The vtpStats() function (I think that's what it's called) that shows MIG Writes and Read is a good indicator it's building hits - so that'll be a good | |||
thing to check if you aren't seeing hits in data to see if that shows anything (we can estimate the event builder hit rate on the VTP based on the number | |||
of MIG writes & reads per second). Let me know if you'd like me to try in debug something (particularly if you have it in a weird state: if you can leave | |||
it in that state I can try to login to check). | |||
