The wizard prompts for the following, all of which should have already

been conﬁgured:

1. LVM volume group name (for example, vgclog)

2. Logical volume in the volume group (for example,

/dev/vgclog/lvol1)

3. The ﬁlesystem’s mount point (for example, /clog)

4. The ﬁlesystem’s mount options (for example, –o rw,largefiles).

The mount options are used verbatim in the Service package control

script’s FS_MOUNT_OPT[0] ﬁeld. Note that the mount options must

agree with the ﬁlesystem you created on the logical volume. For

example, if the ﬁlesystem was created with largeﬁles support, the

largeﬁles mount option should be speciﬁed. Since consolidated logs

tend to be large, it is recommended to conﬁgure VxFS ﬁlesystems

with the largeﬁles option.

5. The ﬁlesystem type (for example, VxFS)

6. The package IP address. This should also be a registered DNS name

so the log forwarding is easy to conﬁgure on client systems.

7. The package subnet. Use netstat -i to determine the proper

subnet.

Next, the wizard prompts for the client’s transport.

You can choose to have the clients forward logs to this

consolidation server via the UDP protocol or the TCP protocol

(recommended).

Do you want to use the TCP protocol? (y/n) [y]:

Note that selecting TCP does not necessarily preclude the use of UDP

forwarded log messages by clients. Whether the log consolidator allows

TCP log messages exclusively, depends on whether the system is

consolidating its own local syslog ﬁle. See below for details.

When answering Yes to TCP, you must select a free TCP port. This port

must be free on all cluster members. See the section “Conﬁguring a Log

Forwarding Client Using clog_wizard” on page 203 using the clog_wizard

for details on choosing a TCP port.

Next the wizard prompts for which local logs should be consolidated:
