Pregunta
Cómo determinar la tasa de falla actual de una alarma en cualquier momento después del disparador inicial. La tasa inicial de fallos puede resultar más evidente, pero, ¿se encontraría posiblemente la tasa actual de fallos horas después?
Respuesta
Mientras que la trampa SNMP inicial, el registro y la alarma rastrean la tasa de falla inicial de un umbral monitoreado, puede que no sea obvio cómo obtener la tasa de falla actual. En la parte inferior de "show threshold", el comando informa del estado de todas las alarmas con respecto a la tasa de falla actual en el último intervalo de sondeo.
