=== Troubleshooting a New Watcher Installation
|
|
|
|
If Watcher or Elasticsearch fail to start up properly after installation:
|
|
|
|
* Make sure you are running Elasticsearch 1.5 or later.
|
|
* Make sure the License plugin is installed on every node in the cluster.
|
|
* If you are using Shield, make sure you are running Shield 1.2.2 or later.
|
|
* Make sure Watcher is installed on every node in the cluster.
|
|
* Make sure all plugin versions are compatible with the Elasticsearch version.

=== Logstash Can't Connect to Elasticsearch after Installing Watcher
|
|
|
|
By default, Logstash uses the `node` protocol. When you use the node protocol, the Logstash
|
|
instance joins the Elasticsearch cluster. Because Watcher requires all instances in the cluster
|
|
to have the License plugin, Logstash cannot join the cluster unless it has the License plugin.
|
|
You can <<logstash-integration, install the Logstash License plugin>> or use the `transport` or
|
|
`http` protocol to ship data to Elasticsearch.

=== Dynamic Mapping Error When Trying to Add a Watch
|
|
|
|
If you get the error _Dynamic Mapping is Disabled_ 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:
|
|
|
|
[source,js]
|
|
--------------------------------------------------
|
|
GET .watches/_mapping
|
|
--------------------------------------------------
|
|
// AUTOSENSE
|
|
|
|
If the index mappings are missing, follow these steps to restore the correct mappings:
|
|
|
|
. Stop the node.
|
|
. Add the configuration setting `watcher.index.rest.direct_access : true` to `elasticsearch.yml`.
|
|
. Restart the node.
|
|
. Delete the `.watches` index:
|
|
+
|
|
[source,js]
|
|
--------------------------------------------------
|
|
DELETE .watches
|
|
--------------------------------------------------
|
|
+
|
|
. Disable direct access to the `.watches` index:
|
|
.. Stop the node.
|
|
.. Remove `watcher.index.rest.direct_access : true` from `elasticsearch.yml`.
|
|
.. Restart the node.

=== Unable to Send Email
|
|
|
|
If you get an authentication error that indicates 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
|
|
https://support.google.com/accounts/answer/6010255?hl=en[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:

=== Watcher Not Responsive
|
|
|
|
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.
