Datadog collects metrics, logs, traces, and uptime checks from servers, containers, and serverless functions, then puts them behind one query language and one alerting system. Agents install in minutes and the integration catalogue covers most managed services. For a distributed system, having the trace and the log line for the same request in the same view is the difference between a five-minute fix and an hour of guessing, and the agent installs in minutes.
Who it is for
Platform and SRE teams running multi-service production systems.
Key features
- Infrastructure metrics with dashboards
- APM traces across services
- Log ingestion with live tail
- Synthetic uptime and browser checks
- Alerts routed to Slack and PagerDuty
Where it falls short
Billing compounds across hosts, custom metrics, log ingestion, and every add-on product, so a bill can double without anyone changing the architecture.
Pricing
Per-host pricing for infrastructure plus separate metered charges for logs, traces, and each add-on; a free tier covers a few hosts.
Prices move; the tier structure is the part that stays true. Check current pricing on Datadog.
