Some questions about Zenoss 4.2.5 vs Zenoss 6.x
I've been tasked with investigating the work involved in moving from our current Zenoss 4.2.5 to Zenoss 6.x and am struggling to find information on some aspects of it.
This move is partly being prompted by the fact that Zenoss 4 is based on Centos 6.x and the powers that be would like us to move to Centos 7 for various reasons.
On the offchance… Has anyone ever tried getting Zenoss 4 to run ok on Centos 7? Or is this out of the question..
I've got a test 6 box stood up on my local machine using the master ova for playing around with and testing zenpacks.
So far in my experimentation with 6.x I noticed the following underlying components have changed… any others I've not spotted yet?
RRDTool has been replaced by OpenTSDB
mysql has been replaced by mariadb
Is there any sort of nice handy Zenoss document detailing the changes from 4 to 6?
I've got several custom zenpacks that use rrdtool, which now don't install as rrdtool is no longer present, is there any guidance out there of what this has been replaced with (metric façade?) and how to use it?
I've also got some custom portlets in Zenoss 4 and it looks like the portlet system has been rewritten – again is there any guidance as to how to add portlets into the new system?
Any thoughts appreciated.
(Our environments that we monitored are not large really (300 devices or less mostly) and so the forum wisdom I've read would suggest that staying with a stable version of Zenoss 4 would be wise, but unfortunately the Centos 6 issue may mean those making the decisions force a move…)
