The BMC Real End User Experience Monitoring Cloud Probe component connects to a running Real User Collector. The following system requirements are necessary to install and use the Cloud Probe: 

Operating system requirements

The Cloud Probe supports the following operating systems:

  • Red Hat Enterprise Linux 5.8 and later (64-bit) 
  • Red Hat Enterprise Linux 6.x (64-bit) (Basic Server or Minimal installations)
  • Red Hat Enterprise Linux 7.x
  • CentOS 5.8 and later (64-bit) 
  • CentOS 6.x (64-bit)
  • CentOS 7.x (64-bit)
  • Ubuntu 14.04.xx LTS
  • Ubuntu 15.10
  • Ubuntu 16.04.xx LTS
  • Windows Server 2008 R2
  • Windows Server 2012
  • Windows Server 2012 R2 
  • Windows Server 2016

Hardware requirements

Each server where the Cloud Probe is installed requires the following minimum hardware:

  • 2 GB RAM
  • 2 CPUs

Note

In the table below, see the approximate percentage of CPU and RAM capacity used by the Cloud Probe on the tenant computer (tested with 2 virtual CPUs and 4Gb RAM on Linux, and with 4 virtual CPUs and 16Gb RAM on Windows).

Cloud Probe CPU and RAM usage

Operating systemExpected volume of trafficCPU consumptionRAM consumption
Red Hat Enterprise Linux 6.3~1000 hits/sec~5%~10%
Microsoft Windows 2008 Server (R2)~800 hits/sec~5%~10%

Network requirements

The Cloud Probe must connect to an instance of the Real User Collector using HTTPS. You can  change the default port (443), if necessary.

For a list of the supported cipher suites, see Cipher suites support for SSL/TLS decryption.

Network Time Protocol (NTP) synchronization

Warning

The data handled by application monitoring components, including all server components and agents, is time sensitive. If the time between components is not synchronized, you might see incorrect or partial data, or you might not see any data.

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.

Software requirements

Linux

 For Linux operating systems, you must have the following libraries installed:

Note

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

  • Zlib
  • Libicu
  • Libpcap
  • Openssl
  • Pcre
  • Libcurl
  • Network Security Services (NSS)
  • ifconfig

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

Windows 

Before installing the Cloud Probe on a Windows operating system, you must download and install the WinPcap tool installed on the Cloud Probe machine.

SSL/TLS and cipher suite support for HTTPS traffic

If the Cloud Probe component monitors HTTPS traffic on the network, it supports the following SSL and TLS protocols versions:

  • SSL version: 3.0
  • TLS versions: 1.0, 1.1, and 1.2

 The following table lists the ciphers suites supported by the Cloud Probe:

    regarding the approximate percentage of CPU and RAM capacity used by the Cloud Probe.

    if I have 4000 hits per second last 5 mins this is mean the agent will consume 25% percentage form CPU and Memory 

    1. Hi Mohamed,

      Yes, the Cloud Probe uses approximately the proportional amount of CPU and memory capacity. If the machine has the same specifications as the one documented above—on Linux, 2 virtual CPUs and 4Gb RAM—and the hit rate is about 4000 hits per second, then the agent uses approximately 20% CPU and 40% RAM.

      Alternatively, you can use a machine with four times the resources—on Linux, 8 virtual CPUs and 16Gb RAM)—so that the Cloud Probe supports four times the hit rate (4 x 1000 hit/sec) with 5% CPU and 10% RAM.

      Hope this helps!
