================================================================================ README for AppQoS December 2019 ================================================================================ CONTENTS ======== - Introduction - Requirements and Installation - Configuration - Usage - REST API - Usage Scenario - How To Generate self-signed SSL certificate - Legal Disclaimer INTRODUCTION ============ AppQoS is a proof-of-concept software created to demonstrate the use of Intel(R) RDT technologies (CAT, MBA) and Intel(R) SST technologies Base Frequency (BF), Core Power (CP) to improve QoS for applications via partitioning system resources. AppQoS allows to assign Apps to Pools with different resources. In current version each of the Pools (group of cores) has fixed amount of cache and memory bandwidth allocated. Thanks to Intel(R) SST BF and CP support, AppQoS allows the CPU to be deployed with an asymmetric core frequency configuration. Amount of resources allocated and cores frequency configuration could depend on Pool’s priority. Intel(R) RDT CAT and MBA configuration is done via "libpqos" library and Intel(R) SST BF and CP configuration via external "Intel pwr" library. AppQoS provides simple, local, REST API management interface secured with HTTPS and "Basic HTTP Auth". REST API management interface allows user to manage Apps and Pools. An App controlled by AppQoS could be a process, a container or a VNF. AppQoS is reference code written in Python. It is fully configurable and can be easily modified to suit other use cases and allow remote management. REQUIREMENTS AND INSTALLATION ============================= AppQoS requires minimum Linux kernel v4.20 (for Intel(R) RDT L3 CAT and MBA) however, for support of Intel(R) SST BF and CP Linux kernel v5.2 is required. AppQoS is a part of Intel(R) RDT Software Package, it is located in "appqos" directory. AppQoS requires Python v3.x and depends on the following Python modules and external components: - pqos (libqos Python wrapper) - flask - flask_httpauth - flask_restful - jsonschema - Intel pwr library (github.com, CommsPowerManagement) NOTE: All required dependencies are installed and AppQoS is executed in virtualenv when started via "make run" command. To install "pqos" module, clone "intel/intel-cmt-cat" repository or download source code from github (for more information about repository cloning or downloading source code, please see github.com help). git clone https://github.com/intel/intel-cmt-cat.git cd ./intel-cmt-cat or wget https://github.com/intel/intel-cmt-cat/archive/master.zip unzip ./master.zip cd ./intel-cmt-cat-master After getting the code, compile and install Intel(R) RDT Software Package (for more information, please see INSTALL file for Intel(R) Software Package). make sudo make install Intel(R) RDT CAT and MBA configuration is done via libpqos using MSR interface, for more information please see "Software Compatibility" section of README for Intel(R) RDT Software Package. For hardware requirements please see "Hardware Support" section of mentioned README file. To get and install "Intel pwr" library required to configure Intel(R) SST BF and CP please follow instructions at: https://github.com/intel/CommsPowerManagement CONFIGURATION ============= AppQoS supports Pools of Apps, each with defined cores, cache and memory bandwidth allocation. Each App describes a single app, with one or more PIDs. Cache Allocation, Memory Bandwidth Allocation (via CAT and MBA), Base Frequency, Core Power (via SST BF and CP) and affinity are configured by AppQoS on per core basis. NOTE: make sure that cores are isolated via "isolcpu=" kernel param. AppQoS config is stored in JSON format in file "./appqos.conf" for which JSON Schema file is available in "./schema" directory. Configuration file is "Read-Only", no runtime changes are saved. If there is no "Default" pool (with "id" equal to 0) defined in config file, AppQoS will dynamically create one on start-up. All unassigned cores will be assigned to "Default" pool, MBA will be configured to 100% and CAT CBM to all cache ways. EXAMPLE CONFIG { "apps": [{"id": 1, "name": "App1", "pids": [1979, 1980]}, {"id": 2, "cores": [4], "name": "App2", "pids": [1592, 1593, 1594]}, {"id": 3, "cores": [5], "name": "App3", "pids": [1576, 1577, 1578]}], "pools": [{"id": 1, "cores": [1, 2, 3], "name": "HP", "mba": 100, "cbm": "0xFF0", "apps": [1], "power_profile": 1}, {"id": 2, "cores": [4, 5, 6], "name": "MP", "mba": 50, "cbm": "0xC", "apps": [2, 3]}, {"id": 3, "cores": [7, 8, 9], "name": "LP", "mba": 10, "cbm": "0x3", "apps": []}], "power_profiles": [{"id": 1, "min_freq": 2500, "max_freq": 2500, "epp": "performance", "name": "HP"}], "auth": {"username": "admin", "password": "password"}, "sstbf": {"configured": false}, "power_profiles_expert_mode": false, "power_profiles_verify": true } "apps" section, Apps being managed by App QoS. - "id" - App’s ID - "name" - App's name (optional) - "cores" - cores being used by App (optional) - "pids" - list of App's PIDs "pools" section, Pools of Apps. - "id" - Pool's ID - "name" - Pool's name - "apps" - list of Apps being part of the Pool - "cbm" - Intel RDT CAT CacheWayBitmask assigned to Pool - "mba" - Intel RDT MBA rate [%] assigned to Pool - "cores" - cores being assigned to Pool - "power_profile" - Power Profile ID to be applied on pool's cores "power_profiles" section, Power Profiles/SST-CP. - "id" - Profile's ID - "name" - Profiles's name - "min_freq" - min. frequency [MHz] - "max_freq" - max. frequency [MHz] - "epp" - Energy Performance Preference "auth" section, REST API username and password. - "username" - username - "password" - password "sstbf" section, Intel(R) SST-BF configuration. - "configured" – SST-BF requested state NOTE: "power profiles" are ignored when SST-BF is configured. Global options: - "power_profiles_expert_mode" - make power profiles editable via REST API (Default: False) - "power_profiles_verify" - Admission Control feature for config file content, verifies Power Profiles and Pools configuration (Default: True) USAGE ===== AppQoS is a Python script accepting the following, optional, command line options: - -h, --help, show this help message and exit - -c PATH, --config PATH, Configuration file path - --port PORT, REST API port (default: 5000) - -V, --verbose, Verbose mode NOTE: AppQoS requires root privileges. By default it will attempt to read from "appqos.config" file from current folder. Example command line to run AppQoS in verbose mode and config file in non-default location: sudo ./appqos.py -c /tmp/appqos.conf -V NOTE: All required dependencies are installed and AppQoS is executed in virtualenv when started via "make run" command. For more information about configuration file please see CONFIGURATION paragraph, for information about runtime configuration please see REST API paragraph. For more info please see Step-by-step. REST API ======== The REST API is a local (but can be easily modified to allow remote access), secured interface that allows the user to control AppQoS. The REST API allows to: - add, remove or move App between Pools, - add, remove or modify Pools, - configure Intel(R) SST BF and CP technologies NOTE: None of configuration changes made via REST API are saved to configuration file. As REST API uses HTTPS, it requires SSL certificate, please see HOW TO GENERATE SELF-SIGNED SSL CERTIFICATE paragraph for more info. The REST API uses "Basic HTTP Auth", username and password are stored in appqos.conf. To set your own username and password please modify the following section of appqos.conf: "auth": {"username": "admin", "password": "password"} NOTE: If using curl to do REST API calls, add --user admin:password to command line REST API URIs ------------- JSON Schema files for REST API commands and responses are available in "./schema" directory. - GET /apps - get all/collection of apps - POST /apps - create new app Example request: {"pool_id": 2, "name": "hello", "cores": [1,2], "pids": [1]} Result: {"id": 5} - GET /apps/{id} - get app for given id Example response: {"id": 6, "cores": [2, 3, 11], "name": "App", "pids": [1748, 1749, 1750], "pool_id": 3 } - PUT /apps/{id} - update app (e.g.:move between pools) for given id Example request: {"pool_id": 2} - DELETE /apps/{id} - delete app for given id - GET /pools - get all/collection of pools - POST /pools - create new pool - GET /pools/{id} - get pool for given id - PUT /pools/{id} - modify pool for given id - DELETE /pools/{id} - delete empty pool for given id - GET /power_profiles - get all/collection of power profiles - POST /power_profiles - create new power profile - GET /power_profiles/{id} - get power profile for given id - PUT /power_profiles/{id} - modify power profile for given id - DELETE /power_profiles/{id} - delete power profile for given id - GET /stats - get stats - GET /caps - get system capabilities Example response: {"capabilities": ["cat","mba","sstbf","power"] } - GET /caps/sstbf - get Intel(R) SST-BF details Example response: {"configured": true, "hp_cores": [2,...,88], "std_cores": [0,...,95] } - PUT /caps/sstbf - configure Intel(R) SST-BF Example request: {"configured": true} USAGE SCENARIO ============== AppQoS, leveraging Intel(R) RDT (CAT, MBA) and SST (BF, CP) Technologies, is to be used prioritize and protect performance of high priority applications.
