Re: Zabbix feature review request

 

Based on the way the data-points appear to be collected, there is
definitely a point where monitoring the nodes will become too intense for a
node sharing roles (or even a single node) (I've personally overloaded most
monitoring systems in default configurations with ~200 nodes.) However a
single pane of glass to view all clusters is extremely important to the
operations teams. It is therefor necessary for us to be able to specify an
existing Zabbix server that may be deployed elsewhere, or even completely
outside the scope of fuel.

So to get down to it. we should be able to (1) install Zabbix as a role (2)
separately of the Zabbix role configure Zabbix agents on nodes inside a
cluster to point to a Zabbix node. (3) if a Zabbix role is defined in the
cluster assume that it should be used to configure (2) but allow it to be
replaced anyway.
