How do I get the last sensor run time of a sensor instance?

To get the last sensor run time of a sensor instance, you can refer to the

last_tick_completion_time

attribute available in the

SensorEvaluationContext

. This attribute represents the last time that the sensor completed an evaluation, and it is provided as a float representing a UTC timestamp. Here is an example of how you might access this attribute within a sensor definition:

python from dagster import sensor, SensorEvaluationContext  @sensor def the_sensor(context: SensorEvaluationContext):     last_run_time = context.last_tick_completion_time     # You can use last_run_time here to inform your sensor's logic     ...

The

last_tick_completion_time

is one of the properties you can use to understand when the sensor was last evaluated. Keep in mind that this timestamp is in UTC, so you may need to convert it to your local timezone if necessary.
