OneAgent release notes version 1.235

Rollout start: Mar 7, 2022

With this release, the oldest supported OneAgent versions are:

Standard Support

Enterprise Success and Support

Java

  • Added support for TIBCO ActiveMatrix BusinessWorks 6.6 - 6.8

.NET Framework

    • Starting with this release, we support the .NET Core code module on Linux ARM64 (AArch64).
    • The file location for Event Tracing for Windows (ETW) temporary file has changed to faster temporary storage in Microsoft Azure environments.

    .NET and .NET Core

      Starting with this release, we support .NET Core code module on Linux ARM64 (AArch64).

      Node.js

      New features and enhancements

      IBM App Connect Enterprise (IBM Integration Bus)

      • Added tracing support for IBM App Connect Enterprise JavaCompute node. To enable this as a OneAgent feature
        1. Go to Settings > Server-side service monitoring > Deep monitoring.
        2. Expand the New OneAgent features section, find IBM Integration Bus tagging for JavaComputeNode, and turn it on.

      IBM z/OS

      • oneagentzos-R12350.pax is now available

      • Added support for the IMS service provider to z/OS Connect Enterprise Edition. It allows tracing of outgoing requests from z/OS Connect Enterprise Edition to IMS programs via IMS connect. For details, see Install OneAgent for Java on z/OS.

      • Added tracing support for CICS transactions that start on a terminal (green screen transactions). For details, see CICS terminal transaction start filter.

      • Added support to DTAX enable/disable Language Environment sensor. For details, see Enable DTAX Language Environment Sensor.

      • IMS SOAP Gateway and CICS Transaction Gateway process IDs could change after each server restart, which would result in new process and service entities. To prevent this problem, we’ve introduced a more stable process ID calculation, with the consequence that all existing IMS SOAP Gateway and CICS Transaction Gateway process and service entities will change once but then remain stable after an update of the z/OS Java code module with OneAgent version 1.235.

      IMS SOAP Gateway process IDs

      Because IMS SOAP Gateway process IDs could change after each server restart, resulting in new process and service entities, we’ve introduced a more stable process ID calculation with the consequence that all existing IMS SOAP Gateway process and service entities will change once but then remain stable after an update of the z/OS Java code module to version 1.235.

      Linux/AIX deployment.conf

      To tighten data security, Linux/AIX deployment.conf is no longer readable by others. Permissions for config files in /var/lib/dynatrace/oneagent/agent/config are reapplied during every update.

      Installation streamlining

      Starting with this release, an upgrade of OneAgent will reuse the previous Winpcap/Npcap instead of reinstalling it.

        General

        • OneAgent memory dump process (oneagentdumpproc) no longer fails when started manually if a thread in the target process exits while oneagentdumpproc is attaching. (APM-336518)
        • Corrected potentially incorrect metadata provided via metadata file in case a standalone OneAgent installation is used. (APM-351024)

        OS module

        • Fixed recalculation of process group instance (PGI) ID in an endless loop for PGI with custom environment variables. (APM-355354)
        • Fixed OSI ID for EC2 and Azure hosts when HostIdSource is set to k8s-node-name. (ONE-69816)
        • OneAgent OS module now sets its file descriptor limit based on the number of processes on the host. (APM-341259)
        • For declarative process grouping matching, the first part of the process command line (which sometimes is changed by the process to provide additional information) is now added to command line arguments. (APM-345664)
        • OneAgent System Monitoring component will continue working, even if can't attach to shared memory. (ONE-70679)

        Plugin module

        • Vulnerability: The aiohttp library used in the Docker extension has been updated to version 3.8.1. (APM-345850)

        All modules

        • Fixed a bug in SQL normalization for the "ESCAPE '\'" clause. The normalizer now correctly detects that case, so it does not mask the remainder of the string. (ONE-71653)

        Infrastructure Monitoring

        • Vulnerability: Restricted access to configuration files in RPM installation. (APM-344965)
        • OneAgent metric interface is now properly initializing when ingest port is open (resolves an issue with empty tiles, missing data). (APM-352922)

        OpenTracing Java

        • The CICS Transaction Gateway process IDs could change after each server restart, which would result in new process and service entities. To fix this problem, we’ve introduced a more stable process ID calculation, with the consequence that all existing CICS Transaction Gateway process and service entities will change once but then remain stable after an update of the z/OS Java code module to version 1.235. (ONE-70277)

        Java

        • Resolved JDBC-related class-loading issue for Mule applications using Java 9 or later. (ONE-69158)
