Changes
This PR adds a counter
app.payment.transactions
that can be split by the transaction currency, adds dependencies to the JS Metrics packages, and changes the startup process so that the async resource detection can finish before creating aMeter
orTracer
.Once updated instrumentation packages are released, I will open a follow-up PR that updates the metrics API/SDK to the GA versions. Then the added temporality environment variable will also change the temporality of the exported metrics accordingly. 🙂
