## Incidents and status pages

- **Incident:** The recorded outage, from the first confirmed failure to the recovery, with its timeline.
- **Resolve:** **Resolve**: close an incident once the cause is fixed.
- **Playbook:** Reusable steps for fixing a known problem, shown on the incident.
- **Maintenance window:** A planned period in which up4 skips checks for a monitor, so planned work does not alert you.
- **Status page:** A public page that shows the state of the monitors you choose, plus your status reports.
- **Status report:** A message you post on a status page during an incident or maintenance.

## Credit and plans

- **Starting credit:** The credit a new Company starts with, €9. Checks use it up. When it is gone, monitoring pauses until you add credit or choose a plan.
- **Wallet:** Your prepaid balance. You top it up, and checks draw from it.
- **Grace mode:** After a first payment, an empty balance does not stop monitoring at once: for 7 up4 checks every 5 minutes at no charge, then pauses.
- **Allowance:** The usage a Team or Agency plan includes each month.
- **Add-on:** Extra capacity you can add to a plan. See [add-ons](https://upfour.io/docs/reference/limits#addons).
