The short version

  • Each has a real cost: Elastic APM pricing is not published on the product page; cost follows the underlying Elastic deployment rather than being quoted per host or per service; Logstash logstash's source is dual licensed: code outside the x-pack directory is Apache License 2.0, but code inside x-pack (which carries several of Logstash's monitoring and management features) is licensed under the Elastic License, not a fully open source license
  • They diverge on capability: Elastic APM covers Performance monitoring, Logstash covers Data ingestion.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Elastic APM

  • Pricing is not published on the product page; cost follows the underlying Elastic deployment rather than being quoted per host or per service
  • Self-managed deployment means running and scaling Elasticsearch yourself
  • Serverless does not carry every capability the hosted option does

Logstash

  • Logstash's source is dual licensed: code outside the x-pack directory is Apache License 2.0, but code inside x-pack (which carries several of Logstash's monitoring and management features) is licensed under the Elastic License, not a fully open source license
