There are at least two ways: with or without pmlogconf.
If using pmlogconf (/etc/pcp/pmmgr/pmlogconf exists), create a new
file under $PCP_VAR_DIR/config/pmlogconf:

     ident nginx stuff
     probe nginx.active
           nginx

If not using pmlogconf (/etc/pcp/pmmgr/pmlogconf does not exist,
so /etc/pcp/pmmgr/pmlogger needs to have a "-c CONFIGFILE" part),
then add 

     log mandatory on default {
         nginx
     }

to the CONFIGFILE.  

In either case, then next time pmmgr reidentifies the target host (or
is restarted), pmlogconf may or may not run, and these metrics should
be amongst the ones polled.
