Zabbix provides monitoring metrics, among others network utilization, CPU load

@item Auto-discovery of servers and network devices and interfaces.
|

@item Low-level discovery, allows to automatically start monitoring new items, file systems or network interfaces among others.
|
||||
@item Distributed monitoring with centralized web administration.
|
||||
@item Native high performance agents.
|
||||
@item SLA, and ITIL KPI metrics on reporting.
