Registry clj protocol

This protocol is used to extend the CollectorRegistry. This is done to ultimately ensure thread safety and to dynamically register collections. The prometheus java client currently only lets you register new collections, existing collections will throw an IllegalArgumentException

nc-lock clj

(nc-lock t)

Retrieve the nameCollectorsLock lock Object

nc-map clj

(nc-map t)

Retrieve the namesToCollectors map

register-dynamically clj

(register-dynamically t metric)

This will try and register a new collection if it doesn't or return an existing collection by doing the following:

• syncronize a lock on nameCollectorsLock
• get collection from namesToCollectors using :metric/name
• if collection exists return
• else register new collection and return
