I Noted following problen on installation of piwik:
The problem is that not all visit are registered by piwik system.
I can assert it because separately I´m registering in parallel on server site the all Post request that are received on server, with the all related url and IP address.
And it is confirmed by Google analytics that is registering the same as my Server site.
I needed to do it, with one other port, because the principal site run under https.
Somebody can give to me some tips where go to check ?
Many thanks in advance
