When the context exceeds this threshold, a log will be made. :param log_mode: Control whether to log. Defaults to "threshold". Possible values include: "always" - Always log 'msg', even when 'threshold' is not reached. "threshold" - Log when context time exceeds 'threshold'. "skip" - Do not log. Context time and message are stored in the 'output' and 'delta' attributes, respectively. Used to manually coalesce with other logs at the call site. usage: this call: ``` with Timed("Configuring the network"): run_configure() ``` might produce this log: ``` Configuring the network took 0.100 seconds ``` �{�G�z�?� threshold�r �log_mode��msgr r c C s( || _ || _|| _d| _d| _d| _d S )N� g )r r r �output�start�delta)�selfr r r � r �9/usr/lib/python3.9/site-packages/cloudinit/performance.py�__init__% s zTimed.__init__c C s t �� | _| S )N)�time� monotonicr )r r r r � __enter__3 s zTimed.__enter__c C s� t �� | j | _d| jd�d�}d| jkr<t�d| j|� nZd| jkrJd S d| jkr�| j| jkr�t�d| j|� | j� d|� �| _ nt d | j� d ���d S ) Nztook z.3fz seconds�alwaysz%s %s�skipr � z Invalid Timed log_mode value: 'z'.) r r r r r �LOG�debugr r r � ValueError)r �exc_typeZexc_valZexc_tb�suffixr r r �__exit__7 s �zTimed.__exit__N) �__name__� __module__� __qualname__�__doc__�str�floatr r r r r r r r s �� r r r r r c s � ��fdd�}|S )a� A decorator which measures and optionally logs context run time. :param msg: A message that describes the thing that is being measured :param threshold: Threshold, in seconds.
