Desktop Applications Test

This test discovers the applications executing on the cloud desktops and reports the availability and resource-usage of each of the desktop applications.

Target of the test : A Cloud Desktop Group

Agent deploying the test : A remote agent

Outputs of the test : One set of outputs for every distinct application executing on the cloud desktops.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.

Host

The nick name of the Cloud Desktop Group component for which this test is to be configured.

Port

Refers to the port at which the specified host listens to. By default, this is NULL.

Inside View Using

To obtain the 'inside view' of performance of the desktops - i.e., to measure the internal performance of the cloud-based virtual desktops - this test uses a light-weight eG VM Agent software deployed on each of the desktops. Accordingly, this parameter is by default set to eG VM Agent.

Report Powered OS

If this flag is set to Yes (which is the default setting), then the 'inside view' tests will report measures for even those desktops that do not have any users logged in currently. Such desktops will be identified by their name and not by the username_on_desktopname. On the other hand, if this flag is set to No, then this test will not report measures for those desktops to which no users are logged in currently.  

Report By User

This flag is set to Yes by default. The value of this flag cannot be changed. This implies that the cloud-based virtual desktops in environments will always be identified using the login name of the user. In other words, in cloud environments, this test will, by default, report measures for every username_on_desktopname.

Is Cloud VMs

Since this test runs for 'Cloud Desktop Group' component which is a cloud-hosted desktop group, this flag is set to Yes by default.

Exclude

Provide a comma-separated list of file patterns to be excluded from monitoring in the Exclude text box. This helps to filter out irrelevant file types that are not essential to the performance analysis of the desktop applications. For example *.vvf,*.pdf,*.jpeg,*.png,*.rbf,*.doc*.

DD Frequency

Refers to the frequency with which detailed diagnosis measures are to be generated for this test. For instance, if you set to 1:1, it means that detailed measures will be generated every time this test runs, and also every time the test detects a problem.

Detailed Diagnosis

To make diagnosis more efficient and accurate, the eG suite embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option.

The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

  • The eG manager license should allow the detailed diagnosis capability

  • Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Processes running

Indicates the number of instances of this application that is currently executing across all virtual desktops on the target host operating system.

Number

 

Physical CPU usage

Indicates the percentage of physical CPU resources utilized by this application across the guest VMs.

Percent

A very high value of this measure is a cause for concern, as it indicates excessive CPU usage by a single application. This in turn would cause other desktop applications to contend for limited physical resources, thus degrading the performance of those applications and that of the virtual server as a whole.

If this measure reports a value close to 100% for any application, then you can use the detailed diagnosis of this measure to identify which specific instance of that application is hogging CPU.

Memory usage

Indicates the amount of physical memory resources utilized by this application across the guest VMs.

MB

A very high value of this measure is a cause for concern, as it indicates excessive memory usage by a single application. This in turn would cause other desktop applications to contend for limited physical memory resources, thus degrading the performance of those applications and that of the virtual server as a whole.

If this measure reports a high for any application, then you can use the detailed diagnosis of this measure to identify which specific instance of that application is hogging memory.

CPU used

Indicates the physical CPU (in Mhz) used up by this application.

Mhz

 

I/O reads

Indicates the rate at which this application reads data from the virtual disk.

KB/Sec

Compare the value of these measures across applications to identify the I/O-intensive application.

I/O writes

Indicates the rate at which this application writes data to the virtual disk.

KB/Sec

I/O read operations

Indicates the rate at which this application performs read operations.

Operations/Sec

Compare the value of these measures across applications to identify the I/O-intensive application.

I/O write operations

Indicates the rate at which this application performs write operations.

Operations/Sec

Total I/O operations

Indicates the rate at which this application performs I/O operations.

Operations/Sec

Percent of memory usage

Indicates the percentage of memory used by this application.

Percent

A high value for this measure indicates that the application is consuming more memory. This is a cause for concern.

The detailed diagnosis of the Physical CPU usage and Memory usage measures list all the running instances of the given application, and reports the CPU and memory usage of each instance. From these insights, you can accurately isolate the instance that is consuming CPU and/or memory resources excessively.
