Where each one falls short

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

Fluentd

  • Fluentd needs more than 60 MB of memory at runtime, against roughly 450 KB for Fluent Bit
  • Fluentd is built as a Ruby gem and depends on other gems, so a Ruby runtime is required
  • Its capability comes from over 1,000 external plugins rather than built in functionality, so each added input or output is a separate dependency
  • The Fluent Bit documentation states that cloud providers have switched from Fluentd to Fluent Bit for performance and compatibility and calls Fluent Bit the next generation solution

New Relic Logs

  • Log data counts against the same 100 GB monthly free ingest allowance shared with every other telemetry type, so logs compete with metrics and traces for it
  • Ingest beyond that is $0.40 per GB, rising to $0.60 per GB on the Data Plus option
  • Full platform users cost $349 each a month on Pro with an annual commitment, or $418.80 paying monthly
  • The Standard edition caps additional full platform users at 5
  • Core users are $49 a month each even though basic users are free
