Process

fd.used.percent

The percentage of used file descriptors out of the maximum available. By default, this metric displays the average value for the defined scope. For example, if the scope is set to a group of machines, the metric value will be the average value for the whole group.

This metric should be monitored carefully, and used for alerts, as when a process reaches its file descriptor limit, the process will stop operating correctly, and potentially crash.

proc.count

The number of processes on host or container, excluding any processes that do not have .exe or command line parameters in the process table. These processes typically are kernel or system level, and are typically identified by square brackets (for example, [kthreadd]).

As some processes are excluded, the host level proc.count value will be lower than the value reported by the ps -ef command on the host.
