Is it possible to filter out specific spans?

Yes, you can implement a custom SpanProcessor and pass it to useAzureMonitor to filter spans by kind or attribute before they are exported.

When should I call useAzureMonitor() in my application?

It must be called at the very beginning of your entry point file, before importing any other modules, to ensure auto-instrumentation hooks are applied correctly.

Can I use this for custom log ingestion?

Yes, the skill provides implementation patterns for the LogsIngestionClient to upload custom data structures to specific Azure Monitor tables.

How do I prevent high ingestion costs in production?

You can configure a samplingRatio (between 0 and 1) in the configuration options to limit the percentage of traces sent to Azure Monitor.

Does this skill support Node.js ESM (ECMAScript Modules)?

Yes, it includes patterns for using the --import loader flag required for ESM support in Node.js 18.19 and later.
