I am seeing the refresh interval of 5 seconds instead of 1 second that I thought was the default. However, I want to change it to 1 second - I was wondering if there is a way to do it without bringing any of the nodes down. I have a cluster with 4 nodes and 1 index. Here is the status from 1 of the 4 nodes:

os: {  
refresh\_interval: 5000  
cpu: {  
vendor: "Intel"  
model: "Xeon"  
mhz: 2266  
total\_cores: 2  
total\_sockets: 2  
cores\_per\_socket: 16  
cache\_size: "8kb"  
cache\_size\_in\_bytes: 8192  
}  
mem: {  
total: "3.9gb"  
total\_in\_bytes: 4194304000  
}  
swap: {  
total: "1.9gb"  
total\_in\_bytes: 2097434624  
}  
}

Thanks - I appreciate your help!

-cheers,
