Atualização 2

Havia umerro no Opscenter que não corresponde à configuração do dsc22 com a versão da comunidade cassandra, isso resolveu um problema.

Atualizar

Depois de ler o log do opscenter novamente, acho que há algo errado com os 4 campos de autenticação ou com alguma configuração ssh, mas ainda não sei o que exatamente deve ser feito. O campo diz "Chave privada de credenciais do nó local (sudo) (opcional)

o cenário é o seguinte:

Eu instalei 4 nós com vagrant e ansible onde cada um tem dsc22, opscenter (redundante eu sei), datatax-agent, cassandra-tool, oracle java 8configuração abaixostatus de nodetool, tudo é bom, todos se vêemEu crio um espaço de chave, ele replica para todos os nós muito bemna minha máquina host, abro o datatax usando a porta encaminhada do node02, por exemplo.Primeira vez que vejo duas opçõesadd existing cluster oumanage existing one Quando tento gerenciar o cluster existente> adicionar 192.168.50.3, recebo o seguinte:Então, eu tento usar 127.0.0.1, ele funciona muito bem, mas eu vejo apenas este nó cassandra local da máquina.Então, tento adicionar nós de dentro quando recebo uma caixa de diálogo (Eu acho que isso é importante) ele possui campos de credenciais que eu adiciono admin, admin para repositório e também admin, admin para nome de usuário local. Na verdade, não sei o que colocar nesses 4 campos, sejam eles criados ou pré-configurados em outro lugarEntão, depois de adicionar algum nó ao datacenter com informações sobre o RAC, etc., recebo o "Cluster de provisionamento de erros: o ID da solicitação é inválido"

Não tenho idéia de onde está o problema, a única etapa desconhecida que fiz foi a credencial (nome de usuário / senha do repositório, nome de usuário / senha local) quando adiciono nós de dentro. Mas por que não consigo gerenciar o existente desde o início, onde só entro quando uso 127.0.0.1 como ip.

Então aqui está o agente datatax:
