Quick Recommendations by Use Case
Cost-conscious startup
New Relic (100 GB free) or Grafana Cloud (free tier)
Both offer generous free tiers that cover small teams. New Relic gives full platform access. Grafana Cloud gives the open-source experience without maintenance.
Kubernetes-native team
Prometheus + Grafana (self-hosted) or Grafana Cloud
Prometheus was designed for Kubernetes. It is the native monitoring solution with the deepest integration. Grafana Cloud manages it for you.
Enterprise (100+ servers)
Dynatrace or Grafana Cloud Pro
Dynatrace's auto-discovery and AI-powered root cause analysis reduce toil at scale. Grafana Cloud Pro offers cost-predictable pricing without per-host fees.
Log-heavy environment
ELK Stack (self-hosted) or Splunk
Elasticsearch provides the best full-text log search. Splunk is the gold standard for log analytics. Both handle high-volume log environments better than usage-priced alternatives.
Debug-focused team
Honeycomb
Honeycomb's BubbleUp analysis and high-cardinality query engine are designed for debugging complex distributed systems. Best for teams that need to ask arbitrary questions of their telemetry data.
Maximum cost savings
Self-hosted Prometheus + Grafana + Loki
$0 in software costs. $200-$2,000/month in hosting. Requires 10-20 hours/month DevOps maintenance. Best savings for teams with available SRE capacity.
