dynatraceDeploying Dynatrace OneAgent Auto‑Injection in Kubernetes via a DaemonSet
Deploy the Dynatrace OneAgent as a DaemonSet so every node runs the agent, enabling automatic instrumentation of Java processes without code changes. One DaemonSet, a secret for the API token, and DT_TENANT is the minimal design.
kubernetesConfigure Dynatrace OneAgent on Kubernetes with the Dynatrace Operator for Full-Stack Monitoring
Automate full-stack OneAgent injection on Kubernetes using the Dynatrace Operator: create the secret, install via Helm, define a DynaKube CR, annotate namespaces, and verify metrics, traces, and logs flow to your tenant.
Automating Dependency Mapping in Dynatrace with OneAgent Full-Stack Monitoring
Learn how Dynatrace OneAgent automatically discovers services and builds real‑time dependency maps, with a concrete Java Spring Boot + PostgreSQL example and practical limits to consider.
Why Dynatrace's PurePath Changes How You Debug Microservice Latency
Dynatrace OneAgent's PurePath auto-instrumentation stitches requests across services without code changes. Here's how it helps debug latency, plus the overhead and coverage trade-offs.
Adaptive Sampling Latency Spike in Dynatrace OneAgent 1.239 Under High Concurrency
Goal: Identify the concurrent request load at which Dynatrace OneAgent 1.239’s adaptive sampling mechanism begins to add measurable request latency, given that the effect is driven by thread‑contention detection and varies with host CPU capacity. Constraints: The adaptive sampling threshold is not exposed in the UI, its default value differs across environme
Dynatrace OneAgent and Kubernetes Operator: Resolving the Injection Boundary in Production
Integration boundary A Dynatrace OneAgent configuration that connects in a local Docker Compose setup may not connect when the same application runs under the Dynatrace Kubernetes Operator. The local path typically relies on manually set DT_API_URL and DT_API_TOKEN environment variables. The production path depends on the Operator's mutating webhook and pod
Native memory leak in Java thread‑sampling sensor causing RSS growth in Dynatrace OneAgent
The goal is to ascertain whether the unresolved design decision around process‑group merging in Dynatrace OneAgent could leave native thread‑sampling buffers allocated after the leak fix introduced in version 1.225+. Observed RSS growth is tied to Java thread counts and only appears in releases prior to 1.225, but the fix notes do not detail the native buffe
javaTimezone conversion failed, falling back to UTC – OneAgent time‑zone handling
Error context The OneAgent health log emits the warning "Timezone conversion failed, falling back to UTC" when the host’s IANA time‑zone database is missing or outdated. This causes the agent to treat all host timestamps as UTC, shifting metric timestamps relative to local time. Goal: Ensure that metric timestamps remain accurate despite a missing or outdate
