Prerequisites
If you have all the following software and hardware elements, you can move directly to installing an On-premise monitor.
Required
Details
Cautions
Hardware Min, Med, or Max
The availability of functions depends upon hardware capabilities.
Network Access
Outbound port 443 must be open. Alternatively, an HTTP proxy can be used.
Only HTTP proxy (with optional password authentication) can be used. HTTPS and SOCKS proxies are not supported.
Software
Debian 8, Red Hat Enterprise Linux 7, or CentOS 7 operating system with all the required packages, Software Requirements
Ensure that you follow the steps in Software Requirements during the OS installation.
Access rights
The OPMS installer must be run under the root user.
Running the installer using sudo is not supported.
Hardware Requirements
The server hardware limits the type and number of agents that the OPMS can run. These hardware requirements also apply to virtual machine installations.

IPv6 Support
Not Applicable
Yes, native or tunneled
Yes, native. Tunnels are not recommended.
Minimum hardware requirements
A minimal OPMS host can run all agents except the RBM.
Medium hardware requirements
A moderately sized OPMS host can run up to 5 RBMs concurrently.
Optimum hardware requirements
An optimal OPMS host can run at least five RBMs concurrently.
Bare metal hardware is recommended for optimum performance, but a virtual machine can be used too. For information about compatibility with Debian 8 or RedHat/Oracle Linux/CentOS 7.x, refer to your virtualization solution provider.
Software Requirements
If the XFS filesystem is used, the d_type (directory entry type) support must be enabled (XFS filesystem parameter ftype) to comply with docker storage driver compatibility requirements.
If the d_type is not supported, the installation stops. For more information, see overlayfs driver.
You can check the compatibility using the
xfs_info /var
command. A result ftype=1, indicates a supported file system. A result ftype=0, indicates an unsupported file system and you must recreate the compatible file system.
OPMS requires one of the following operating systems:
  • Debian 8
  • Red Hat Enterprise Linux 7.x
  • Oracle Linux 7.x
  • CentOS 7.x
Install the Operating System
To use the OPMS installer graphical interface, the graphical desktop environment must be present. You can also use a text console for installing the OPMS.
Follow these steps:
  1. Obtain the installation image for your Linux distribution.
  2. Run the OS installer on the host.
  3. Specify the hostname. Do not use the suggested default localhost.
  4. Specify your network domain in the <domain>.<TLD> format. Do not use the suggested default local domain.
  5. Specify the partition layout.
    1. Debian
      The default layout is recommended.
    2. RHEL / CentOS / Oracle Linux
      Delete the /home partition and enlarge root partition to fill the unused space.
  6. Optionally, specify the HTTP Proxy for the download of installation packages. The proxy configuration that is entered in this step is used by the OPMS Installer and On-Premise Monitoring Stations (OPMS).
  7. Specify the following software selection:
    1. Debian
      1. SSH server
      2. Standard system utilities
      3. Graphical desktop environment (optional)
    2. RHEL / CentOS / Oracle Linux
      1. Server with GUI
  8. On Debian, ensure the package
    apt-transport-https
    is installed. Run the following command to install the package:
    apt-get install apt-transport-https
Post Installation Requirements
Perform the following post installations steps:
  1. Oracle Linux:
    Upgrade to the Unbreakable Enterprise Kernel Release 4 (UEKR4; see Release Notes for Unbreakable Enterprise Kernel Release 4). The second option is to install Docker Engine using official Docker documentation.
  2. RHEL:
    The installer needs access to the
    rhel-7-server-optional-rpms
    and
    rhel-7-server-extras-rpms
    repositories. The repositories are enabled automatically during install which
    requires a valid RHEL subscription
    . If you do not have a valid RHEL subscription, you must either provide access to the repositories or install all required packages manually. Contact your
    Linux administrator
    to get the list of required packages.
  3. Java Runtime Environment (JRE):
    Install Java Runtime Environment (JRE) version 8 (OpenJDK which is available in all supported Linux distributions can be used).
