Working with Usage

Chapter 15.

The Usage Server is an optional, separately-installed part of CloudPlatform that provides aggregated usage records which you can use to create billing integration for CloudPlatform. The Usage Server works by taking data from the events log and creating summary usage records that you can access using the listUsageRecords API call.

The usage records show the amount of resources, such as VM run time or template storage space, consumed by guest instances.

The Usage Server runs at least once per day. It can be configured to run multiple times per day.

15.1. Configuring the Usage Server

To configure the usage server:

1.Be sure the Usage Server has been installed. This requires extra steps beyond just installing the CloudPlatform software. See Installing the Usage Server (Optional) in the Advanced Installation Guide.

2.Log in to the CloudPlatform UI as administrator.

3.Click Global Settings.

4.In Search, type usage. Find the configuration parameter that controls the behavior you want to set. See the table below for a description of the available parameters.

5.In Actions, click the Edit icon.

6.Type the desired value and click the Save icon.

7.Restart the Management Server (as usual with any global configuration change) and also the Usage Server:

#service cloud-management restart

#service cloud-usage restart

The following table shows the global configuration settings that control the behavior of the Usage Server.

Parameter Name		Description

enable.usage.server		Whether the Usage Server is active.

usage.aggregation.timezone		Time zone of usage records. Set this if the usage
		records and daily job execution are in different
		time zones. For example, with the following
		settings, the usage job will run at PST 00:15 and
		generate usage records for the 24 hours from
		00:00:00 GMT to 23:59:59 GMT:

		usage.stats.job.exec.time = 00:15
		usage.execution.timezone = PST
		usage.aggregation.timezone = GMT

		Default: GMT

usage.execution.timezone		The time zone of usage.stats.job.exec.time.

4.2 specifications

Citrix Systems, a leading provider of virtualization solutions and cloud computing technologies, released version 4.2 of its popular software, Citrix XenApp, which was previously known as Presentation Server. This version marked a significant evolution in providing users with remote access to applications and desktops, emphasizing simplicity, performance, and security.

One of the standout features of Citrix XenApp 4.2 is its improved application streaming capabilities. This technology allows applications to be delivered to users in real-time, reducing the need for extensive local installations and enhancing the user experience. With application streaming, administrators can efficiently manage applications on a central server while ensuring that users have immediate access to the necessary tools.

Another highlight of this version is the enhanced security measures put in place to protect sensitive data. Citrix XenApp 4.2 includes support for SSL encryption, providing a secure communication channel for data transmitted between the server and clients. This is particularly crucial for businesses that need to comply with strict data protection regulations. Additionally, the integration of endpoint security features ensures that unauthorized access to applications is minimized.

Performance enhancements are also a critical focus in this release. Citrix optimized the delivery of applications over various network conditions, ensuring that users experience minimal latency regardless of their location. This was achieved through the incorporation of SmartAccess and SmartControl technologies, which allow administrators to set policies based on user roles, device types, and network conditions. This level of granularity enables organization-wide security without compromising on usability.

The user experience was further improved with a revamped interface, making it easier for end-users to access their applications and data. Simplified menus, clear navigation paths, and the ability to customize user settings contributed to a more efficient workflow, allowing users to focus on their tasks rather than struggling with the software.

Finally, Citrix XenApp 4.2 was designed to be highly scalable. Organizations of all sizes could deploy this solution to deliver applications efficiently, adapting to their specific needs as their user base grows or changes. This flexibility is crucial for businesses looking to future-proof their IT investments while maintaining optimal performance.

In summary, Citrix XenApp 4.2 stands out with its enhanced application streaming, robust security features, improved performance under varying conditions, user-friendly interface, and scalability, making it an ideal choice for organizations seeking to leverage virtualization for remote access to applications and desktops.
