New features and enhancements
Feature update 
Infrastructure Observability | Log Monitoring
Custom encoding support in OneAgent
OneAgent can now be configured to ingest and decode logs that lack a BOM marker that defines the encoding method or the use of a specific encoding for diacritical characters. The supported encodings are UTF-8, UTF-16 Little and Big Endian, Shift_JIS (Japanese language), and EUC_KR (Korean language).
Feature update Infrastructure Observability | Hosts
Declarative process grouping and deep-monitored processes
Starting with OneAgent version 1.307, deep-monitored processes are supported by declarative process grouping in Full-Stack Monitoring, Infrastructure Monitoring, and Discovery modes on OneAgent installer-based deployments and in Kubernetes classic full-stack deployment.
For other deployments, declarative grouping is supported for processes that aren't deep-monitored.
For details, see Declarative process grouping.
Feature update Infrastructure Observability | Hosts
Added new field "Container image digest"
The "Container image digest" is now retrieved, persisted, and shown on the container properties page.
The containerImageDigest was added to the semantic dictionary. This field is written based on the observability level.
Prerequisites:
- Kubernetes platform monitoring with ActiveGate requires ActiveGate version 1.291+ and the new Kubernetes experience to be enabled for that cluster.
- Application observability or Infrastructure observability requires OneAgent version 1.307+.
The new field is written in addition to the existing fields containerImageId and containerImageName.
Feature update Infrastructure Observability | Hosts
Unified exe path normalization in Process Groups and Process Groups Instances on Windows
Detected exe paths of process on Windows will be normalized to upper case.
Feature update Infrastructure Observability | Hosts
Improved disk alerting sensitivity
Starting with this release, when a network drive is used or a disk is shared by multiple hosts (VMware datastore / Windows / Linux SMB / NFS or Amazon EFS) there’s only one alert/event created for the related problems. We do not create alerts for each mount point of a single disk.
Feature update Infrastructure Observability | Hosts
Declarative Process Grouping supports deep monitorable processes
Declarative Process Grouping supports deep monitorable processes. Deep monitored metrics will start to show on declarative grouping PGIs.
Feature update Infrastructure Observability | Hosts
Improved services and network disk detection on Linux
We have optimized OS Services and network disks detection on Linux.
Feature update Infrastructure Observability | Hosts
Log Agent supports systemd journal logs
OneAgent can now collect logs from Journald on Linux systems.
- This functionality is switched on by default on new tenants.
- On existing tenants, you need to enable it manually: go to Settings > Log Monitoring > Log module feature flags and turn on Enable Journald log detector.
Feature update Application Observability | Mainframe
IMS Connect is now visible as a Process Group Instance
OneAgent now displays IMS Connect as a PGI. This improvement makes IMS Connect:
- Visible in PurePath traces and Service flow.
- Shows native system performance metrics on the PGI.
Feature update Infrastructure Observability | Hosts
Introduced security software detection
The following security software is detected by OneAgent: Carbon Black EDR (on Windows only), CrowdStrike Falcon XDR, Trellix Endpoint Security (former McAfee).

RUM
- Fixed an issue in which, if an element had multiple CSS classes and Visually Complete used the CSS class attribute as a selector, it incorrectly concatenated the classes, which caused the Visually Complete waterfall finding to display the CSS selector for the key element incorrectly. (DEM-3052)
- If a request made by the JavaScript agent gets an invalid/failed response, it will only make Session Replay stop recording if the request was from Session Replay, excluding resource captures. (DEM-4128)
Session Replay
- Resolved an issue in which the JavaScript agent, when forced or being used as a fallback, failed to load the D module in the UI thread instead of in a worker, disabling Session Replay. (DEM-3279)
