Major improvements in the new release include:
- enhanced ZenPing suppression (essentially, the python code in ZenPing was rewritten to include better layer 3 link attributes)
- NMAP for ICMP packet generation
- a new auto-deploy script, making Zenoss Core 4 easier to install than past releases
I have found Zenoss to be a near perfect tool to help IT departments meet their monitoring needs in a more cost-effective manner. While my focus today is on Microsoft SCOM, Orchestrator and Service Manager, I encourage you to consider Zenoss as a long-term, thoroughly professional alternative.
