Possible to calculate CCU (Concurrent User) in each vHost?

Dear,
Is it possible to calculate CCU (concurrent user ) in each vHost using Nginx Modules VTS ?

Thanks for your help,
My sincere,

Hi.
Please see the issues/21.

Thanks so much for your help.
But I think the variable "Total Active Connection" is not CCU because it means how many sessions user interacting with web server. For example, If one user opens two sessions concurrently, the " Total active connection" is 2 but CCU is only 1, i think that.
If there have any mistaken in my options, would you like to give me the favors ?

You're right.
Do you maybe want to count the number of unique IP addresses per second?
The above feature has not been implemented.

Hi,
Thanks for your help. The module you write is very interesting. It helps me so much in my project to monitor Nginx server. The variable "Total active connections" sum up Request per seconds in each vHost, doesn't it ?
Best regards,
Tuan Kiet.

Yes, probably I think so if the keepalive is disabled(keepalive_timeout 0).
The variable ngx_stat_active(active) increased only one per a tcp connection and decreased when a tcp connection is closed.
FYI, See the ngx_http_stub_status_module and status variables in issue/35.
