From Alert Noise to Actionable Signals: Lessons from Production
Explore latest insights and updates
A complete guide to log levels: what DEBUG, INFO, WARN, ERROR, TRACE, and FATAL actually mean, how log level hierarchy and filtering work, and best practices for choosing the right level in every environment.
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.
An observability customer story showcasing how Uno.ai, an AI-native agentic platform for GRC and enterprise risk, unified telemetry across GCP, AWS, and Azure while curbing rising cloud-native monitoring costs with OpenObserve.
Error budgets explained: how they work, how to write an error budget policy, and what actually happens when the budget runs out.
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.
OpenObserve's reliability release: native SLOs with error budgets and multi-window burn-rate alerting, grouped alerts that track each host or metric series independently, and bidirectional Terraform and GitOps support for observability as code, managing alerts, dashboards, and SLOs as code.
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.
The cost curve of availability: what each nine allows in downtime, what it costs to build, and why most services should target fewer nines.
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.
A side-by-side comparison of Grafana and Datadog on pricing and features, and where OpenObserve fits as a unified alternative to both.
Learn why Kubernetes incidents take too long to resolve and how to reduce MTTR through temporal and dimensional correlation of logs, metrics, traces, and Kubernetes Events.
A practical deep-dive into OpenTelemetry context propagation: the W3C Trace Context spec, traceparent and tracestate header anatomy, baggage, propagators, and why distributed traces break across services.
A practical, attribute-by-attribute guide to OpenTelemetry's GenAI semantic conventions: the gen_ai.* namespace for spans, metrics, and events, stability levels, a worked instrumentation example, and common migration mistakes.
What is observability, and how is it different from monitoring? A complete guide covering the three pillars (logs, metrics, traces), the properties that make a system observable, maturity stages, and how to get started.
A complete comparison of the best synthetic monitoring tools in 2026: HTTP, TCP, TLS, SSH, and browser checks, private location support, alerting, and pricing, for engineering, SRE, and platform teams.
A complete, practical guide to OpenTelemetry Collector configuration: YAML file structure, receivers, processors, exporters, pipelines, environment variables, validation, and common mistakes.
A complete comparison of the top LLM observability tools in 2026, open source and commercial, covering tracing, evaluation, cost tracking, and unified infrastructure monitoring for AI engineering teams.
Synthetic monitoring runs scheduled checks from outside your systems; RUM captures what real visitors experience. Learn what synthetic monitoring is, how it differs from RUM, and when to use each.
Synthetic Monitoring is now in beta in OpenObserve Cloud: HTTP, TCP, TLS, and SSH checks with per-type assertions, full Playwright browser checks from a no-code recorder or your own scripts, and Private Locations to reach internal endpoints, all landing in the same platform as your logs, metrics, and traces.
