Estou com um problem em um compute instance no OCI, e o support me solicitou um OSWatcher para analisar o ambiente.
Diante disso como eu não tinha nenhum documento facilitando uma busca rápida, resolvi escrever este post para pode ajudar outras pessoas que no momento de necessitarem de uma consulta rápida não precisem ficar se matando para achar as informações.
Vamos lá para nossa instalação.
Relatórios de desempenho do Oracle OSWatcher
A ferramenta OSWatcher é uma ferramenta muito interessante que coleta e mantém dados estatísticos dos recursos do sistema operacional periodicamente e nos reporta. Você pode baixar e usar o software OSWatcher do suporte Oracle.
OSWatcher (Doc ID 301137.1)
OS Watcher User’s Guide (Doc ID 1531223.1)
A ferramenta OSWatcher executa alguns comandos como TOP, iostat, vmstat, netstat em determinados intervalos e mantém esses dados no servidor.
Instalação do OSWatcher
Passo 1: Baixe o OSWatcher e extraia-o conforme a seguir.

Passo 2: Para iniciar a ferramenta OSWatcher, execute startOSWbb.sh como a seguir.
startOSW.sh <SnapshotInterval > <ArchiveInterval>
Por exemplo; Se iniciarmos o OSWatcher como sh startOSWbb.sh 60 10, então o OSWatcher vai coletar dados a cada 60 segundos e manterá esses dados por 10 horas.
Por default ele inicia a coleta com intervalo de 30 segundos e mantém os logs por 48 horas.
