Plugin updates
==============

To update the plugins, stop the Centreon Engine on **all pollers**.

Update the plugins on **all pollers**::

   # yum update centreon-plugins*

Restart the Centreon Engine on **all pollers**.

Then check that you do not have new errors while executing new plugins.

.. note::
    It is your choice whether to install all the plugins on every poller, or just the
    required plugins. Keep in mind that you may encounter errors if you migrate a monitored host
    to a poller that happens to be missing
    the necessary plugins. If you update the plugins on the Centreon central server, be
    sure also to update them on each poller.
