If users pass e.g.
sampleRate: process.env.SAMPLE_RATE
, this will be somewhat silently ignored because we ignore non-number sample rates. This is a bit of a footgun.So this PR changes this so that we actually accept such sample rates. In the process, I also removed the
isNaN
polyfill as this is not really needed anymore.I also updated OTEL to use the same sampling function as core (to avoid this drifting apart), and am using this for
sampleRate
,tracesSampleRate
and the replay sample rates now.See e.g. #11262
