run an action every 30 seconds

[michalkraus]

Hello,
I would like my Nginx server to run every 30 seconds a service job. This
job will just send a message to another server that the nginx is running
and OK. Does anybody know how to do it?
I have just one idea - to write a module that will send the OK message
to another server. Then cron will run each 1 minute (unfortunately 30
seconds is not possible) a script that will send a request to the
module.

Thanks in advance for your ideas,
Michal
