Table 16 Attributes available for use in analysis queries: CPU Tab (continued)
The “Hours One Core Utilized” attribute is the
number of continuous hours of that CPU load
that has been at or above a 1 core load. This
time interval always closes the analysis window
and its value is between 0 and 1000 hours.
Even when the analysis window is less than
1000 hours wide, the value can be as high as
1000.
The “Hours One Core Utilized” attribute is
useful in identifying systems where a thread or
process is in an infinite loop. System
performance improves when the process is
restarted. This is particularly true when the
infinite loop is in a VM and the performance
of many VMs are affected.
The value of this attribute is never greater than
the total amount of data collected on this
server. The number of hours might include short
runs of missing data and ends, if there is a
huge block of missing data.

Infinite Loop Detection
The “Hours Half Core Utilized” attribute is the
number of continuous hours of the CPU load
that is at or above a 1 core load. This time
interval always closes the analysis window and
its value is between 0 and 1000 hours. Even
when the analysis window is less than 1000
hours wide, its value can be as high as 1000.
The “Hours Half Core Utilized” attribute is
useful in identifying systems where a thread or
process is in an infinite loop. System
performance might improve if the process is
restarted. This is true when the infinite loop is
in a VM and the performance of many VMs
are affected.
The value of this attribute is never greater than
the total amount of data collected on the
particular server. The number of hours might
include short runs of missing data and ends, if
there is a huge block of missing data.

NOTE:
Peak, 15-minute sustained, 90th percentile, and average values are available as separate
attributes. See
