Remote testing - how do I see num of threads created?

I started doing a remote testing and I want to know the number of threads
created.
but I don't see it in the summerizer results.

basically I was doing a test with 500 users and I set a ramp up time of 2000
seconds - but from the summerizer results I saw that the all the 500 users
were created after about 5000 seconds.

Since I don't know if the problem comes from the JMeter limitation on my
machine or from my app I decided to do a distributed testing.

but than than when I run the distributed test I see all the time 'Active: 0
Started: 0 Finished: 0' - is there a way to get the number of threads
created info as well?
