Many of the collectors are internally calling functions/methods which expect a context. In those cases we usually pass
context.TODO()
because there is no context passed from the caller.Introduce context to the methods
NewCollector
andGetMetrics
such that it's easier to use a passed context. For now we still passcontext.TODO()
from the caller, but eventually we can use a context with timeout where it makes sense.
