What is cxOsNbBufsFree?
This read-only integer displays the number of data buffers currently free (unused) in the system. Admins monitor this to catch buffer exhaustion, which can cause packet drops or processing failures under heavy load. For example, this value trending toward zero during peak traffic would warn an admin the system is close to running out of data buffers.
