cpu iowait
Reports the percentage of time the system was waiting for I/O to complete
or to handle an interrupt.
cpu system
Shows how much of the CPU time was spent on system-level tasks.
cpu usage
Reports how much of the managed system's CPU set was spent in the
user, system, and nice states. This is the default view.
load average
Reports the 1, 5, and 15 minute load averages.
mem buffers
Shows how much of the managed system's memory is allocated to
system-wide memory buffers.
mem shared
Reports the amount of memory shared among applications.
mem used
Reports the percentage of memory in use for all activities, for example,
code, buffers, and shared memory.
swap info
Reports the amount of swap space available and the amount of swap
space in use.

The Sorted menu specifies how to sort the detail graphs. The options are as follows:
Displays those managed systems with the greatest data first.
ascending
by hostname
Displays the managed systems by
regardless of the data.
descending
Displays those managed systems with the least data first.
•
The System Details link opens the Nagios Service Status Details for All Hosts window.
•
Selecting the Get Fresh Data button in the top right-hand corner updates the graph with any
available new data.
NOTES:
•
The detail graphs for a system show the graphs for a specified metric on all Nagios hosts.
The detail graphs for a Nagios host show metrics for that Nagios host.
•
Certain graphs might appear empty because the data graphed is an insignificant percentage
of the total.
Graphs for cpu system and cpu iowait, in particular, are calculated as a percentage
of the total available CPU time (including cpu idle), not just the CPU time used. Although
cpu system
as a percentage of CPU time used can typically be as high as 20% or 30%,
cpu system
as a percentage of total CPU (including cpu idle) can often be 1% or less.
Likewise, in some cases, mem buffers and mem shared might also appear empty.
