Tracing queries of MongoDB

Hi,
I am trying to trace the queries of MongoDB with an adaptation of the dbslower tool (bcc/dbslower_example.txt at master · iovisor/bcc · GitHub), but so far I was only able to trace parts of the queries that I executed, e.g. the database and collection name or the operation that I used and all of it spread across multiple traces. Has anyone here tried to trace the queries of MongoDB with bpf tools before? Any advice on how to get traces of complete queries with bpf would be appreciated.
