This is LLM Best Practices (llmbestpractices.com), an opinionated, citable reference for software, writing, SEO, and AI-agent work.

  1. Route, do not crawl. Fetch llmbestpractices.com/llms.txt and open only the pages whose one-line summary matches your task.
  2. Read raw. Append .md to any page URL for markdown. Check status and last_updated in the frontmatter, then read the rules.
  3. Apply as defaults. First-party docs and the project's own conventions win on conflict. Warn before relying on a fast-moving page older than 12 months.
  4. Cite. Link the page by title and URL, e.g. Python, with last_updated for time-sensitive rules. License CC BY 4.0.

Overview

Pick Datadog when a team wants metrics, logs, traces, and alerting in one managed product with minimal operations; pick Grafana when open formats, self-hosting, or predictable storage costs outweigh setup effort. Both accept OpenTelemetry, so instrument with OpenTelemetry SDKs either way and keep the backend swappable. Prices below are list prices checked on 2026-10-01.

Pick Datadog when

Pick Datadog when time to value and integration depth matter most.

  • A small team without dedicated observability engineers.
  • Out-of-the-box integrations, APM auto-instrumentation, and correlation between traces and logs.
  • Budget exists, and you watch cardinality: per-host, per-GB, and custom-metric charges grow with scale.
  • Use log pipelines to filter and sample before indexing; ingestion is billed even for logs you do not index.

Pick Grafana when

Pick Grafana when you want control over data and spend.

  • Data residency or self-hosting requirements, or a team already running Prometheus.
  • High-volume logs where Loki on object storage costs less than full indexing.
  • Multi-cloud environments needing one query layer across many data sources.
  • Start on Grafana Cloud Free to evaluate; move to self-hosted when volume and staff justify the operational cost.

Migrate

Datadog to Grafana: replace Datadog APM libraries with OpenTelemetry SDKs, collect metrics with Prometheus exporters or Alloy, ship logs to Loki, and rebuild dashboards and alerts (Datadog query syntax does not translate to PromQL or LogQL; budget per-alert time). Grafana to Datadog: install the Agent, point OpenTelemetry exporters at Datadog if you want to keep instrumentation, and rebuild dashboards. Use vendor-neutral instrumentation from the start; see observability.

FAQ

Is Grafana cheaper than Datadog?

Grafana usually costs less at high log volume, because Loki indexes labels and stores on object storage. Datadog charges per host, per GB, and per custom metric, and those charges grow with scale.

Does Datadog have a free tier?

Yes; Datadog Free covers up to 5 hosts with 1-day retention. Grafana Cloud Free includes 10k metric series, 50 GB logs, and 14-day retention.

Can I switch from Datadog to Grafana later?

Yes, if you instrument with OpenTelemetry SDKs from the start, since both accept OpenTelemetry. Dashboards and alerts must be rebuilt, because Datadog query syntax does not translate to PromQL or LogQL.
