Citrix Server Test
This test generates statistics relating to a Citrix server.
Target of the test : Any Citrix server
Agent deploying the test : An internal agent
Outputs of the test : One set of results for every Citrix server being monitored

Measurement | Description | Measurement Unit | Interpretation |
---|---|---|---|
Application enumerations |
Represents the number of application enumerations per second |
Enums/Sec |
The Citrix Program Neighborhood allows a user to get a listing of all available applications published in the farm. This enumeration of resources takes place automatically every time the user launches the Citrix Program Neighborhood. This metric reflects the rate of application enumerations. An unusually high number of numerations can slow down a Citrix server. |
Application resolutions |
Represents the number of application resolutions per second |
Resolutions/sec |
When the user clicks the link to a published application, the link is resolved to an application. This metric reflects the workload on the server in terms of application accesses. The rate of application resolutions depends on the number of users connecting to the farm, duration for which the average user stays logged on, and the number of published applications. If the rate of application resolutions is excessively high, consider creating multiple zones in the farm to reduce the load on the data collector. |
Datastore connection failure: |
Indicates how long the Virtual Apps server was disconnected from the datastore. |
Mins |
The data store of the Virtual Apps server hosts centralized configuration data for a server farm. The data store is critical for central administration of the server farm. Hence, any loss of communication between a Virtual Apps servers and its data store can result in inconsistencies in the configuration data. A high value of this measure is hence a cause for concern as it indicates that the Virtual Apps server has been disconnected from the datastore for a long time. |
Datastore reads |
The rate of data read from the IMA data store |
KBytes/Sec |
This metric reports the workload on the data store. Since it is a central repository for a farm, slowdown of the data store can impact the performance of the farm. Data store traffic is usually high during server startup. |
Datastore writes |
The rate of data written into the IMA data store |
KBytes/Sec |
This metric reports the workload on the data store. Since it is a central repository for a farm, slowdown of the data store can impact the performance of the farm. |
Dynamic store reads |
The rate of data read from the IMA Dynamic store |
KBytes/Sec |
The dynamic store maintains information that changes frequently such as current sessions, disconnected sessions, server load, etc. This metric denotes the read rate of data from the dynamic store. |
Dynamic store writes |
The rate of data written into the IMA Dynamic store |
KBytes/Sec |
The dynamic store maintains information that changes frequently such as current sessions, disconnected sessions, server load, etc. This metric denotes the rate at which data is written to the dynamic store. |
LH cache reads |
The rate of data read from the IMA Local Host Cache |
KBytes/Sec |
Each server has a subset of the data store called the local host cache. The local host cache performs two functions:
The larger the cache, greater the hits to the cache and fewer data store accesses. Comparing the read rate from the local host cache and the data store, the administrator can assess the cache efficiency. |
LH cache writes |
The rate of data written into the IMA Local Host Cache written/sec |
KBytes/Sec |
|
Zone elections |
Indicates the number of zone elections that have occurred |
Number |
Zones in a Citrix farm serve two purposes - (a) to collect data from member servers in a hierarchical structure; (b) efficiently distribute changes to all servers in the farm. The first server in a farm is the data collector of the farm by default. Elections within a zone are used to determine the data collector for the zone. Frequent zone elections in a zone can result in increased network traffic. |
Zone elections won |
Indicates the number of times a Citrix server has won a zone election |
Number |
