To configure data buffering:
1. Select Wizard - Step 4: Data Buffering.
2. Click the Enable Data Buffering checkbox. The Destination pull-down menu appears.
3. Select a location (either Local or Remote) for the data files from the Destination pull-down
menu. Additional pull-down menus and fields appear, based on which destination is selected.
4. When the destination is local, perform the following steps.
a. From the Mode pull-down menu, select Circular or Linear data buffering.
b. Type a file size in bytes into the File Size (Bytes) field. The file size should be greater than
zero.
5. When the destination is Remote, perform the following steps.
a. In the NFS File Path field, enter the pathname for the mount point of the directory where
the data buffer file is to be stored. For example, if the mount point pathname is
/var/adm/acslogs, enter
NOTE: The NFS server must already be configured with the mount point shared (exported), and the shared
directory from the NFS server must be mounted on the console server.
b. To cause a timestamp to be saved with the data in the data buffer file, select the Record the
timestamp in the data buffering file checkbox.
Definition
Local Destination only - Select Linear to write the data to sequential files or Circular
for non-sequential format.
In circular mode, data is written into the specified local data file until the upper limit
on the file size is reached; then the data is overwritten from the top of the file as
additional data comes in. Circular buffering requires the administrator to set up
processes to examine the data during the timeframe before the data is overwritten
by new data.
In linear mode, data is written into a sequence of files, and the files are not reused.
The administrator must make sure enough space is available for the expected
amount of data and take measures such as moving unneeded data files offline, to
ensure data does not outgrow the available space.
Local Destination only - Set a file size greater than zero. Make sure the file size
does not exceed the space available on the Flash memory. The recommended size
is 1024.
If selected, the system inserts a timestamp in the buffer.
Remote Destination only - Enter the path to the NFS server and the shared
directory where the data buffer file should be stored.
Select the options you wish to show in the menu of the buffer file.
/var/adm/acslogs in the field.
