Performance Monitoring
This topic comprises several aspects of internal performance of a device as a computing unit, i.e. "stand-alone" computer performance. The following computing facilities are covered here:
- central processing units (CPUs) -- see CPU Performance Monitoring;
- storage units (memory, hard disks, optical disks etc.) -- see Storage Monitoring;
- software running on the host (processes) -- see Process Monitoring.
Network performance and application/service monitoring (often regarded as a part of performance monitoring) are described separately.
Several device performance aspects, including gauges for CPU Load, Physical Memory Usage, Virtual Memory Usage can be displayed in real-time in a single window using IP Host Information widget.
Another stratum of performance monitoring -- concerning virtualization technologies -- should be mentioned here. Iotellect Network Manager monitors various metrics of VMware ESX server virtual machines performance. Being described in a separate dedicated section (see VMware Server Monitoring), virtualized infrastructure performance monitoring tools are also mentioned in the corresponding subsections below.
