What types of thresholds can be set for databases in Dynatrace?

The statement regarding the types of thresholds that can be set for databases in Dynatrace accurately highlights various critical performance indicators. When monitoring databases, it is essential to track response time degradations, increases in failure rates, and failed database connections, as these metrics directly affect the performance and reliability of database operations.

Response time degradations can signal underlying issues, such as inefficient queries or resource bottlenecks. Monitoring increases in failure rates is crucial for identifying potential failures before they escalate into more significant problems, which could impact application performance and user experience. Lastly, tracking failed database connections helps administrators understand connectivity issues that might arise in their infrastructure, allowing for proactive measures to maintain system stability.

The other options do not encompass the comprehensive performance metrics typically monitored in Dynatrace for databases. For example, while change in user sessions and traffic volume is significant for overall application monitoring, it is less specific to database health. Resource allocation and storage limits may be important operational metrics but do not directly represent the performance thresholds relevant to immediate database issues. Focusing solely on response time degradations ignores other critical factors that can affect database performance. Therefore, option B encompasses the most relevant and essential thresholds for effectively managing database performance in Dynatrace.
