There's similar instructions here
for metrics, but the concepts / env-vars should have analogs for tracing.
You can either disable at the source (each app w/ instrumentation SDK) by setting the
exporter to none.
or change one of the
intermediate collectors to use a
nopexporter for the traces pipeline. Although I can't tell if that's available in the
signoz-otel-collector responsible for writing to Clickkhouse.
