Hello guys！  
This is my telegraf configuration

My influxdb contains information about the collection of computer resources, where is it collected from, my telegraf is not configured for collection. And the memory information collected is not quite the same as the parameters I’m actually using.

This is my actual memory usage  
Mem: 8061404k total, 7551008k used, 510396k free, 161240k buffers  
Use about 7 gigabytes.

The query from influxdb looks like this

758751232  
That translates to about 700MB.  
What’s it about?
