Observability icons

The 18 observability icons in DevOps, described

Alertalert

An alert — something fired, a notification raised or a page sent out.

Alert rulealert-rule

An alert rule — the condition that has to be true before an alert fires.

Brownoutbrownout

A brownout — still on, just less of it, a service degraded to stay up.

Error budgeterror-budget

An error budget — how much failure an SLO allows you before you have to stop shipping.

Flame graphflamegraph

A flame graph — where the time actually went, stack by stack in a profile.

Health checkhealth-check

A health check — the probe that asks whether a service is still alive and answering.

Latency trendlatency-trend

A timer dial with a rising line on its face — how response time is trending.

Load sheddingload-shed

Load shedding — better to drop some requests than sink the whole service.

Loglog

A log — what happened, written down as it happened, entry by entry.

Log streamlog-stream

A log stream — lines arriving live as they happen, tailed and followed.

Observabilityobservability

Observability — being able to see what a system is doing through logs, metrics and traces.

Packet losspacket-loss

Packet loss — one of the packets never arrived, a gap in the network stream.

Queue depthqueue-depth

Queue depth — how much work is waiting right now, the backlog height.

SLAsla

An SLA — the service level agreement, a promise with a signature on it.

SLIsli

An SLI — the service level indicator you actually measure, such as latency or error rate.

SLOslo

An SLO — the service level objective you hold yourself to, the target for an indicator.

Tracetrace

A trace — one request followed through every service it touched, span by span.

Uptimeuptime

Uptime — how long a service has stayed up and available without an outage.

In code, each is one import — import { Alert } from "@iconmind/react/icons/alert" — and the same name in Vue, Svelte, Solid, Preact, React Native, Astro, Blade and Flutter.
