Hi,

I am currently using elasticsearch-5.4.0 and metricbeat-5.4.0 with Kibana. I created a basic elasticsearch setup on ubuntu 16.04 version. I created a watcher so that when CPU usage hits more than 75% i should get an alert with email. When i executed the watch api, i am getting output as given below.  
{  
"error" : {  
"root\_cause" : [  
{  
"type" : "general\_script\_exception",  
"reason" : "failed to compile script [ScriptException[compile error]; nested: IllegalArgumentException[unexpected token ['{'] was expecting one of [{, ';'}].];]"  
}  
],  
"type" : "general\_script\_exception",  
"reason" : "failed to compile script [ScriptException[compile error]; nested: IllegalArgumentException[unexpected token ['{'] was expecting one of [{, ';'}].];]"  
},  
"status" : 500  
}

Can anyone help me out with the situation.

Thanks!  
Kalyan

Can you post what you are trying to send to ES?

Hi,

Can anyone tell which API i need to execute to create watcher for alerting when CPU usage is more than 75%. I did basic elasticsearch-5.4.0 setup on ubuntu 16.04 and metricbeat and kibana as dashboard. I am using xpack for monitoring purpose.

Thanks  
Kalyan
