2024-03-20 - Cribl Stream 4.5.1 | Maintenance Release | Edge 4.5.1 release notes are here.

New Features​​

This release provides the following improvements:

Sources and Destinations​

Google Pub/Sub Source can now subscribe to topics in a project on a different service account. Similarly, Google Pub/Sub Destination can publish to topics in a different service.

Amazon S3 Destination offers an additional storage class: Glacier Instant Retrieval. Other storage classes are renamed for clarity and to match the names used by S3: “Glacier” is now “Glacier Flexible Retrieval”, while “Deep Archive” changed to “Glacier Deep Archive”.

Health Check Collector now returns an elapsedMS attribute in __collectStats.

Windows Event Forwarder Source now contains Field settings. Additionally, you can configure fields per subscription.

Splunk HEC, HTTP/S, and Elasticsearch API Sources now log time-based metrics about incoming requests and ingested events.

In the Raw HTTP/S Source you can now add request headers to events, in the __headers field.

Other New Features​

New C.Misc UUID functions (C.Misc.uuidv4, C.Misc.uuidv5, C.Misc.validateUUID, C.Misc.getUUIDVersion) let you generate a UUID for each event and validate it.

Corrections​

This release includes the following fixes:

  • Fixed a bug in the Raw HTTP Source where the event.headers field only replaced the first hyphen in a header name with an underscore instead of the intended behavior of replacing all hyphens with underscores. CRIBL-23106

  • Special characters < > " ` \r \n \t { } | \ ^ ' in authToken when managed Workers are being deployed using the CRIBL_DIST_MASTER_URL (for example, in containers) will now correctly throw an error. Such characters can’t be used in the token. CRIBL-17047

  • Corrected a memory leak on Workers. CRIBL-22804

Source and Destination Fixes​

  • Cribl TCP, Cribl HTTP, and TCP JSON Sources and Destinations now respond with more meaningful messages in case of connection problems. CRIBL-16537

  • Syslog Source now correctly respects the Default timezone setting. CRIBL-23031

  • Cribl TCP, TCP JSON, and Appscope Sources now log stats once per minute to the metrics.log file. CRIBL-21742

  • Fixed an issue with the Google Pub/Sub Source which caused it to run out of memory. CRIBL-20424

  • Kafka Destination now outputs a timestamp field based on __kafkaTime. If __kafkaTime is not present, the timestamp defaults to Date.now(). CRIBL-22966
