Troubleshooting Watcher

Dynamic mapping error when trying to add a watch

If you get the Dynamic Mapping is Disabled error when you try to add a watch, verify that the index mappings for the .watches index are available. You can do that by submitting the following request:

resp = client.indices.get_mapping(
    index=".watches",
)
print(resp)

response = client.indices.get_mapping(
  index: '.watches'
)
puts response

const response = await client.indices.getMapping({
  index: ".watches",
});
console.log(response);

GET .watches/_mapping

If the index mappings are missing, follow these steps to restore the correct mappings:

Stop the Elasticsearch node.
Add xpack.watcher.index.rest.direct_access : true to elasticsearch.yml.
Restart the Elasticsearch node.

Delete the .watches index:

resp = client.indices.delete(
    index=".watches",
)
print(resp)

response = client.indices.delete(
  index: '.watches'
)
puts response

const response = await client.indices.delete({
  index: ".watches",
});
console.log(response);

DELETE .watches

Disable direct access to the .watches index:
1. Stop the Elasticsearch node.
2. Remove xpack.watcher.index.rest.direct_access : true from elasticsearch.yml.
3. Restart the Elasticsearch node.

Unable to send email

edit

If you get an authentication error indicating that you need to continue the sign-in process from a web browser when Watcher attempts to send email, you need to configure Gmail to Allow Less Secure Apps to access your account.

If you have two-step verification enabled for your email account, you must generate and use an App Specific password to send email from Watcher. For more information, see:

Gmail: Sign in using App Passwords
Outlook.com: App passwords and two-step verification

Watcher not responsive

edit

Keep in mind that there’s no built-in validation of scripts that you add to a watch. Buggy or deliberately malicious scripts can negatively impact Watcher performance. For example, if you add multiple watches with buggy script conditions in a short period of time, Watcher might be temporarily unable to process watches until the bad watches time out.
