How to check whether nginx's gzip_static is effective

Question

I have compiled the gzip static module and configured it as follows

gzip  on;
gzip_static on;
gzip_http_version 1.0;
gzip_disable "MSIE [1-6]\.";
gzip_vary on;

gzip_comp_level 2;
gzip_proxied any;
gzip_types text/plain text/html text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript;

Then the gz package of js and css is also placed in the same directory as the source file, but I can't see access to gz in the log. Is there any way to confirm that nginx does use the gz package?
