The various versions of Unix vary quite a bit with something like kernel tuning. And even with HP-UX, the tools are evolving rather fast as HP moves toward dynamic reconfiguration. In general though, kernel tuning is reserved to root. Non-root users can be given access to root level commands via a tool like sudo. And prebuilt versions of sudo are available for HP-UX.

NAME
mtailrc - Configuration file for monkeytail
DESCRIPTION
A monkeytail configuration uses Apache-style syntax to declare "groups" of files to be tailed.
Best explained with an example:
<group testgroup>
prefix 'server2: '
sudo yes
<file>
filename /var/log/apache2/access.log
prefix 'server1: '
host server1.example.com
</file>
<file>
filename /var/log/apache2/access.log
host server2.example.com
sudo no
</file>
</group>
OPTIONS
All options can be either put inside a group or file block. Options inside a file block override those in the group block.
filename filename
filename defines the filename for this block.
host remote-host (optional)
host defines that this block's file is to be tailed on a remote server.
sudo yes|no|1|0
sudo is a boolean specifying whether this file should be tailed as root. This option is supported for both local and remote files
(in both cases you will potentially be prompted for your password).
prefix "string: "
prefix allows you to specify a short string that will be prepended to every line that is displayed for that given file.
FILES
