Php information doesn’t return anything about couchbase module except for version

Hello,
I've recently installed couchbase php extension (2.0.5) and can't see any runtime variables with php -i, except for version and the fact it parsed additional ini file (couchbase.ini)
I am using centos 6.6 , libcouchbase 2.4.8 and libevent-last-2.0.21 (remi), php 5.5.23

php -m shows the module is loaded as well as phpinfo() or php -i, however no other details I see for the module settings.

I don't mind it behaving that way as long as I know all settings (variables) I apply are really applied

Please advise

(I seen something similar in internet, but there was no reply to the problem)

Thanks!
Alex
