Managing Your License

edit

When you initially install Watcher, a 30 day trial license is installed that allows access to all features. At the end of the trial period, you can purchase a subscription to keep using the full functionality of Watcher along with Shield and Marvel.

When your license expires, your watches will still be triggered but no actions will be performed. You will not be able to get existing watches or add new ones, but you can still delete watches.

Updating Your License

edit

You can update your license at runtime without shutting down your nodes. License updates take effect immediately. The license is provided as a JSON file that you install with the license API.

The endpoint for the license API changed to _license in Elasticsearch 2.0. If you are still running Elasticsearch 1.x, use the _licenses endpoint to update your license. For more information about managing licenses on 1.x, see the Shield 1.3 Reference.

To update your license:

  1. Send a request to the license API and specify the file that contains your new license:

    curl -XPUT 'http://<host>:<port>/_license' -d @license.json

    Where:

    • <host> is the hostname of the Elasticsearch node (localhost if executing locally)
    • <port> is the http port (defaults to 9200)
    • license.json is the license JSON file

    If Shield is enabled, you need cluster admin privileges to install the license.

  2. If the license you are installing does not support all of the features available with your previous license, you will be notified in the response. To complete the license installation, you must resubmit the license update request and set the acknowledge parameter to true to indicate that you are aware of the changes.

    curl -XPUT 'http://<host>:<port>/_license?acknowledge=true' -d @license.json

Viewing the Installed License

edit

You can also use the license API to retrieve the currently installed license:

curl -XGET -u admin:password 'http://<host>:<port>/_license'
{
  "license" : {
    "status" : "active",
    "uid" : "0a98411f-73f4-4c67-954c-724874ed5488",
    "type" : "trial",
    "issue_date" : "2015-10-13T18:18:20.709Z",
    "issue_date_in_millis" : 1444760300709,
    "expiry_date" : "2015-11-12T18:18:20.709Z",
    "expiry_date_in_millis" : 1447352300709,
    "max_nodes" : 1000,
    "issued_to" : "elasticsearch",
    "issuer" : "elasticsearch"
  }
}

If Shield is enabled, you need cluster admin privileges to retrieve the license.

License Expiration

edit

License expiration should never be a surprise. Warnings are displayed on startup and written to the Elasticsearch log starting 30 days from the expiration date. These error messages tell you when the license expires and what features will be disabled if you fail to update it:

# License will expire on [Thursday, November 12, 2015]. If you have a new license, please update it.
# Otherwise, please reach out to your support contact.
#
# Commercial plugins operate with reduced functionality on license expiration:
# - marvel
#  - The agent will stop collecting cluster and indices metrics
# - shield
#  - Cluster health, cluster stats and indices stats operations are blocked
#  - All data operations (read and write) continue to work
# - 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
