System requirements for the Continuous Optimization Agent

The following hardware requirements and supported operating systems apply to the Continuous Optimization Agent. The Gateway Server supports all versions of the Continuous Optimization Agent that are earlier than or the same as the Gateway Server version.

Hardware requirements

The following table describes the hardware requirements for the Continuous Optimization Agent.

Operating systemDisk space required for
Agent installationDaily data collectionHistorical data

/etc file system

Windows, UNIX, and Linux300 MB

1 or 2 GB based on the number of processes, file systems, disks, and network interfaces in the system.

Depends on the size and the configuration of your system. For information about estimating the disk size for storing historical data, see Estimating the disk space on the Agent system for historical data.

(For UNIX and Linux)

2 MB

Note: Make sure that you have the execute (x) permission to the /etc directory.

For Linux systems, ensure that the installation directory is on a standard Linux file system such as ext3 or a Global File System (GFS) for high availability deployments (Active/Passive servers). Installation on a CIFS share mounted as a file system is not supported. You can use CIFS share only for the shared repository.

Supported operating systems

The following operating systems are supported for direct installation of the Continuous Optimization Agent:

Patch requirements for the operating system

Patch forPackage nameDetails

For Solaris 11:

  • SUNWpool
  • SUNWpoold
  • SUNWpoolr

To verify that these packages are installed, run the following command:

> pkginfo | grep SUNWpool

Supported platforms for a Docker host

To install the Agent by using the Docker container, the following Linux systems are supported on a Docker host:

  • Red Hat Enterprise Linux
  • Ubuntu
  • CentOS

File systems

  • Create the agent history and daily data collection repositories on a local file system.
  • To use remote data repositories on a UNIX network file system, make sure that the rpc.lockd and rpc.statd NFS lock manager daemons run on both the client and server computers.
