Instruments war file into tomcat.

[saursharma-equinix]

I have seen some doc to instrument war into tomcat

export CATALINA_OPTS="$CATALINA_OPTS -javaagent:/path-to-where-jar-is-downloaded/opentelemetry-javaagent.jar"
export OTEL_METRICS_EXPORTER=none
export OTEL_EXPORTER_OTLP_ENDPOINT=OTELcollectorIP:port < or Copy from other instrumentations that you have running already, basically IP:port>
export OTEL_RESOURCE_ATTRIBUTES=service.name=<app_name>

But it won't work. I am unable to see the traceId or spanId.
