Pros & Cons
10 pros·6 cons across both
Datadog
+5-3
Pros
- Zero infrastructure setup—fully managed by Datadog with 99.99% uptime SLA
- 15-month data retention standard (vs 15 days for Prometheus)
- 600+ pre-built integrations with automatic agent discovery
- 24/7 enterprise support with SLA guarantees and dedicated account teams
- Advanced APM with distributed tracing across 100+ languages and frameworks
Cons
- Cost at scale: $15-$55 per host monthly, expensive for 500+ node deployments
- Vendor lock-in: switching costs high due to proprietary query language and data formats
- Data ownership concerns: all metrics stored on Datadog servers outside your control
Prometheus
+5-3
Pros
- Zero cost: completely free and open-source under Apache 2.0 license
- Complete data control: runs entirely on your infrastructure with no vendor dependency
- Flexible scrape model: pull-based collection reduces agent complexity and network overhead
- 800+ community exporters supporting virtually any software or hardware
- Simple query language (PromQL) easy to learn for basic to intermediate use cases
Cons
- 15-day default retention requires external storage solutions (Thanos, Cortex) adding 40+ hours setup time
- Community-only support: no SLAs, response times measured in days or weeks
- Infrastructure burden: requires Kubernetes/Linux VMs, persistent storage, and 2-4 engineers to maintain
Frequently Asked Questions
5 questions
Yes, Prometheus is production-ready and used by 62% of enterprises according to CNCF surveys. However, it requires implementing long-term storage solutions (Thanos, Cortex, or Mimir) since native retention is only 15 days. For high-scale deployments (1000+ metrics/sec), add 2-3 engineers to manage infrastructure. Datadog handles this automatically.
