For dynamically determining packet sampling rates, a method including setting a packet sampling rate for one or more switch ports, collecting for an interval of time a plurality of statistics for the one or more switch ports, and adjusting the packet sampling rate in response to one or more of the plurality of statistics.

Dynamically determining packet sampling rates

A new file system is mounted to a mount point of an existing file system implemented in a computational system. A sentinel indicator is stored in the mount point. Prior to initiating an input/output (I/O) operation by a program, a determination is made by the program as to whether the sentinel indicator exists. In response to determining by the program that the sentinel indicator exists, the I/O operation is performed by the program. In certain alternative embodiments, in response to determining by the program that the sentinel indicator exists, the I/O operation is not performed by the program.
