In TrueSight Capacity Optimization, data collection by means of agents and proxy agents is accomplished by installing a Gateway Server. The collected data is periodically transferred to the Gateway Server, where it is automatically processed into hourly intervals and saved in text files called vis files.
Agents are typically installed on the computer whose data is to be collected. In the case of Windows machines, it is also possible to collect data agentlessly using Windows Management Instrumentation (WMI). In this case, you designate a special Windows computer as a proxy agent node. You install an agent on this machine, and this single agent collects data from a list of Windows computers that you specify.
