Zenoss Core
Monitoring is performed using the Windows Remote Management (WinRM) and Windows Remote Shell (WinRS) to collect Windows Management Instrumentation (WMI) and Perfmon data.
The back end of the Zenoss 5 performance data system is a robust Big Data architecture featuring Redis, Hadoop HBase and OpenTSDB. Utilizing Big Data allows Zenoss users to deploy inexpensive commodity hardware to scale horizontally, rather than utilizing expensive SSD storage.
