- merge StopChanMemProf with StopMemoryProfiling - remove fileMEM and stopMemProf from struct and constructors - add separate mutex for memory profiling, ensure thread safety - handle all significant errors - log error if StopMemoryProfiling fails during CoreS Shutdown - ignore errors if profiling inactive in Shutdown and deferred Stop - move validations inside V1 functions - return error if StartMemoryProfiling already started - return error if StopMemoryProfiling already stopped or never started - close profiling loop on error, not the cgr-engine - StopMemoryProfiling closes channel and profiling loop writes final profile - rename Path to DirPath for mandatory field error - rename memprof_nrfiles flag to memprof_maxfiles - increase default memprof_interval - consider MaxFiles <= 0 as unlimited - move memory profiling logic after starting services - use CoreService Start/StopMemoryProfiling in main - remove final memory profile block (created by deferred Stop) - convert MemProfiling to method on CoreService and rename to profileMemory - use Ticker for recurrent actions instead of Timer - compute mem_final.prof full path in StartMemoryProfiling - suffix profile files with current time instead of numbers - update dispatcher methods after changes - move MemoryPrf from utils to cores, rename to MemoryProfilingParams - add logs for starting/stopping profiling

==========
|
|
|
|
Groups most of functionality from services and components.
|
|
|
|
Customisable through the use of *json* :ref:`JSON configuration <configuration>` or command line arguments (higher prio).
|
|
|
|
Able to read the configuration from either a local directory of *.json* files with an unlimited number of subfolders (ordered alphabetically) or a list of http paths (separated by ";").
