Olá Rogério,

Bom, depende do tipo de verificação que você deseja fazer. Se for uma verificação simples, da máquina na qual você está utilizando, no Windows 2000, 2003 e XP existe o Windows Monitoring Performance (WMP) que pode ser acessado pelo: painel de controle -> ferramentas administrativas -> desempenho.

Agora se você deseja contruir uma ferramenta para verificar a utilização da CPU em um rede de computadores, além das opções acima cidadas você pode dar uma olhada na Java? WBEM (JSR48) 1.0.0 API, que é o que há de mais atual hoje para o gerenciamento de redes de computadores atualmente.

Um abraço.

Conforme solicitado...

zepunk,

Acredito que o erro esteja na classe CLStat, pois quando executo ela passando parâmetros dá certo.

Utilizando a classe com essas alterações...

e executando através da linha de comando com:

Mas como não sou entendido vou no assunto vou postar a classe como você solicitou.

Já sei que essa excessão trata do acesso de uma posição inválida do array, porém, estou com dificuldades para saber que posição é essa.

E quanto a suposta linha 14, a classe CLStat não tem uma linha 14 =/

Obrigado pela atenção!

Olá amigos,
