Monitoring is also improved in Zenoss Core 4 by way of something known as enhanced, ZenPing suppression. Strimling explained that essentially, Zenoss utilizes NMAP for ICMP packet generation which is much more versatile than the normal ping command.
“We can use half-syn connections to verify if something is up or down without requiring an ICMP packet,” Strimling said. “Finally, Zenoss can do application specific port checks without needing to run netstat on the target.”
