It looks like I am now able to model devices.
This ran once then failed.
I was able to model a device with a blank password in zenhub daemon and "zenoss" as the password in zen modeler daemon.
Zenhub deamon will not start with zenoss as the password. Niether will zeneventd or zenactiond. However clearing the password box allows these daemons to start.
I am still not gathering performance data. Error log shows 2013-07-19 16:13:51,767 WARNING relstorage.adapters.mysql: Unable to connect: (1045, "Access denied for user 'zenoss'@'localhost' (using password: YES)")
