NVP vProxy: Feilsøke VM-sikkerhetskopieringsytelse og -gjennomstrømming

Summary: Det finnes mange faktorer som kan bidra til VM-sikkerhetskopieringsytelsen. Denne KB-en gir en oversikt over hvordan du går gjennom VM-sikkerhetskopieringsøkter for mønstre i tiden det tar å fullføre en sikkerhetskopi av en angitt VM, og gjennomstrømming som observeres under sikkerhetskopieringer. ...

Instructions

Alternativer for ytelse og skalerbarhet og beste praksis er beskrevet i delen Ytelse og skalerbarhet i integreringsveiledningen for NetWorker VMware, som er tilgjengelig via: https://www.dell.com/support/home/product-support/product/networker/docs

1. Opprett en inndatafil på NetWorker-serveren (for eksempel: vmperf)
2. Fyll inndatafilen med følgende detaljer:
. type: save job; vm_name: VM_NAME
sh vm_name; job output; start time; end time; job log file
p
Merk: Bytt ut VM_NAME med navnet på den berørte VM-en. Du kan få denne informasjonen fra mminfo -kot output.

3. Ved hjelp av jobbspørring og inndatafilen kan vi samle inn informasjon om start- og sluttidspunkter for jobben og logginformasjon for sikkerhetskopieringsøkten.
[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. Klokkeslettene som sendes er i UNIX-tid, men dette kan konverteres med: 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. Hvis du vil ha sikkerhetskopier som har en lang sikkerhetskopi, går du gjennom jobbloggfilen for å få informasjon om gjennomstrømningen:
[root@nwserver ~]# cat /nsr/logs/policy/Gold/VMware/352801-winclient01-2022-6-4-19-1-47.log | grep "DiskStats"

Merk: På dager der sikkerhetskopieringen tar lengre tid enn vanlig, er den totale skrivehastigheten lavere enn gjennomsnittlig for andre sikkerhetskopieringsøkter. 

6. Policyloggene for den spesifikke virtuelle maskinen kan gjennomgås ved å kjøre:
cat /nsr/policy/POLICY_NAME/WORKFLOW_NAME/*VM_NAME*.log | grep DiskStats
[root@nwserver ~]# cat /nsr/logs/policy/Gold/VMware/*winclient01*.log | grep "DiskStats"

Merk: Policyloggene følger oppbevaring av jobsdb (standard: 72 timer). Når jobsdb-vinduet har passert de tilknyttede policyloggene og oppføringer for jobbspørring, blir de fjernet. vProxy-verktøyet beholder imidlertid logger for VM-sikkerhetskopieringsøkte lokalt under /opt/emc/vproxy/runtime/logs/recycle/vbackupd/
