Las métricas basadas en registros cuentan las entradas de registro que coinciden con un filtro determinado para el proyecto actual. Por ejemplo, podrías crear una métrica para hacer un seguimiento de la cantidad de viajes creados a lo largo del tiempo con la siguiente consulta:

Configura alertas
Puedes crear alertas para notificar a los clientes cuando una métrica se salga de un umbral definido y especificar los canales de notificación para esas alertas. Consulta Configura políticas de alertas basadas en registros.
