This release addresses three critical issues found in Cribl Insights:

  • Fixed an issue introduced in 4.16.0 where, on Cribl.Cloud, events sampled by the Data Insights Profiler (an internal profiling component) added two internal fields, __diProfileStartNs and __diProfileDITimeNs, that could not be serialized to JSON. When these fields reached certain Destinations, JSON serialization failed with the error Do not know how to serialize a BigInt, which could lead to backpressure warnings and dropped events in Cribl HTTP and Cribl TCP Destinations, their destination persistent queues, and Pipelines that serialized these internal fields. (NUG-568)
  • Fixed an issue where the Data Insights flow map could fail to load the first time after a Leader restart or after Data Insights had been idle for some time, returning an error from the Insights API while subsequent reloads succeeded. (NUG-561)
  • Fixed an issue in 4.16.0 where Hybrid Workers did not enable Data Insights. As a result, Data Insights metrics were missing for affected Hybrid Worker Groups. (NUG-569)
