[dpdk-dev] [PATCH v4] doc: guidelines for library statistics

The suggested solution with only one single flag per library prevents implementing statistics with varying granularity for different purposes. E.g. a library could have one set of statistics counters for ordinary SNMP purposes, and another set of statistics counters for debugging/optimization purposes.

 

Multiple flags per library should be possible. A hierarchy of flags per library is probably not required.

 

And since the compile time flag CONFIG_RTE_<LIBRARY_NAME>[_<STATS_COLLECTION_NAME>]_STATS_COLLECT already tells the application if the statistics are present or not, the application should simply use this flag to determine if statistics are accessible or not.
