Pollerlog page with remote pollers

Hi. I recently configured 1 mysql+rrdserver(rrdcached) and 2 remote poller servers

I noticed OBSERVIUM_URI/pollerlog/ shows nothing since rrdserver doesn't poll.

Poller server #1 makes [poller-wrapper_2_0.rrd, poller-wrapper.rrd, poller-wrapper_count.rrd]

Poller server #2 makes [poller-wrapper_2_1.rrd, poller-wrapper.rrd, poller-wrapper_count.rrd]

It seems observium_home/html/pages/pollerlog.inc.php file's

$rrd_file = $config['rrd_dir'].'/poller-wrapper.rrd';

is causing problem, since rrdserver doesn't have poller-wrapper.rrd files at local. I think I should either

1. Somehow integrate rrd files and copy it to rrdserver every minute or so (rsync, etc)

2. Find a way to make poller wrapper python processes from the poller servers to integrate and copy to my rrdserver.

I'm not sure if poller_wrapper_2_0.rrd and poller-wrapper.rrd are both needed too.
