As already mentioned, you can use the command line tool
Knifehttp://help.opscode.com/kb/chefbasics/knife to
enact an action on the chef-clients immediately. You can also setup the
chef-client to run from cron, or some other scheduler.
A third option would be to daemonize the chef-client. From the Chef
Wikihttp://wiki.opscode.com/display/chef/Chef+Client
:
"To run the chef-client as a persistent daemon, make your startup script for
the chef client execute something like:
$ chef-client -i 3600 -s 600
The -i option provides an Interval - it's how often the Chef client will
attempt to wake up and Converge this Node. The -s option is the Splay - a
random piece of time added to the interval, which helps avoid the thundering
herd problem."
By updating the policy on the server, when the chef client wakes up and
converges the node, it would reapply the policies from the Chef Server
enacting the change at the interval set for the persistent daemon.
If you use the chef-client
cookbookhttp://community.opscode.com/cookbooks/chef-client,
it automatically sets up the client to run as a daemon.
Unrelated note for your information: beyond use of this and the chef-dev
mailing list, and the IRC channel, as a Opscode Platform customer, you can
also direct questions to support@opscode.com or enter a support request
directly at help.opscode.com.

HI,
I saw the Opscode platform that it’s possible to mouse over the tab “run
list” at the point “Status” and see the complete run list of this node.
But
if I’m installing the server on my own, I didn’t get this feature. I can
click on it and nothing happened or mouse over. For what is this
button?!
It used to work on non-Platform webUI. I don't recall when it broke.
It did the same as you describe the Platform UI doing.
I'm pretty sure it was only informational. It had nothing to do with
actually running the client.

Soo my question is, is there a way to force an chef-client via the WEBUI?! It will be very nice, because if you have a necessary task and you have to do it now, you can’t login to every server and enter the command “chef-client” .
