Processor speed: The clock frequency of the
system's processor. Proc Speed (GHz) CPU Capacity
The number of physical (not logical) processor
cores that are active on the system. Core Count
The headroom percentage indicates how much
the demand for the CPU could grow before
violating the system's CPU utilization limits.
This metric is capped at 3100% to avoid
dividing by zero or other small numbers.
CPU Headroom (%)
Indicates if the system has hyper-threading
enabled (true), or disabled (false). Hyper-Threading
The percentage of valid CPU samples during
the selected interval. Data points can be invalid
if:
• The system is down and data cannot be
collected from it.
•
The CMS is down and cannot collect any
data.
• Data was collected, but a user marked the
data as invalid.
% CPU Valid
Details about the processor hardware, as
provided by the operating system. For
example, Intel Itanium 2 processor. Processor CPU Manufacturer Details
Annualized percent growth of the average CPU
utlization over the past 3 to 13 months.
•
A Not Enough Data (NED) symbol appears
if there is not more than 3 months of data
collected on this system.
•
An infinity symbol (∞) appears if the growth
rate was greater than 1000% or less than
–100%.
CPU Growth Rate (%) CPU Trends
The number of days until the trend in the 15
minute sustained CPU load reaches 70% of the
CPU capacity.
•
A Not Enough Data (NED) symbol appears
if there is not more than 3 months of data
collected on this system.
• An infinity symbol (∞) appears if the
computed trend line was level or declining,
or the CPU load will not reach 70% in the
next 2000 days.
Days to 70% CPU
The number of days until the trend in the 15
minute sustained CPU load reaches 80% of the
CPU capacity.
•
A Not Enough Data (NED) symbol appears
if there is not more than 3 months of data
collected on this system.
•
An infinity symbol (∞) appears if the
computed trend line was level or declining,
or the CPU load will not reach 80% in the
next 2000 days.
