# Checkmk update
This plugin mointors the update status of your CMK sites and your CMK appliance firmware. The plugin reads it's data once a day form the Checkmk download page (**https://download.checkmk.com/stable_downloads.json**).
THX to Baris Leenders for providing the data as JSON download and Martin Hirschvogel for supporting the development of this plugin (both from tribe29).
**NOTE**: before updating from the special agent version of this plugin, remove the old package completely (rules and package) please.
**NOTE**: to get the download URLs in the service details not replaced by CMK you need to disable `Escape HTML in service output` (_Setup_ > _Services_ > _Service monitoring rules_ > _Escape HTML in service output_) for the service `Checkmk Update`.
