As opções de desempenho e escalabilidade e as práticas recomendadas são descritas na seção
Desempenho e
escalabilidade do Guia de integração entre o NetWorker e a VMware, disponível em:
https://www.dell.com/support/home/product-support/product/networker/docs
1. No NetWorker Server, crie um arquivo de entrada (exemplo: vmperf)
2. Preencha o arquivo de entrada com os seguintes detalhes:
. type: save job; vm_name: VM_NAME
sh vm_name; job output; start time; end time; job log file
p
Nota: Substitua VM_NAME pelo nome da VM afetada. Você pode obter essas informações na saída
mminfo -kot.
3. Usando a consulta de tarefas e o arquivo de entrada, podemos coletar detalhes sobre as horas de início e término da tarefa e informações de log da sessão de backup.
[root@nwserver ~]# jobquery -i vmperf
Current query set
end time: 1654567313;
job log file: \
/nsr/logs/policy/Gold/VMware/353252-winclient01-2022-6-6-19-1-53.log;
job output: Backup completed successfully.;
start time: 1654567245;
vm_name: winclient01;
end time: 1654480913;
job log file: \
/nsr/logs/policy/Gold/VMware/353027-winclient01-2022-6-5-19-1-53.log;
job output: Backup completed successfully.;
start time: 1654480845;
vm_name: winclient01;
end time: 1654394509;
job log file: \
/nsr/logs/policy/Gold/VMware/352801-winclient01-2022-6-4-19-1-47.log;
job output: Backup completed successfully.;
start time: 1654394446;
vm_name: winclient01;
4. As horas exibidas estão de acordo com o horário do UNIX, mas isso pode ser convertido com: date -d@UNIX_TIME
[root@nwserver ~]# date -d@1654394446
Sat Jun 4 19:00:46 PDT 2022
[root@nwserver ~]# date -d@1654394509
Sat Jun 4 19:01:49 PDT 2022
5. No caso dos backups com longa execução, analise o arquivo de log de tarefas para obter informações sobre o throughput:
[root@nwserver ~]# cat /nsr/logs/policy/Gold/VMware/352801-winclient01-2022-6-4-19-1-47.log | grep "DiskStats"
2022-06-05T02:01:48Z INFO: [@(#) Build number: 95] DiskStats: Disk Label | Mode | Bytes Moved | Read Rate | Write Rate | Overhead | VDDK Wait | Total Time | VM MORef | VM Name

Nota: Em dias em que o backup leva mais tempo do que o normal, a velocidade total de gravação é menor do que a média vista em outras sessões de backup.
6. Os logs de política para a VM específica podem ser analisados executando:
cat /nsr/policy/POLICY_NAME/WORKFLOW_NAME/*VM_NAME*.log | grep DiskStats
[root@nwserver ~]# cat /nsr/logs/policy/Gold/VMware/*winclient01*.log | grep "DiskStats"
2022-06-05T02:01:48Z INFO: [@(#) Build number: 95] DiskStats: Disk Label | Mode | Bytes Moved | Read Rate | Write Rate | Overhead | VDDK Wait | Total Time | VM MORef | VM Name

Nota: Os logs de política seguem a retenção do jobsdb (padrão: 72 horas). Depois que a janela jobsdb for concluída, os logs de política associados e as entradas de jobquery serão removidos. No entanto, o equipamento vProxy manterá os logs da sessão de backup da VM localmente, em /opt/emc/vproxy/runtime/logs/recycle/vbackupd/
