Allow customization of name for traceId value in Java MDC

Instana automatically populates the MDC with the trace ID. The MDC variable name is instana.trace.id. See https://www.ibm.com/docs/en/instana-observability/current?topic=technologies-monitoring-java-virtual-machine#logging-mdc-populated-with-the-trace-id


We want a way to customize that mdc variable name. For example, we want to customize so that MDC variable name is instana_trace_id instead of instana.trace.id. Perhaps allow passing something like this to the java process: -Dcom.instana.mdcName=instana_trace_id

    Hello,

    Thank you for suggesting the improvement in our Product.

    While we see this level of customization could be valuable for both of us, because of our current load, we realise we cannot come to this request in the near future.

    Please re-open the request in 12 months if this request is important to you.


    Thanks again,

    Mary Reni Rajaian

    Some reasons:

    • to maintain APM vendor neutrality/transparency as much as possible

    • to follow internal logging convention on how MDC keys should be formatted (dotted vs underscored)

    Thanks for reaching out, I am curious why would you like to do so? Have you encountered parsing problem when we are using dot as delimiter?
