In Datadog, what does the term system.disk.used refer to?

The term system.disk.used in Datadog refers to the amount of disk space currently in use. This metric measures how much of the total disk capacity is occupied by data at a given moment. Understanding this metric is crucial for monitoring disk usage trends over time and ensuring that disk space does not become a bottleneck for application performance.

By tracking the amount of disk space used, users can make informed decisions about capacity planning, optimizing storage resources, and addressing potential storage issues before they impact system performance. This metric is a vital component of system monitoring, assisting in maintaining the health and efficiency of disk operations within an infrastructure.

Other options pertain to various aspects of disk monitoring but are distinctly different from what system.disk.used measures. For instance, total disk capacity available refers to the overall storage limit, the percentage of disk space utilized indicates how much of the disk is being used relative to its total capacity, and the frequency of disk usage checks discusses how often monitoring occurs, none of which directly reflect the specific measure of space currently utilized.
