What defines a resource problem in a monitored environment?

A resource problem in a monitored environment is defined by a shortage of a resource such as CPU or memory. This type of problem occurs when the available computing resources are insufficient to handle the workload effectively, leading to performance degradation. When there is a shortage of critical resources like CPU or memory, applications may struggle to execute tasks efficiently, resulting in slower response times, timeouts, or even application failures.

Identifying resource shortages is crucial for maintaining optimal system performance, as they can directly impact user experience and application reliability. Monitoring tools can help detect these shortages early, allowing teams to take proactive measures, such as scaling resources or optimizing applications, to prevent significant performance issues.

Other options highlight important aspects of application performance but do not specifically define a resource problem. For instance, excessive network usage can lead to bottlenecks and slow performance, but it does not necessarily indicate a shortage of computational resources. Similarly, high application error rates and unresponsive services can stem from multiple issues, including but not limited to resource shortages. However, they do not exclusively signify a resource problem as defined in this context.
