The automatic instrumentation for Node.js is now (since version 0.48.0) more configurable.
Most of us don’t want the fs-instrumentation package active, because it creates dozens or hundreds of spans that we don’t care about. There’s a bunch of files opened when an app spins up, the first time it opens a TCP connection, and more.
It used to require a code change to turn it off, but now the automatic instrumentation will listen to an environment variable! I highly recommend setting
OTEL_NODE_DISABLED_INSTRUMENTATIONS=fs
