Hello everybody.

I'm testing the Beats dashboards in Kibana and I'm getting a strange behavior with the topbeat's cpu usage graph because always returns zero value.

I've created a new visualization with the same metrics using the max aggregation and I get the same results. I don't get why , because the records have non zero value all the time. Could you help me understanding what's going on?

Example:

"cpu": {  
"user": 405432,  
" **user\_p": 0.0405,**  
"nice": 1117,  
"system": 244784,  
**"system\_p": 0.0264,**  
"idle": 10914762,  
"iowait": 82614,  
"irq": 0,  
"softirq": 453,  
"steal": 0  
},

Thanks in advance,

Ignacio.
