The VMStat data source is used to monitor various performance aspects of a *nix host. When the data source starts a process is initiated that runs the vmstat program, and the output from that process is monitored.
Every data source requires a Name, which can be any description. The Poll seconds setting determines how often the vmstat process will report data back to Scada-LTS. The Output scale can be set to automatically adjust byte values to different scales, including bytes, k, KB, m, and MB.
