[0] 1. [Question] Would a person want to use both agent and agentless monitoring on the same system? When? [Answer] 
As we learned during the polling questions, 62% of the respondents already use a combination of agents and agentless monitoring. Using both methods on the same system can enhance your monitoring experience and offer a redundant monitoring solution for mission critical servers. What you use will depend on how you want to manage performance and cost. If you want to collect many metrics at very granular time intervals, an agent may be best. If your IT policies prevent you from installing agents on some types of servers, you can still monitor them using SiteScope. And, collecting performance counters with SiteScope is done in a lightweight manner.
