Meet the product

Design the system that watches everything else: thousands of hosts push numeric samples every few seconds, engineers query dashboards, and alert rules page on-call when something is wrong. It must absorb spikes, keep alerts firing while dashboards are slow, control cost as data ages, and not be brought down by one bad label.

Step 1 of 14 · Intro

Design a metrics and monitoring system

Ingest millions of samples, keep dashboards snappy and wake humans only when it matters.

How it works

›Ingest: agents push batches of timestamped samples (write-heavy).
›Query: dashboards read ranges, repeatedly and in bursts.
›Alert: rules are evaluated continuously on the same data.

What you'll build

The API and the series schema
A buffered, batched write path
A cache for dashboards and a separate consumer group for alerts
A quota against cardinality bombs
A design that survives losing a store node, a consumer and a cold cache
