System requirements for the Capacity Agent

This topic provides hardware requirements and supported operating systems for the Capacity Agent.

Hardware requirements

The following table describes the hardware requirements for the Capacity Agent.

Operating systemDisk space required for
Agent installationDaily data collectionHistorical data
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 Linux systems, the installation directory of each product component must be on a standard Linux filesystem such as ext3 or a Global File System (GFS) for high availability deployments (Active/Passive servers). Installation on a CIFS share mounted as a filesystem is not supported. You can use CIFS share only for the shared repository.

Supported operating systems

The following operating systems are supported for the Capacity Agent installation:

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

The following Linux systems are supported for running the Agent on a Docker host:

  • Red Hat Enterprise Linux
  • Ubuntu
  • CentOS

Other requirements

  • On UNIX and Linux systems, ensure that at least 2 MB of free space is reserved for the /etc file system on all the managed systems, and you have the execute (x) permission for the /etc directory.
  • Create the agent history and daily data collection repositories on a local file system.
  • If you want to use remote data repositories on a UNIX network file system, ensure that the rpc.lockd and rpc.statd NFS lock manager daemons run on both the client and server computers. 
  • Ensure that semaphores and shared memory segments are configured on the managed systems where Capacity Agents are installed. For information about configuring the  shared memory and semaphores, see Configuring the shared memory and semaphores.

Virus scan settings

To avoid unnecessary CPU cycle consumption, BMC strongly recommends configuring the virus scan software to exclude scanning *.lox and *.udr files and any of the following directories:

  • best1_collect_home\bgs\monitor\log
  • best1_collect_home\history
  • %BEST1_HOME%\history

The path of the best1_collect_home directory can be C:\Program Files\BMC Software\Patrol3\BEST1\<product_version> or similar.
