Which types of events are tracked by Dynatrace for performance monitoring?

The tracking of machine reboots and new code deployments by Dynatrace is crucial for performance monitoring because these events provide significant insights into the system's operational status and behavior. When a machine reboots, it may affect application availability and performance. Tracking reboots helps in identifying patterns or frequent outages that could indicate deeper underlying issues.

Similarly, new code deployments are vital since they can significantly influence application performance. Detected performance degradation following a new deployment can prompt immediate investigation into potential bugs or performance issues introduced by that deployment. This proactive monitoring allows teams to address and rectify performance problems before they affect end-users.

Other options, while relevant to performance monitoring, do not encompass the breadth of visibility that machine reboots and code deployments offer. For example, user login events might provide insights into user behavior but are not primarily used for monitoring performance. Network latency events and database transaction failures are critical for diagnosing specific issues but do not provide the foundational context about the health of the infrastructure or the deployment lifecycle as comprehensively as tracking machine reboots and new code deployments does.
