Instead of having a collection every <interval> (10 seconds by default), it will get a collection between the <interval+collection_jitter> *for each plugin*. So a same instance of telegraf could gather bcache metrics at, say, 11 seconds, and the procstat one at 13 seconds.

The precision of the jitter is the nanosecond though [0][1]

I'll try to gather a snapshot of a graph with "before/after" the change on a compute node and all instances' telegraf.
Changing just on a compute node hasn't been conclusive.
