Timestamp issue

[Tekraj Chhetri]

While querying over HTTP API I observe strange timestamp issue. With the same time stamp different value for same metric and node.

[1583438931.781, '3567682048'] -- node_disk_read_bytes_total
[1583438946.781, '3567682048'] 
[1583438961.781, '3567682048'] 
[1583438976.781, '3567682048'] 
[1583438991.781, '3567682048'] 
[1583439006.781, '3567682048'] 
[1583439021.781, '3567682048'] 
[1583439036.781, '3567682048'] 
[1583439051.781, '3567682048'] 

The same metric but different value

[1583438931.781, '19287683072'] 
[1583438946.781, '19287683072'] 
[1583438961.781, '19287683072'] 
[1583438976.781, '19287683072'] 
[1583438991.781, '19287683072'] 
[1583439006.781, '19287683072'] 
[1583439021.781, '19287683072'] 
[1583439036.781, '19287683072'] 
[1583439051.781, '19287683072'] 

And due to this when I am combining data i am getting something like shown below.

I resolved the issue it was due to different devices.
