Watches dont execute

When I start Elasticsearch I get the message:

 Commercial plugins operate with reduced functionality on license expiration:
# - watcher
#  - PUT / GET watch APIs are disabled, DELETE watch API continues to work
#  - Watches execute and write to the history
#  - The actions of the watches don't execute

Why won't my actions execute? Do I need to pay?

Hey,

please read the lines above this paragraph carefully, this shows if your license is expired or when it will expire.

Watcher is a commercial addon to Elasticsearch, but it comes with a trial one month license. You can read more about it at the bottom of the download page.
