F5 integration with SumoLogic

Hello,

I am trying to integrate F5 LTM with Sumo as explained in these links:

https://www.f5.com/pdf/deployment-guides/f5-analytics-dg.pdf

https://help.sumologic.com/07Sumo-Logic-Apps/22Security_and_Threat_Detection/F5_-_BIG-IP_LTM/01Collect_Logs_for_the_F5_-_BIG-

I have created the source in SumoLogic, and configured the F5. I can see SumoLogic is getting the logs, but for some reason not all dashboards are working properly. For several of the F5 dashboards, I am getting "Unable to parse input as json". I have tried modifying the collector by enabling "multiline processing", but nothing changed.

Any suggestions are much appreciated.

Thank you
