X-Pack Watches not initializing properly

Elastic Stack Elasticsearch
1

I have ES 5.4.1 installed and the X-Pack plugin is also installed. I am trying to use Watcher, but it is not setting itself up properly.

When I call 'POST _xpack/watcher/_start' I get this error in the log files:

[2017-06-20T07:15:04,815][WARN ][r.suppressed ] path: /_xpack/watcher/_start, params: {}

And when I send a 'GET .watches' request, I get back:

{
"error": {
"root_cause": [
{
"type": "index_not_found_exception",
"reason": "no such index",
"index_uuid": "na",
"resource.type": "index_or_alias",
"resource.id": ".watches",
"index": ".watches"
}
],
"type": "index_not_found_exception",
"reason": "no such index",
"index_uuid": "na",
"resource.type": "index_or_alias",
"resource.id": ".watches",
"index": ".watches"
},
"status": 404
}

So it looks like the .watches index is not being setup. Is there something explicit that I have to do in order to get the .watches index setup properly?

Hey,

How many nodes do you have? Have you installed x-pack on all nodes? Did you restart after installation?

Can you show the output of

GET _cat/plugins?v
GET _cat/nodes?v

We have: 3 Master/Data nodes and 2 Client nodes...
X-Pack is on all nodes ...
Restart was done after upgrade from 5.3 ... as well as being restarted recently after setting 'xpack.watcher.enabled: true' in the elasticsearch.yml file.

Here is the output you requested ...

GET _cat/plugins?v

FE2    x-pack    5.4.1
Node3  x-pack    5.4.1
FE1    x-pack    5.4.1

Node2  x-pack    5.4.1

Hey,

can you share the settings or the cluster state? It looks as if Node1 still has watcher disabled, given the endpoint cannot be found.

Ran 'GET _nodes' and found that Node1 didn't have watcher enabled like you suspected. Turned out the elasticsearch.yml configuration file wasn't updated properly. I updated the configuration and restarted and it looks like the .watches index was created.

Watcher stats now returns this:

{
  "watcher_state": "started",
  "watch_count": 4,
  "execution_thread_pool": {
    "queue_size": 0,
    "max_size": 56
  },
  "manually_stopped": false
}

Thanks for the help!
