Instructions

O rastreamento de Storport mede o tempo que o subsistema de disco de um computador leva para concluir as operações de E/S. As medições são obtidas do storport.sys, um driver de porta de armazenamento que é adequado para uso com barramentos de alto desempenho, como Fibre Channel, iSCSI e adaptadores RAID. O storport.sys é o último componente na pilha de armazenamento do Windows antes que a operação de E/S seja enviada ao HBA de armazenamento. Um rastreamento de Storport é útil ao tentar isolar a causa de um problema de desempenho (camada de software, controlador de armazenamento, discos rígidos, SAN e assim por diante).


Para coletar um rastreamento de Storport:

  1. Execute o seguinte comando para criar o rastreamento de Storport no monitor de desempenho. O rastreamento será iniciado automaticamente depois de executar o comando:
 logman create trace "storport" -ow -o c:\perflogs\storport.etl -p "Microsoft-Windows-StorPort" 0xffffffffffffffff 0xff -nb 16 16 -bs 1024 -mode Circular -f bincirc -max 4096 -ets
  1. Depois que o problema for reproduzido, execute o seguinte comando para interromper o rastreamento do Storport:
 logman stop "storport" -ets
  1. Para converter o log para o formato .csv que pode ser visualizado no Excel, execute o seguinte comando:
 xperf -i C:\PerfLogs\storport.etl -o C:\PerfLogs\storport.csv -tle -target human
