I followed the instructions on the web which link is [https://www.elastic.co/guide/en/watcher/current/watch-cluster-status.html](https://www.elastic.co/guide/en/watcher/current/watch-cluster-status.html).  
But I found the head plugin will be abnormal when I add a cluster health watcher. The browser and Structured Query on the web can no be used.

elasticsearch version: 2.4

Hey,

Watcher is not able to change any other plugin, including the site plugin. Can you describe more exactly, what is failing and also add a screenshot.

thank you for your reply!

I can use the head plugin normally before add a health watcher.

the watcher is:  
curl -XPUT [http://localhost:9200/\_watcher/watch/cluster\_health\_watch](http://localhost:9200/_watcher/watch/cluster_health_watch) -d '{  
"trigger": {  
"schedule": { "interval" : "10s" }  
},  
"input": {  
"http": {  
"request": {  
"host": "localhost",  
"port": 9200,  
"path": "/\_cluster/health"  
}  
}  
}  
}'

I can not use head plugin normally after add the healty watcher!

Hey,

did a quick check and could not reproduce. Adding your watch and opening the browser worked on 2.4.2. Can you use the chrome inspector/console to see if any loading fails?
