how to check if agent has started span, if not how can I start span?

[annaik-mdsol]

I run my springboot app with otel agent, I want to ensure that agent creates span if not I want to create span for my app. I have created loggingContextFilter in springboot, how to see span starting and if not create one and then process doFilter?

I think Span.current().getSpanContext().isValid() is what you're looking for
