The scheduled maintenance window in force at a moment, if any, so alerts and uptime can be suppressed during it.

Combine the statuses of one target's probes from several locations into one up, degraded or down, with a quorum.

Turn a series of up, degraded and down checks into incidents, ignoring runs too short to confirm.

One bar per UTC day for a status page's uptime history: seconds in each state, uptime and a colour state, oldest first.

Time-weighted uptime of a target over a window from its checks, with gaps longer than a limit counted as unknown.

Classify one HTTP probe as up, degraded or down, with a reason and message, from status, body and latency.

The overall state, headline and affected components at the top of a status page, from each component's state.

A status page component's state from its checks: operational, degraded, partial or major outage, or maintenance.

A TLS certificate's expiry state as a check status: ok and warning are up, critical is degraded, expired is down.

The samples of a time series from one moment up to (not including) another, checking they are in time order.

Multiwindow, multi-burn-rate SLO alerting: which rules fire, from event counts per window (Google SRE workbook).

Evaluate a threshold alert rule over a metric series: inactive, pending, firing or no-data, Prometheus style.

How much of an SLO's error budget is allowed, used and left, from good and bad event counts or seconds.

How much a monotonic counter grew over a series of samples, counting restarts from zero, and its rate per second.

Step an alert through inactive, pending, firing and resolved, and say which notification to send.

Aggregate a metric series into fixed time buckets (count, min, max, avg, sum, last), empty buckets included.

A number of seconds as a short human duration for dashboards and alerts: "3h 12m", "2d 4h", "45s".

How fast an SLO's error budget is burning: the error rate as a multiple of the rate the SLO allows, in thousandths.

Validate one network inventory entry: name, host, ports, optional MAC and subnet, with every problem listed.

Parse one Apache/NCSA Common or Combined Log Format access log line; null for a line in neither format.

Count HTTP status codes by class (1xx to 5xx) and give the server error and client error rates in basis points.

How long a TLS certificate has left before its notAfter, and whether that is ok, a warning, critical or expired.
