portanto, o memcached fornece muitas estatísticas para rastrear o uso (acertos e erros).

estatísticas em torno de get, delete, incr, delete estão presentes nesta lista. No entanto, meu aplicativo tem uso extensivo deadicionare que não possui nenhuma métrica específica para mostrar quando falha na atualização.
Como posso verificar quantos foram realmente adicionados e quantos não foram adicionados?
Observe que posso fazer isso no aplicativo - registrando, etc., mas estou procurando uma maneira de obter isso nas métricas de monitoramento do memcached.
Isso é possível?
