This one introduces a new config precentage attribute for additionally shaking the next check around based on the check interval. Default: 0% – no breaking change.

0% (checks/s)

before

20%

after

This should be a good Xmas gift of the one of our customers with high check latencies.

I've talked with @lippserd about that, we will re-iterate on that for a later version. 2.12 only waits for the JSON-RPC bug and is feature frozen.

@lippserd Shall we default this one to 20, not to 0 so by default we de-spike the checks, but the user can disable that if they've got a grapher w/ slots?

Btw. this would automatically run much less e.g. ping checks to the same address concurrently.

We should stick with the 0% default. Documentation is missing.

@lippserd I.e. you plan to include this?
