Hi,Can anybody explain what is the difference between Infrastructure Data Collector (InfrastructureDC) and Web Service Data Collector (WS DataCollector)?Do we just need either one of them to collect data or both of them need to be running? Do they depends on each other? If my InfrastructureDC is not running, will the WS Data Collector still collect data as normal? Please advise and clarify my confusion between the two.Thanks a lot.

InfrastructureDC is used to collect information from webMethods products like IS, Broker TN etc.
Web Service Data Collector (WS DataCollector) is used to collect information from non-webMethods product i.e. some other applications like siebel etc(You receive this information through web service hence web service collector
