Esxtop allows monitoring and collection of data for all system resources: CPU, memory, disk and network. When used interactively, this data can be viewed on different types of screens; one each for CPU statistics, memory statistics, network statistics and disk adapter statistics. In addition to the disk adapter statistics in earlier versions, starting with ESX3.5, disk statistics at the device and VM level are also available. Starting with ESX 4.0, esxtop has an interrupt statistics screen. In the batch mode, data can be redirected to a file for offline uses.
