• Inodes — The percentage of inodes currently in use.
An inode is a data structure that holds information about files in a Linux file system. There is an inode
for each file, and a file is uniquely identified by the file system on which it resides and its inode number
on that system.
Requirements
— The Red Hat Network Monitoring Daemon (
rhnmd
) must be running on the
monitored system to execute this probe.

D.5.5. Linux::Interface Traffic
The Linux::Interface Traffic probe measures the amount of traffic into and out of the specified interface
(such as eth0) and collects the following metrics:
• Input Rate — The traffic in bytes per second going into the specified interface.
• Output Rate — The traffic in bytes per second going out of the specified interface.
