Measures reported by CtxSDXXenCPUCorTest
The CtxSDXXenCPUTest test alerts administrators to abnormal CPU usage on an SDX appliance, which can typically be caused by one/more CPU cores being utilized excessively. The question now is, which CPU cores are contributing to the CPU contention. The CtxSDXXenCPUCorTest test answers this question by reporting the average CPU usage of each CPU core of an SDX appliance.
Outputs of the test : One set of results for each CPU core of the target NetScaler SDX.
| Measurement |
Description |
Measurement Unit |
Interpretation |
| Avg_cpu_usage |
Indicates the percent CPU usage of this CPU core. |
Percent |
A value close to 100% is a cause of concern, as it could indicate excessive usage of a core by one/more VPX instances on the target SDX appliance. If this condition is left unchecked, it can cause the overall performance of the SDX to significantly deteriorate and badly impact user-experience with the appliance.
Use the detailed diagnosis of this measure to know which instances are utilizing the core. Then, check the value of the Cpu_usage measure (reported by the CtxSDXInstancesTest test) for each of those instances to know which instance is hogging the CPU resources. |
