 <meta itemprop="description" content="Probe Introduction In SkyWalking, probe means an agent or SDK library integrated into a target system that takes charge of collecting telemetry data, including tracing and metrics. Depending on the target system tech stack, there are very different ways how the probe performs such tasks. But ultimately, they all work towards the same goal — to collect and reformat data, and then to send them to the backend.
