Starting AICM

Install Dependencies

AICM files are located in: 

/opt/qti-aic/tools/aic-manager

AICM requires several Python packages to run.
We recommend installing the dependencies in a virtual environment: 

python -m venv <path-to-the-virtual-environment>
source <path-to-the-virtual-environment>/bin/activate
pip install -r requirements.txt

Start Agent

After activating the virtual environment, AICM can be started using the following command: 

python aicm_agent.py

optional arguments:
  -h, --help                      Show this help message and exit
  --config_file                   Path to the Config file.
  --dump-default-config,          Dump the default config to the specified folder
    --dump_default_config_users   and exit.
  --dump-default-users,           Dump the default users file to the specified
    --dump_default_users          folder and exit.
  --ip                            IP address to bind to
  --port                          Port number to listen on
  --log                           Path where to store logs
  --max-log-size, --max_log_size  Max size of logs in bytes
  --ssl-key, --ssl_key            Path to the SSL key file. Needs to be provided
                                  for HTTPS.
  --ssl-cert, --ssl_cert          Path to the SSL certificate file. Needs to be
                                  provided for HTTPS
  --qmonitor-ip,                  IP of QMonitor GRPC Server
    --qmonitor_ip                 provided for HTTPS.
  --qmonitor-port,                Port of QMonitor GRPC Server
    --qmonitor_port
  -u, --users                     Full path to the users credentials file (.yaml)
  -v, --verbose                   Increase output verbosity

These settings can also be supplied via a configuration file.
If both are found, then the command line arguments will take priority.
The configuration file can be supplied via the --config_file option.

# AICM Configuration

# IP to bind AICM
ip = 127.0.0.1

# Port to bind AICM
port = 9000

# Full path to users credentials file
# users =

# SSL Key path
# ssl_key =

# SSL Certificate path
# ssl_cert =

# Path to directory where to store logs
# log =

# IP of QMonitor GRPC Server
qmonitor_ip = localhost

# Port of QMonitor GRPC Server
qmonitor_port = 62472

# Max sizes of logs in bytes
max_log_size = 100000000

# Verbosity of AICM agent
verbose = 0

AICM can also be run in a service-like manner : 

sudo bash scripts/start_aicm_agent.sh

Once running, the APIs can be tested at <ip>:<port>/docs through the SwaggerUI.

Stop Agent

The following command will stop the agent when scripts/start_aicm_agent.sh was used to start it: 

sudo bash scripts/stop_aicm_agent.sh
Alternatively, pressing Ctrl+C will stop AICM if it's running using the python aicm_agent.py command.

Setup Basic Auth

Since Basic Auth is used as the authentication method, users will need to authenticate all requests to our API.

The accepted credentials are stored in the .users.yaml file.

You can add/modify the credentials using the following syntax:

credentials:
  - username: admin
    hash: $2b$12$rEQTKF4IVHKPyeX6miseJ.xOjhmI5OFqlLuwE2OB4CuEIvHC2IFP6
    note: "Example of credential"
These credentials will be needed in every request made to the HTTP Rest Endpoints. For security purposes the password is hashed using bcrypt. A script used to get the hash is provided at /scripts/hash_password.py
Replace <password> and run this command: 
python ./scripts/hash_password.py <password>

HTTPS

Basic Auth is just a simple mechanism for authentication. For added security, running HTTPS is recommended, which requires users to provide a certificate and key upon startup. This can be done by passing the following args:

  --ssl-key SSL_KEY    Path to the SSL key file. Needs to be provided for
                       HTTPS
  --ssl-cert SSL_CERT  Path to the SSL certificate file. Needs to be provided
                       for HTTPS
