4.2.2 Estimating the disk capacity required for EADS clients

This subsection explains how to estimate the disk capacity required for EADS clients.

Organization of this subsection

(1) Estimating the total size of log files per EADS client

The following shows the formula for estimating the total size of log files per EADS client.

Total size of log files per EADS client (megabytes) =

a + 70 megabytes

Explanation of the variables

a: Size of message log files output by an EADS client

For details about log files managed by EADS clients, see 8.4.1 Types of log files.

(a) Size of message log files output by an EADS client

The following shows the formula for estimating the size of a message log file output by an EADS client.

Size of message log files output by an EADS client (megabytes) =

size of a message log file (bytes) [Figure] 1,0242

[Figure] number of message log files

Size of a message log file (bytes):

eads.client.logger.message.filesize parameter value in the client properties

Number of message log files:

eads.client.logger.message.filenum parameter value in the client properties

Round up the value to the next full megabyte because the value of the eads.client.logger.message.filesize parameter in the client properties is specified in bytes.
