bluesky.plans.monitor_context

bluesky.plans.monitor_context(plan_stack, signals)

Asynchronously monitor signals, generating separate event streams.

Upon exiting the context, stop monitoring.

Parameters:

• plan_stack (list-like) – appendable collection of generators that yield messages (Msg objects)
• signals (dict or list) – either a dict mapping Signals to event stream names or simply a list of Signals, in which case the event stream names default to None
• name (string, optional) – name for event stream; by default, None

Examples

>>> plan_stack = deque()

With custom event stream names

>>> with monitor_context(plan_stack, {sig1: 'sig1', sig2: 'sig2'}):
        ...

With no event stream names

>>> with monitor_context(plan_stack, [sig1, sig2]):
        ...
