I'm using Elasticsearch 2.3.5 ,Shield, marvel. I installed watcher and while verifying that Watcher is set up, using
> curl -XGET '[http://localhost:9200/\_watcher/stats?pretty](http://localhost:9200/_watcher/stats?pretty)'
I'm getting an error like:
> {
> "error": {
> "root\_cause": [
> {
> "type": "action\_not\_found\_transport\_exception",
> "reason": "No handler for action [cluster:monitor/watcher/stats]"
> }
> ],
> "type": "action\_not\_found\_transport\_exception",
> "reason": "No handler for action [cluster:monitor/watcher/stats]"
> },
> "status": 500
> }
Please help me out.
Thanks in advance

How did you install it?
What does `bin/plugin -l` or `_cat/plugins` show?

Doesn't show Watcher as installed on them all, did you restart node 3?

Restarted node 3 again. Now it's fine
