What each one is

The product in its own terms, so the numbers below have context.

GreptimeDB

A columnar database designed for observability workloads that accepts metrics, logs, and traces via standard protocols like OpenTelemetry and Prometheus Remote Write. It supports SQL queries for all data types and PromQL for metrics, using object storage for cost-effective long-term retention while keeping recent data in fast local caches.

Independently observed

Prometheus

Leader

A pull-based monitoring platform that periodically scrapes metrics from instrumented targets over HTTP and stores them in a time-series database. It provides PromQL for querying metrics and integrates with Alertmanager for rule-based alerting and incident notifications.
