When selecting an enterprise-level monitoring solution, one of the first decisions the IT department needs to make is whether to opt for an agent based, or agentless monitoring solution. The most important part of this decision making process is to understand what metrics you need to measure. Once you understand this, the process of finding the correct solution is quite simple. In a nutshell, agent-based solutions will give you access to much deeper and more granular metrics to aid in the fight against downtime while agentless solutions allow you to skip the step of deploying agents at the risk of less data and a less secure environment.
