Where each one falls short

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

Dynatrace Logs

  • Log ingest and processing is billed at $0.20 per GiB, separately from retention and from query
  • Querying logs is charged in addition to ingest, either pay per query or as bundled queries
  • Log analytics requires the same annual platform commitment as the rest of the Dynatrace platform

Fluent Bit

  • Fluent Bit ships over 100 built in plugins against more than 1,000 external plugins available for Fluentd, so fewer integrations exist out of the box
  • It is written in C, so extending it beyond the built in plugins means writing C rather than Ruby
  • Dependencies are zero only until a plugin requires one
