Can this tool trace custom tracepoints ?

[baiwfg2]

Hi.

If we use this kind of tool to trace the path of long queries, I think we should add custom tracepoints to mongo source code to make it more useful, since we need to know many information such as how long the request stays in the queue, which node the request is sent to, how large the request size and response size is , and so on. For the moment, this tool cannot generate such information , right ?
