----
If you find that you repeatedly instrument a suite of metrics across components or applications, you may encapsulate this suite in a `MeterBinder` implementation.
If you metrics depend on other beans, it is recommend that you use a `MeterBinder` to register them, as shown in the following example:

include::{code-examples}/actuate/metrics/SampleMeterBinderConfiguration.java[tag=example]
----
Using a `MeterBinder` ensures that the correct dependency relationships are set up and that the bean is available when the metric's value is retrieved.
By default, metrics from all `MeterBinder` beans will be automatically bound to the Spring-managed `MeterRegistry`.
A `MeterBinder` implementation can also be useful if you find that you repeatedly instrument a suite of metrics across components or applications..
