Emitting custom metrics from hook functions

[hassy]

It's possible to add custom stats to Artillery's reports from hook functions as described here: #160 (comment)

The ability to do this is massively useful but the current code is only a proof-of-concept and needs to be rewritten.

• Logging histograms should be possible (already implemented)
• Logging counters should be possible
• It should be possible to merge custom metrics from several Artillery processes (when running on multiple cores / machines)
• It should be possible to annotate custom metrics with information for the graphical (HTML) reports

Hello @hassy , I've tried some of these custom hook functions to ensure pre-authentication occurs and log errors etc but I was wondering if it is possible to breakdown the status codes being returned for each uri and report them in the custom stats?
My flow does 5 gets currently, but I want visibility of where my failure occurs without scrolling through DEBUG mode trying to figure it out.
Could it just be as simple as anything other than 200 , add a counter for each particular get call for each particular code?

Not possible at the moment @kieranbop, custom counters haven't been implemented yet.

Broken link my dude.
I see everywhere the code for customStats but I am not able to figure out how to add big strings to it. (A json representing the "top" unix terminal command output).
