Disk space requirements for the BigFix client (BigFix scenario)

Edit online

Ensure that computers on which you are installing BigFix clients meet the minimal hardware and disk space requirements.

Important: The following disk space requirements do not include the size of files that are downloaded to the endpoint by some of the fixlets. For example, the fixlet Download IBM License Metric Tool, downloads the application installer to the specified endpoint. Thus, more space is required on the targeted endpoint.

To check whether a fixlet downloads any files to the targeted endpoint, log in to the BigFix console, and check the value in the Download Size column for the particular fixlet. Then, ensure that enough disk space is available on the endpoint.

Table 1. Disk space requirements for clients installed on UNIX
Operating system Directory Space required Comments
UNIX /opt/BESClient 80 MB Client installation directory.
/var/opt/BESClient 250 MB Client data directory. This directory contains all scan results.
600 MB The additional space is required if the VM Manager Tool is installed on the endpoint.
/opt/tivoli/cit 50 MB Scanner installation directory.
/opt/tivoli/cit/cache_data 100 MB on average Scanner cache files.

The required disk space depends on the number of files, directories, and subdirectories to be scanned. It can be estimated by multiplying the number of files to be scanned by 60 bytes.
/etc/cit < 1 MB Scanner configuration files.
/tmp 100 MB on average Scanner temporary files.

The required disk space depends on the scanner options that are used (for example, sorting) as well as the number of files, directories, and subdirectories to be scanned. It can be estimated by multiplying the number of files to be scanned by 100 bytes.
/usr/ibm/tivoli/common/CIT 10 MB Scanner log files.
Table 2. Disk space requirements for clients installed on Windows
Operating system Directory Space required Comments
Windows C:\Program Files (x86)\BigFix Enterprise\BES Client 150 MB Client installation and data directory. This directory contains all scan results.
700 MB The additional space is required if the VM Manager Tool is installed on the endpoint.
C:\Program Files\tivoli\cit 20 MB Scanner installation directory.
C:\Program Files\tivoli\cit\cache_data 50 MB on average Scanner cache files.

The required disk space depends on the number of files, directories, and subdirectories to be scanned. It can be estimated by multiplying the number of files to be scanned by 60 bytes.
%WINDIR% < 1 MB Scanner configuration files.
%TMP% or %TEMP% 100 MB on average Scanner temporary files.

The required disk space depends on the scanner options that are used (for example, sorting) as well as the number of files, directories, and subdirectories to be scanned. It can be estimated by multiplying the number of files to be scanned by 100 bytes.
C:\Program Files\tivoli\ibm\tivoli\common\CIT\logs 10 MB Scanner log files.
