Software Metering

Last Updated: May 30, 2018 12:37AM IST
Sam360 can automatically meter software usage of all applications running across the network. This includes
  • Windows® applications
  • Web applications (Internal and external)
  • Legacy client/server applications accessed through Terminal Emulator applications
  • Virtualised applications presented through Citrix, Microsoft RDS (Terminal Services, RemoteApp etc.) & Microsoft App-V

E.g. Microsoft Office Application Usage Details


E.g. Microsoft Office Daily Usage Details


E.g. Microsoft Office Streaming Server Details

Sam360 offers both an agent based and an agent free method for metering software.
 

Agent Based Software Metering


The easiest way to enable software usage data collection is to deploy the Sam360 software metering agent to each device to be metered. This includes user desktops & notebooks, but also RDS servers (Citrix, Microsoft RemoteApp etc.) and VDI VM images. The agent loads in to each user's Windows® session and tracks…
  • Which applications (and products) are executed
  • Which application has user focus
  • Execution context information (e.g. Active domain for web browsers, active server for terminal emulators)
  • When applications start and finish
  • To which terminal applications are streamed (RDS Servers, VDI VMs)
 

Agent Free Software Metering

In some situations, it may not be practical or feasible to deploy an agent to collect software usage data. Sam360 offers a 'lighter weight' alternative that collects high level application usage data without the need for an agent. The Sam360 Management Point can be configured to take periodic remote snapshots of software usage data from RDS servers. A snapshot includes the following information for the moment the snapshot is created…
  • Which applications (and products) are executing
  • To which terminals applications are streamed for all current users

Snapshots do not record which application has user focus or exactly how long an application was used for. However, if they are created periodically (e.g. every 15 minutes) for an extended period (e.g. 1 month) they can collect over 99% of all applications that are executed by a particular user, on a particular server from a particular terminal/thin client. Often this information is sufficient in determining software licensing requirements.
 
Clients can choose either method or adopt a hybrid approach using a combination of both agent based and agent free metering. The following table outlines some of the major difference between both options.
 
  Agent Based Agent Free
Deployment
Environment Supported All Windows® devices from Windows XP SP3 & Windows Server 2003 onwards All Windows® servers from Windows Server 2008 onwards. Terminal Services/Remote Desktop Services must be enabled.
Software Sam360 Agent must be installed on each device to be metered A single Sam360 Management Point can remotely meter up to 2,000 RDS servers
Proxy If all internet traffic is routed through a proxy, each user must be allowed to access Sam360 servers without manual authentication Only the Management Point user requires access through the proxy to Sam360 servers
Local Firewall No change required Management Point needs access to WMI and SMB service on RDS servers. (UDP & TCP Ports 135, 139 & 445)
Data Collected
Applications Used 100% ~99%
Thin client name Yes Yes
Focussed Application Yes No
Context Information e.g. Active Browser Domain Yes No
Resource Footprint
Process 1 instance of s3agent.exe per active Windows® session. 1 instance of s3mp.exe per Management Point.
Process Memory s3Agent.exe has private working set of <4MB s3mp.exe has private working set of ~ 15MB Can go to 50MB while snapshotting up to 1000 servers.
Process CPU s3agent.exe very rarely registers over 0% in Task Manager. s3mp.exe idles at <1% CPU. CPU usage increases slightly during snapshot activity
Network Bandwidth ~40B/s per user ~5B/s per user
Transmitting Sockets Peak: 10 per 1,000 active Windows® Sessions Peak: 5 per 1,000 RDS servers
Open Sockets Peak: 300 per 1,000 active Windows® Sessions Peak: 10 per 1,000 RDS servers
 

Notes

1 Software metering is not required to determine the most recent user of a device. A normal Sam360 inventory scan detects & records all current device users. Daily inventory scanning can create a basic view of users of a device.
