Hi,
I got distributed polling /dispatcher service basically running.
But looks like I got some issues.
Looks like it’s running, but when checking via “./validate.php” or "./validate.php -g distributedpoller
" on the poller, it outputs the following:
bash-4.2$ ./validate.php

Do I need mamcached on the poller. Asking because I set up a redis server on another host to connect to.
Also is it correct that the validate shows " [INFO] Detected Dispatcher Service". I got the dispatcher service running.

I am asking because my services I monitor keep flapping up/down
