This alert presents the percentage of used file descriptors for CockroachDB.
If you receive this, it means that there is high file descriptor utilization against the soft-limit.

This alert is raised in a warning state when the metric exceeds 80%.

In Unix and Unix-like computer operating systems, a file descriptor (FD, less frequently
fildes) is a unique identifier (handle) for a file or other input/output resource, such as a
pipe or network socket.

File descriptors typically have non-negative integer values, with negative values being
reserved to indicate “no value” or error conditions.1
