Я пытаюсь отправить данные в Prometheus из моего приложения Spring Boot, используя аннотацию @Timed от Micrometer, и наблюдаю странное поведение. Я вижу данные моего метода в Prometheus, но я также вижу, что в некоторых случаях происходит сбой, за исключением ниже. Я включил необходимые библиотеки и следовал инструкциям по настройке Spring Boot для добавления аннотации Micrometer @Timed. Похоже на ошибку Spring Boot / Micrometer при создании ключей для metri c. Моя временная аннотация очень проста:
@GetMapping(value = {"/pageable"}, produces = MediaType.APPLICATION_JSON_VALUE)
@Timed("employees.get.pageable")
public Page<Employee> all(@SortDefault(sort = "id", direction = Sort.Direction.ASC) Pageable p) {
return (Page<Employee>) employeeRepository.findAll(p);
}
Есть идеи, что я могу делать неправильно? Я буду рад ответить дополнительным конфигом, но не хотел вставлять сюда весь свой проект. Трассировка стека:

java.lang.IllegalArgumentException: Prometheus requires that all meters with the same name have the same set of tag keys. There is already an existing meter named 'companies_get_single_seconds' containing tag keys [class, exception, method]. The meter you are attempting to register has keys [exception, method, outcome, status, uri].
