Assure Host names are understood

Edited /etc/hosts file of both the master and collector. This was done, just in case the DNS of the hostname wont resolve. It is guarenteed to resolve if you enter the host names manually onto both collectors, and as long as the IPs set are static. 

[root@rborowicz-sandbox ~]# cat /etc/hosts

10.175.210.28   rborowicz-sandbox.zenoss.loc rborowicz-sandbox

[root@robo-remcol ~]# cat /etc/hosts

Add collector from GUI

This is the output from adding a remote collector via the root install method.

Interesting side notes

See that DAEMONS_TXT_ONLY exists, meaning that only the daemons in daemons.txt should be run. You do not want zope or zeo or other things running on a collector.

[root@robo-remcol etc]# cat DAEMONS_TXT_ONLY 
The presence of this file in $ZENHOME/etc/ tells the zenoss script that this
is a remote hub and/or collector.  In this situation the zenoss script does
not stop/start/restart/etc the traditional daemons that are controlled by the
zenoss script such as zenping, zenperfsnmp, etc.  Instead it controls only
those daemons listed in $ZENHOME/etc/daemons.txt.  Deamons installed as part
of a distributed hub or distributed collector are listed in daemons.txt.[root@robo-remcol etc]# cat daemons.txt 
robo-remcol_zenwinperf
robo-remcol_zenmailtx
robo-remcol_zenwebtx
robo-remcol_zentrap
robo-remcol_zenvmwareperf
robo-remcol_zeneventlog
robo-remcol_zenperfsnmp
robo-remcol_zenprocess
robo-remcol_zenstatus
robo-remcol_zenvmwareevents
robo-remcol_zenjmx
robo-remcol_zenping
robo-remcol_zenwin
robo-remcol_zencommand
robo-remcol_zenvmwaremodeler
robo-remcol_zenmodeler
robo-remcol_zensyslog
robo-remcol_zenrender

See that the same daemons are running. Note: zendisc is listed with a .conf file above, but is not a constantly running daemon.

Move a Couple devices over to it

In the GUI, find some device in the device list, drop down menu, Set Perf Monitor...
