OpenObserve
Open-source observability platform (logs, metrics, traces) built in Rust as a single binary. OpenObserve claims 140x lower storage costs than Elasticsearch for similar workloads. Provides a Grafana-like UI, OpenTelemetry ingestion, SQL querying over logs, and alerting. Self-hosted alternative to Datadog/New Relic with zero licensing cost. Also offers a managed cloud version.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Open source for full auditability. Self-hosted keeps all observability data in your infrastructure — strong data sovereignty. TLS configuration is responsibility of deployer. RBAC available.
⚡ Reliability
Best When
You're cost-conscious, comfortable self-hosting, and need full-stack observability (logs + metrics + traces) with SQL querying and OpenTelemetry support at dramatically lower storage costs.
Avoid When
You need managed enterprise support, extensive out-of-the-box integrations, or you're comparing to a team that already runs Grafana stack effectively.
Use Cases
- • Ingest and query agent application logs with SQL queries over structured JSON logs without per-GB ingestion pricing
- • Collect OpenTelemetry traces from agent services for distributed tracing with significantly lower storage costs than Datadog
- • Alert on agent error rates, latency thresholds, and anomalies using OpenObserve's built-in alerting with scheduled queries
- • Correlate logs, metrics, and traces from agent infrastructure in a single platform at self-hosted cost
- • Replace expensive SaaS observability (Datadog, New Relic) for agent infrastructure with full-featured open-source alternative
Not For
- • Teams requiring enterprise SLAs and support without self-hosting expertise — Datadog, New Relic, or managed Grafana Cloud provide managed support
- • Organizations needing battle-tested enterprise observability with extensive integrations — Datadog has a much larger integration ecosystem
- • Windows-primary environments — OpenObserve is Linux/container-native
Interface
Authentication
API key (email:password base64) or Bearer token authentication. Organization and stream-level permissions. Self-hosted auth configured during setup.
Pricing
Apache 2.0 / AGPL v3 licensed. Self-hosted is free with no limits. Cloud tier has generous free tier. Dramatically lower total cost of ownership than Datadog at similar capabilities.
Agent Metadata
Known Gotchas
- ⚠ OpenTelemetry endpoint paths differ slightly from standard OTel spec — verify endpoint configuration in collector/SDK
- ⚠ SQL dialect for log queries has some limitations compared to standard SQL — test complex queries before relying on them in production
- ⚠ Self-hosted requires S3-compatible object storage for data persistence — local disk storage is for development only
- ⚠ Compaction and retention policies must be configured explicitly — no auto-retention without configuration
- ⚠ OpenObserve version upgrades can require schema migrations — test upgrades in staging before production
- ⚠ Alert delivery requires external notification configuration (Slack, email, webhook) — not included by default in self-hosted
