Measures reported by CtxCdLoadIdxTest

A server's load index may be the aggregate of:

  • Various computer performance counter based metrics, namely CPU, Memory and Disk Usage

  • Session Count

It is designed to indicate how suitable a XenApp Worker is to receive a new user session. It is the Citrix Cloud Delivery Controller's responsibility to calculate the load index based on the aggregate of the normalized load rule indexes generated by the various load rules. As only the Delivery Controller can determine the session load, a server's overall load index is calculated on the Delivery Controller and not the Virtual Delivery Agent.

Administrators can use the CtxCdLoadIdxTest test to periodically evaluate the load on the servers managed by a delivery group. This is imperative to ensure that load is uniformly balanced across the servers. In addition, in times of an overload, this test can help administrators accurately identify which server is overloaded and which resource is the constraint.

Outputs of the test : One set of results for every delivery group of each server OS type.

First-level descriptor: Server OS type

Second-level descriptor: Delivery Group

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Total Indicates the load evaluator index of this delivery group / machine. Percent By comparing the value of this measure across delivery groups / server OS machines, you can figure out whether or not load is uniformly balanced across all delivery groups / servers.

Use the detailed diagnosis of this measure to view the complete details of the machines in a delivery group and to view the CPU, disk, memory, and session load evaluator index of each machine.
Cpu Indicates the CPU load evaluator index of this delivery group / server OS machine. Percent A high value is indicative of excessive CPU usage by the delivery group / machine over time.
Memory Indicates the memory load evaluator index of this delivery group / server OS machine. Percent A high value is indicative of excessive memory usage by the delivery group / machine over time.
Disk Indicates the disk load evaluator index of this delivery group / server OS machine. Percent A high value is indicative of excessive disk usage by the delivery group / machine over time.
Session_count Indicates the session count load evaluator index of this delivery group / server OS machine. Percent A high value indicates that the delivery group / machine has been consistently handling many user sessions.
