Which of the following monitor types cannot have SLOs created for them?

Process Monitors are specifically designed to track the performance and health of processes running on hosts. They provide insights into system-level metrics such as CPU usage, memory consumption, and the number of running processes. However, they do not inherently incorporate the concept of Service Level Objectives (SLOs), which are typically focused on the performance and reliability of services as perceived by end users rather than individual processes.

In contrast, Metric Monitors, APM Monitors, and Synthetic Monitors can all be associated with SLOs because they are aimed at measuring the performance of services and applications in ways that are directly relevant to user experience and satisfaction. For example, APM Monitors track application performance in the context of user transactions, while Synthetic Monitors simulate user interactions to measure response times and availability, both of which can establish SLOs for expected service levels.

Therefore, the correct answer identifies Process Monitors as the type that does not support the creation of Service Level Objectives in Datadog.
