Fluent Bit vs Dynatrace Logs
The short version
- Each has a real cost: 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; Dynatrace Logs log ingest and processing is billed at $0.20 per GiB, separately from retention and from query
- They diverge on capability: Fluent Bit covers Log collection, Dynatrace Logs covers Log analysis.

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