How we moved the OpenTelemetry Java agent to invokedynamic in 70+ pull requests
We did the same migration twice, three years apart, and the second time there were a hundred contributors instead of three. What changes when you rebuild how a Java agent instruments code and nothing in production is allowed to break.
Control how alerts activate, recover and notify: Kibana Universal Alerting in Elastic Observability
Turn ES|QL queries into alert data using Kibana Universal Alerting, and triage Classic and external alerts alongside Universal alerts in a single view.
YAML meets IConfiguration: Declarative configuration for the OpenTelemetry .NET SDK
You can change sampling without shipping a new build, because the first declarative configuration package parses YAML into a typed model and projects it into the flat keys the OpenTelemetry .NET SDK already reads.
No log file too small: How Elastic Agent tracks files below the 1 KiB threshold
Elastic Agent 9.5 builds a small log file's identity out of the bytes it already has, then re-links it as it grows and crosses 1024 bytes, so it is never re-ingested.
Telemetry Policy: change OpenTelemetry sampling and log levels at runtime, no restart
Telemetry Policy says what you want to happen and leaves each component to work out how. Change an OpenTelemetry Java agent's trace sampling to 1% and the JVM keeps serving traffic.
Native OTLP metrics ingestion on Elastic Cloud Hosted
Send an exponential OpenTelemetry histogram and Elasticsearch keeps the scale and buckets you sent. All four type and temporality combinations work now, and your SDK and Collector config stay exactly as they are.
LLM tracing in Elastic APM: prompts, responses, and token counts in the span view
In a twenty-call agentic trace, you can see which span is using the most tokens and read the prompt that caused it. Both live in Elastic APM, so there is no second tool to run.
OpenTelemetry Java extensions: customize traces without forking the agent
One JAR, loaded at startup by the OpenTelemetry Java agent, lets you filter health checks, rename spans, add resource attributes, and control sampling with no application code changes.
Elastic Agent now runs as an OpenTelemetry Collector: Less memory overhead, zero config changes
Elastic Agent 9.3 sends logs, metrics and traces through one OTel Collector pipeline, running Beats integrations alongside native OTel sources in a single Fleet-managed agent.
Correlate logs, metrics, and traces in one ES|QL query
Walk through four investigations, from CPU saturation to pod memory pressure, each answered by a single query across signal types.
vLLM Prometheus metrics for self-hosted LLM tuning: TTFT, KV Cache, and GPU Utilization
Tuning a self-hosted vLLM inference using its Prometheus metrics in Elastic Observability — TTFT, KV cache, prefix caching and DCGM GPU counters
Android application monitoring with OpenTelemetry: distributed tracing from tap to backend
EDOT Android adds mobile APM to your Android app with one Gradle dependency: crash reporting, session tracking and distributed tracing visible in Kibana.
