Dealing with raw strings or unstructured messages is a constant pain; having a structure is highly desired. If you don't use `Time_Key' to point to the time field in your log entry, Fluent-Bit will use the parsing time for its entry instead of the event time from the log, so the Fluent-Bit time will be different from the time in your log entry. The parser With over 15 billion Docker pulls, Fluent Bit has established itself as a preferred choice for log processing, collecting, and shipping. FluentBit Inputs. Optionally, we provide debug images for x86_64 which contain a full shell and package manager that can be used to troubleshoot or for testing purposes. 12 we have full support for nanoseconds resolution, So for Couchbase logs, we engineered Fluent Bit to ignore any failures parsing the log timestamp and just used the time-of-parsing as the value for Fluent Bit.
