Getting Started with OpenObserve
Compare the best telemetry collection agents in 2026 for logs, metrics, and traces on performance, footprint, and OTel compatibility.
Datadog Synthetic Monitoring bills per API and browser test run. Here's what that actually costs once you factor in check frequency, multiple locations, and journey count, with worked math and what a flat, usage-based alternative looks like.
We generated one billion log records, 2 TiB of NDJSON, and wrote the identical bytes into ClickHouse and two OpenObserve instances at the same time, each on its own dedicated node. Across 19 queries with a full-text index on both sides, OpenObserve finished 3.4x to 4.6x faster on a third less disk. One compaction setting was worth more than the file format.
We pushed the same ~2.2 billion samples through one OTel Collector into Prometheus, Grafana Mimir, and OpenObserve (Parquet and Vortex) simultaneously, then ran identical PromQL over a frozen 1.09-million-series dataset. OpenObserve answered irate queries ~15x faster, the million-series histogram ~6x faster, and held ingestion to half of Prometheus's memory.
ClickHouse and OpenObserve compared for observability: architecture, ingestion, RBAC and SSO, high availability, and cost at scale, for teams choosing what to build logs, metrics, and traces on.
ClickHouse's storage economics are genuinely excellent. Self-hosting a production observability platform on top of it isn't free, it's an engineering build. Here's what that build actually costs.
