The Real User Analyzer and Collector are components of the Real End User Experience Monitoring Software Edition. The following system requirements are necessary to install these components:

Operating system requirements

The Real End User Experience Monitoring Software Edition supports the following operating systems:

  • Red Hat Enterprise Linux 7.2 (64-bit)
  • CentOS 7.2 (64-bit)
  • Ubuntu Server 14.04 LTS (64-bit)

Some additional packages need to be present on the system (see "Requires packages" below) for the  Real User Analyzer and Collector components to work.

X Windows 

If you are installing these components using the graphical user interface, you must install the X Window system.

You should use your operating system's recommended method for installing the X Window system.

Required packages

Based on the operating system and version in use, you need the following libraries installed on your system:


Exact names of these libraries may vary depending on your operating system and version.

  • Crontab
  • Logrotate
  • Libaio
  • Perl (The Real User Analyzer uses a MySQL database that requires the Perl package.)

If you do not have these libraries installed, the installation will not run properly.

Network Time Protocol (NTP) synchronization

The data handled by application monitoring components, including all server components and agents, is time sensitive. If the time between components is not synchronized, data might not be displayed in the TrueSight console. Consult your operating system documentation to synchronize each component's internal clock with an NTP server on your network or on the Internet. Ensure that the clocks are regularly synchronized.

This applies to all Real End User Experience Monitoring Software Edition components and integrated App Visibility Monitoring components.

Hardware requirements

The Real User Analyzer and Collector hardware requirements are different for the Standard mode installation and the Demonstration (Demo) mode installation. The Demo mode is intended for proof of concept testing, and is only applicable for use cases that have a low volume traffic (up to 100 hits per minute). When you install the Analyzer and Collector components, the installation wizard includes the option to install the components in Demo mode. 

Each instance of the Real User Analyzer and Collector requires the following minimum resource requirements.


Standard mode

Real User Analyzer2 vCPU7 GB100 GB
Real User Collector2 vCPU7 GB100 GB

Demo mode

Real User Analyzer2 vCPU2.5 GB10 GB
Real User Collector2 vCPU2.5 GB10 GB

After an Analyzer or Collector is installed, your system must have an additional 1 GB of memory available for the operating system.


  • While recent hypervisor products are able to manage resource allocation dynamically, it is important not to overallocate processor and memory resources for the Analyzer and Collector. It is also important to remember that the hypervisor itself has resource requirements. Therefore, if a given host has 32 GB of memory, for example, and you deploy components which together have requirements approaching 32 GB, you can expect problems.
  • To optimize the performance of a component, you can increase or decrease resource allocations. If performance is unsatisfactory, for example, you can add extra processing power or memory.

Storage requirements

The Real User Analyzer storage is used for saving historical traffic data that you can access via the session browser (Analyzer). This data is stored "on board" the component.

The default disk configuration is 100 GB. To accommodate larger volumes of data, you can create a larger data disk (minimum 100 GB; maximum 570 GB) for each Real User Analyzer instance.

You can install the Analyzer in a Demonstration mode that only requires 10 GB.

Network requirements

The Real User Analyzer and Collector are interconnected to form a system. In addition, access to the interfaces of these components is achieved via the web. To avoid network-related performance issues, you must take certain configuration and infrastructure details into consideration when planning an installation. For example, deploy the Real User Analyzer and Collector in an optimized network in the cloud.

Supported LDAP servers

  • Microsoft Windows Server 2008 Active Directory
  • Microsoft Windows Server 2003 Active Directory
  • OpenLDAP (slapd)
