What might indicate that a virtual machine was terminated improperly?

Monitoring unavailability is a clear indicator that a virtual machine may have been terminated improperly. When a virtual machine is functioning normally, it continuously sends data to monitoring tools, allowing users to track performance metrics, application health, and resource usage. If a virtual machine is terminated without going through the proper shutdown sequence, it may not be able to send its final metrics or status updates to monitoring tools, resulting in gaps or complete unavailability in the monitoring data.

The consequence of this unavailability provides crucial information. It suggests that there has been an unexpected issue with the virtual machine, whether due to improper shutdown, crashes, or other operational failures. This can signal to administrators that further investigation is required to determine the root cause, whether it's a configuration error, system resource issue, or unforeseen application fault.

In contrast, increased application speed, successful queries, and real-time data tracking reflect positive states of the system and do not directly suggest any abnormalities related to the operation of a virtual machine. These indicators might imply optimal performance but can be misleading when assessing the overall health and proper functioning of virtual machine environments. Thus, monitoring unavailability stands out as a reliable sign of potential issues stemming from improper termination.
