I am wondering if is there a way to see/get the message size ,for instance, per stream to calculate the Storage requirement for a bigger environment than my test-lab. And also to get the storage requriement per sending instance (linux,Windows,NetworkDevice).
Create widget with aggregation function on field gl2_accounted_message_size. Field gl2_accounted_message_size you can found in left menu icon X1 (Fields) after click all including reserved and type gl2 on search field.
