Um dos meus scripts de monitoramento HAProxy não está funcionando em uma nova caixa HAProxy de configuração. Eu rastreei o problema na saída do soquete de estatísticas, e não no próprio script.
Estou recebendo valores de "0" relatados por meio do soquete, mas os valores corretos da interface da Web.
Alguém pode explicar as diferenças na saída?
