SuSE 11: porcentagens de CPU "superiores" não são adicionadas

2

Executar "top -b" no meu sistema SLES 11sp2 produz a saída abaixo. A linha Cpu (s) reporta 33,7% de uso da CPU no espaço do usuário, mas se você adicionar a coluna% CPU na listagem de processos, você só terá 4,9% de uso.

Li respostas a perguntas semelhantes que dizem "o topo oculta alguns processos, o htop para ver todos". Instalar o htop não é uma opção neste ambiente de cliente, então estou apenas procurando entender o que é que o top pode esconder, por que e como ver a utilização da CPU de todos os processos usando o conjunto de ferramentas padrão do Linux.

Obrigado.
