Best when you want predictable per-host APM
Try DatadogNew Relic's data-based pricing rewards efficient instrumentation but punishes teams with verbose logging or high-cardinality metrics. Datadog Pro at 15 dollars per host per month is predictable: you know what your bill will be from your infrastructure size. For teams whose New Relic bill keeps surprising them on the data side, Datadog's per-host model is more forecastable. The trade is a higher entry cost and a more complex pricing matrix across additional products.

Migration steps
- Audit New Relic dashboards and alerts; export your APM service list and key metrics.
- Sign up for Datadog and install the Datadog agent on the same hosts.
- Recreate your most-used dashboards in Datadog; the metric query language differs but covers the same shape.
- Rebuild PagerDuty or Slack alert routes in Datadog, run two weeks of parallel coverage, then turn off New Relic agents.
Not for: Skip Datadog if your data volume already fits under New Relic's 100GB free tier; the math reverses for small teams.
