System requirements for Cloud Probe
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 6.x (64-bit)
- CentOS 7.x (64-bit)
- Oracle Linux 7.0
- Ubuntu 14.04.xx LTS
- 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 system | Expected volume of traffic | CPU consumption | RAM 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)
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:
