HiveMQ is an open source MQTT broker that provides secure and reliable data transfer between IoT devices and downstream applications, enabling visibility into the health of IoT infrastructure. Datadog's HiveMQ integration collects metrics and event logs from HiveMQ, providing out-of-the-box dashboards for visualizing and alerting on key data. The Distributed Tracing Extension enables users to instrument their workloads to generate OpenTelemetry-formatted distributed traces, which can be sent to Datadog Application Performance Monitoring (APM) for enhanced visibility into application performance. With HiveMQ's OTel-instrumented traces and Datadog's support for OpenTelemetry, users can quickly spot issues in IoT application performance, identify root causes, remediate user experience problems, and understand how their applications interact with each other within their broader infrastructure.
