I currently work for CBS. I'm in a battle between the systems Architect and myself. The battle is what monitoring tool to use. I want to bring ZenOSS in. he wants to bring in Ganglia! We are going to be monitoring I think close to 20 web cluster and other servers which come to about 5K servers/switches/routers/...etc. He says ganglia is better suited for us because ganglia is always broadcasting its info to the central server which means no delays in grabbing important info. Where as polling for snmp based on a certain time interval he says is inefficient! Can you think of any argument on why we should use ZenoSS? He says zope/xmlrpc is bloated which it is but not a deal breaker. His only major concern is that ZenOSS wont be able to scale!
Ganglia was designed for a single purpose, cluster monitoring. Using it as a general NMS is next to useless. It only supports *nix variants, some poorly. You can't monitor routers/switches with it. If this is all your management cares about, use Ganglia. It was expressly designed for you. Zenoss is a general NMS, and therefore is infinitely more flexible. You get full-fledged event management with it, including customizable alert notifications. You can collect data passively (without polling) from SNMP traps, syslogs, Windows event logs or XML-RPC. You can actively collect absolutely anything, but SNMP, SSH , WMI, TCP and ping are included out of the box. You also get auto discovery and inventory management. All of this without even requiring an agent on the device to be monitored. Zenoss will scale, but it will definitely take more resources to do so than Ganglia. For the scale of your deployment, you'll need one big (quad proc, 4GB RAM) box for your central Zenoss (MySQL/ZODB) and one powerful (dual proc, 2GB RAM) box per cluster. This isn't a de-facto requirement, but should work well based on my experiences. In the end, Ganglia and Zenoss can't and shouldn't be compared to each other. -- Chet Luther [EMAIL PROTECTED] _______________________________________________ zenoss-users mailing list [email protected] http://lists.zenoss.org/mailman/listinfo/zenoss-users
