Hello,
I am in the same case than you @madhavink14 .

The most recent post I found regarding what we want to achieve is:
https://dustinvannoy.com/2024/01/07/monitoring-databricks-with-log-analytics-updated/
It is based on this spark-monitoring repo:
https://github.com/dvannoy/spark-monitoring/tree/l4jv2_jars/target
Currently, by following this tutorial, I am able to have some log4j logs to be collected into a log Analytics workspace inside the sparkLogginEvent_CL table (spark-monitoring doesn't log to App Insights), but those logs have to come from a Notebook (tested with scala and python notebook).

So for now, logs that are done in a Jar file are not collected...
