  2. Delete the directories:
    • /var/log/dynatrace/oneagent
    • /opt/dynatrace/oneagent/
    • /var/lib/dynatrace/oneagent
  3. Install OneAgent version 1.259.339 again.

New features and enhancements

New code-level vulnerability ID

Application Security | Attacks

Starting with OneAgent version 1.259, code-level vulnerability ID calculation has changed. After updating the OneAgent, all existing code-level vulnerabilities that are based on the restarted process will be closed and new ones will be opened if the code-level vulnerability is still present. This does not affect third-party vulnerabilities.

Host uptime metric

Infrastructure Monitoring | Hosts

OneAgent now reports the Host uptime metric (builtin:host.uptime). Metric isn't available for application-only deployments.

Node.js module can capture BizEvents

Infrastructure Monitoring | Hosts

Now available: The OneAgent Node.js module can capture BizEvents based on incoming web requests.

Grouping of oneagenthelper process

Infrastructure Monitoring | Hosts

(Linux only) The oneagenthelper process is now assigned to the OneAgent system monitoring process group.

Grouping of oneagenteventstracer process

Infrastructure Monitoring | Hosts

The oneagenteventstracer process is now assigned to the "OneAgent system monitoring" PGI.

Grouping of MongoDB executables with names containing version number

Infrastructure Monitoring | Hosts

MongoDB executables with names containing a version (for example, "mongod-4.0") are now detected as members of the MongoDB group.

PostgreSQL instance name now displayed as node in PGI name

Infrastructure Monitoring | Hosts

PostgreSQL process group instance names are now displayed as "Postgres (INSTANCE_NAME)" in the web UI. The default value of INSTANCE_NAME is Default instance.

Simultaneously use OneAgent and OpenTelemetry exporters for Java

Apps & Microservices | Distributed traces

When you deploy OneAgent to automatically collect OpenTelemetry span data for Java, existing OpenTelemetry exporters are no longer suppressed by OneAgent. OpenTelemetry spans collected and integrated with end-to-end distributed traces spans by OneAgent, can now be sent by an OpenTelemetry exporter to third-party backends, such as Jaeger, without disturbing existing OpenTelemetry and third-party backends.
