Rob, This is of limited value to my business due to the GPL license -- so my company's lawyers tell me. I will be unable to take advantage of what looks to be a solid solution from what I can see of Zabbix. Are there any risks to Fuel (open source contamination) from this approach? I

Hi Bartosz, As for me - zabbix is bad practice to place on controller nodes when large installations will be monitoring, cause it can slow down disk IO on big db. If it happen - controllers can became unresponsible to other services on controllers. Zabbix guys recommended to use separate station

For small installs we still have to consider an option of roles combination, and placing Zabbix on controllers. Fuel disk allocation logic should be smart and has to allocate separate disk for it where possible. On Wednesday, November 26, 2014, Stanislaw Bogatkin sbogat...@mirantis.com wrote:

Im working on Zabbix implementation which include HA support. Zabbix server should be deployed on all controllers in HA mode. But zabbix-server will stay and user will be able to assign this role where he wants? If so there will be no limitations on roles allocation strategy that user can use

Bartosz, It is obviously possible to install zabbix on the master nodes and put it under pacemaker control. But it seems very strange for me to monitor something with software located on the nodes that you are monitoring. On Tue, Nov 25, 2014 at 4:21 PM, Bartosz Kupidura bkupid...@mirantis.com

Hello Vladimir, I agree. But in most cases, zabbix-server would be moved from failed node by pacemaker. Moreover some clients dont want to „waste” 3 additional servers only for monitoring. As i said, this is only first drop of zabbix HA. Later we can allow user to deploy zabbix-server not
