-Library Statistics
-------------------
-
-Description
-~~~~~~~~~~~
-
-This document describes the guidelines for DPDK library-level statistics counter
-support. This includes guidelines for turning library statistics on and off and
-requirements for preventing ABI changes when implementing statistics.
-
-
-Mechanism to allow the application to turn library statistics on and off
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Each library that maintains statistics counters should provide a single build
-time flag that decides whether the statistics counter collection is enabled or
-not. This flag should be exposed as a variable within the DPDK configuration
-file. When this flag is set, all the counters supported by current library are
-collected for all the instances of every object type provided by the library.
-When this flag is cleared, none of the counters supported by the current library
-are collected for any instance of any object type provided by the library:
-
-.. code-block:: console
-
-   # DPDK file config/common_linux, config/common_freebsd, etc.
-   CONFIG_RTE_<LIBRARY_NAME>_STATS_COLLECT=y/n
-
-The default value for this DPDK configuration file variable (either "yes" or
-"no") is decided by each library.
-
-
-Prevention of ABI changes due to library statistics support
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The layout of data structures and prototype of functions that are part of the
-library API should not be affected by whether the collection of statistics
-counters is turned on or off for the current library. In practical terms, this
-means that space should always be allocated in the API data structures for
-statistics counters and the statistics related API functions are always built
-into the code, regardless of whether the statistics counter collection is turned
-on or off for the current library.
-
-When the collection of statistics counters for the current library is turned
-off, the counters retrieved through the statistics related API functions should
-have a default value of zero.
-
-
-Motivation to allow the application to turn library statistics on and off
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-It is highly recommended that each library provides statistics counters to allow
-an application to monitor the library-level run-time events. Typical counters
-are: number of packets received/dropped/transmitted, number of buffers
-allocated/freed, number of occurrences for specific events, etc.
-
-However, the resources consumed for library-level statistics counter collection
-have to be spent out of the application budget and the counters collected by
-some libraries might not be relevant to the current application. In order to
-avoid any unwanted waste of resources and/or performance impacts, the
-application should decide at build time whether the collection of library-level
-statistics counters should be turned on or off for each library individually.
-
-Library-level statistics counters can be relevant or not for specific
-applications:
-
-* For Application A, counters maintained by Library X are always relevant and
-  the application needs to use them to implement certain features, such as traffic
-  accounting, logging, application-level statistics, etc. In this case,
-  the application requires that collection of statistics counters for Library X is
-  always turned on.
-
-* For Application B, counters maintained by Library X are only useful during the
-  application debug stage and are not relevant once debug phase is over. In this
-  case, the application may decide to turn on the collection of Library X
-  statistics counters during the debug phase and at a later stage turn them off.
-
-* For Application C, counters maintained by Library X are not relevant at all.
-  It might be that the application maintains its own set of statistics counters
-  that monitor a different set of run-time events (e.g. number of connection
-  requests, number of active users, etc). It might also be that the application
-  uses multiple libraries (Library X, Library Y, etc) and it is interested in the
-  statistics counters of Library Y, but not in those of Library X. In this case,
-  the application may decide to turn the collection of statistics counters off for
-  Library X and on for Library Y.
-
-The statistics collection consumes a certain amount of CPU resources (cycles,
-cache bandwidth, memory bandwidth, etc) that depends on:
-
-* Number of libraries used by the current application that have statistics
-  counters collection turned on.
-
-* Number of statistics counters maintained by each library per object type
-  instance (e.g. per port, table, pipeline, thread, etc).
-
-* Number of instances created for each object type supported by each library.
-
-* Complexity of the statistics logic collection for each counter: when only
-  some occurrences of a specific event are valid, additional logic is typically
-  needed to decide whether the current occurrence of the event should be counted
-  or not. For example, in the event of packet reception, when only TCP packets
-  with destination port within a certain range should be recorded, conditional
-  branches are usually required. When processing a burst of packets that have been
-  validated for header integrity, counting the number of bits set in a bitmask
-  might be needed.

 Checking Compilation

-directory of the DPDK repo::

-  devtools/test-build.sh x86_64-native-linux-gcc+next+shared
-
-The script usage is::

-   test-build.sh [-h] [-jX] [-s] [config1 [config2] ...]]
-
-Where:
-
-* ``-h``: help, usage.
-* ``-jX``: use X parallel jobs in "make".
-* ``-s``: short test with only first config and without examples/doc.
-* ``config``: default config name plus config switches delimited with a ``+`` sign.
-
-Examples of configs are::
