I have some experience doing this sort of thing ;)

I would suggest using ssh and RSA authentication. You can generate blank
passphrases, so that you won't be prompted, then create a shell script from the
central machine that simply runs the script you created and redirects output to
the file you want to store centrally.

Step - by - Step

as the user who will run the script from the central server:
ssh-keygen (accept the blank passphrase)
then copy the contents of the file ~/.ssh/identity.pub to the remote machines in
the file ~/.ssh/authorized_keys in the home directory of the user who will be
running the script.

Test this by 'ssh'ing to the machine and logging in as the user who will run the
script: ssh -l remote_user remote_server

you should get logged in without getting prompted.

Next write a script that has one line for server you want to run the script on:
ssh -l remote_user remote_server command_to_execute >> central_log_file.date

Then try running the script. It may be necessary to get more detailed then
above, but this is the quick hack to get things working. If you need something
more specific, please let me know.
