O comando sar permite monitorar o desempenho de sistemas Linux, como CPU, mem\u00f3ria, I\/O, etc, em tempo real. \u00c9 poss\u00edvel tamb\u00e9m armazenar todos os dados de desempenho em uma base, analisando-os para identificar gargalos.<\/p>\n

Nas distribui\u00e7\u00f5es openSUSE e CentOS o comando sar est\u00e1 presente no pacote sysstat, podendo ser instalado pelo YaST\/zypper ou Yum, respectivamente.<\/p>\n

Os principais usos do sar s\u00e3o:<\/p>\n

    \n
  1. Uso da CPU (sar -u)<\/li>\n
  2. Uso de mem\u00f3ria (sar -r)<\/li>\n
  3. Uso do espa\u00e7o de swap (sar -S)<\/li>\n
  4. Atividade individual de cada dispositivo de I\/O (sar -d)<\/li>\n
  5. Atividade da fila de execu\u00e7\u00e3o de processos e carga (sar -q)<\/li>\n
  6. Relat\u00f3rio de estat\u00edsticas da rede (sar -n [DEV|IP|TCP|UDP|ALL])<\/li>\n<\/ol>\n

    Obs.: Existem outras op\u00e7\u00f5es no monitoramento da rede.<\/em><\/p>\n

    Para maiores informa\u00e7\u00f5es, aconselho a leitura da manpage do sar.<\/p>\n
