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

Papertrail

  • Log Observability starts at $5.00 per GB per month
  • Usage beyond the plan volume is billed at a 30% higher price per GB and is capped at 200% extra
  • Transferred volume is measured as message length plus 50 bytes of metadata per message, so metadata counts against the quota
