OneAgent 1.299 is the last version supporting OneAgent Extensions 1.0 framework. You can continue using OneAgent Extensions 1.0 if you stay at OneAgent version 1.299. Note that this means you'll be using an unsupported Python version 3.8. We strongly recommend migrating your extensions to the latest Extensions 2.0 framework.
For environments with Extensions 1.0, the OneAgent version 1.301 rollout starts after Oct 31, 2024.
The log agent security rules have been relaxed to allow greater flexibility in log file handling. This change supports a broader range of use cases, as described below:
Each include rule now adds an optional rotation suffix ([-._]*) at the end of the filename. This means filenames can have suffixes for rotation without requiring explicit configuration.
Log files are now permitted within a log or logs subdirectory at any directory level. Subdirectory names are now more flexible, allowing variations such as logfile, logfiles, and applogs.
The previous block on files in the /usr/ directory is lifted, provided the standard log directory or extension conditions are met.
Log files with a .txt extension are now allowed, broadening compatibility for text-based log formats.
These changes don't impact the rules for autodetection of log files, which remain the same.
OS Services events enrichment
Infrastructure Observability | Hosts
Events generated by OS Services settings will now be enriched with the dt.settings.object_id member used to identify settings used to raise an event uniquely.
Java module automatically traces incoming Kafka messages based on @KafkaListener annotation
Infrastructure Observability | Hosts
The OneAgent Java module now automatically traces incoming Kafka messages if an application uses a meta-annotation using Spring's @KafkaListener annotation.
Automatic log enrichment if JMX remote is enabled
Infrastructure Observability | Hosts
The OneAgent Java module now automatically enriches loglines if an application uses SLF4J, JMX remote is enabled, and the JUL LogManager is active.
Apache subrequests handling improved
Infrastructure Observability | Hosts
Apache subrequests (including mod_dir usage) are now properly handled, preventing potential OneAgent crashes.
VxFS support added
Infrastructure Observability | Hosts
We have added support for disks using the VERITAS File System (VxFS).
Infrastructure event enrichment
Infrastructure Observability | Hosts
Events generated by infrastructure settings will now be enriched with the dt.settings.object_id member, which identifies settings used to raise an event uniquely.
DiskEdge event enrichment
Infrastructure Observability | Hosts
Events generated by Disk Edge settings will now be enriched with the dt.settings.object_id member, which identifies settings used to raise an event uniquely.
