Did you find a solution @rallapallisagar ?
Can you open with some words what you are exactly trying to do?
Sure we have some Azure functions running with C# or Java code there for we have some custom log statements they go into the Eventhub and than to Splunk but Splunk have a problem with the format which comes from the Eventhub (nested jsons) eventhough the log messages are microsoft standard...
Ithink the best way to start to collect azure event logs is read these two articles
https://www.splunk.com/en_us/blog/tips-and-tricks/getting-microsoft-azure-data-into-splunk.html
https://www.splunk.com/en_us/blog/platform/splunking-azure-event-hubs.html
However, if these articles aren't enough, please don't hesitate to ask
