- Cache hit on 'ddl' key 'agent/nrpe'
-
-Additional Information
-----------------------
-
-MCollective has an internal Cache used to speed up operations like parsing of DDL files. The cache is also usable from the agents and other plugins you write.
-
-Each entry in the cache has an associated TTL or maximum life time, once the maximum time on an item is reached it is considered expired.
-
-This log line indicates that a request for a cache entry was made, the entry had not yet expired and so the cached data is being returned.
-
-It does not indicate a problem, it's just a debugging aid
