NVP vProxy: Problemen met vm-back-upprestaties en doorvoer oplossen

Summary: Er zijn veel factoren die kunnen bijdragen aan de prestaties van de VM-back-up. Dit KB-artikel biedt een overzicht van het controleren van VM-back-upsessies op patronen in de tijd die nodig zijn om een back-up van een opgegeven VM te voltooien en de doorvoer die wordt waargenomen tijdens back-ups. ...

Instructions

De opties en best practices voor prestaties en schaalbaarheid worden beschreven in het gedeelte Prestaties en schaalbaarheid van de NetWorker VMware Integration Guide, beschikbaar via: https://www.dell.com/support/home/product-support/product/networker/docs

1. Maak op de NetWorker-server een invoerbestand (bijvoorbeeld: vmperf)
Arabisch cijfer. Vul het invoerbestand in met de volgende details: 
. type: save job; vm_name: VM_NAME
sh vm_name; job output; start time; end time; job log file
p
Opmerking: Vervang VM_NAME door de naam van de betrokken VM. U kunt deze informatie verkrijgen viade uitvoer van  mminfo -kot .

3. Met behulp van taakquery en het invoerbestand kunnen we informatie verzamelen over de begin- en eindtijden van de taak en informatie over de back-upsessielogboeken. 
[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. De uitgevoerde tijden zijn in UNIX-tijd, maar dit kan worden geconverteerd met: datum -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. Voor back-ups die een lange back-up uitvoeren, controleert u het taaklogboekbestand voor informatie over de doorvoer: 
[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

Opmerking: Op dagen waarop de back-up langer duurt dan normaal, is de totale schrijfsnelheid lager dan het gemiddelde in andere back-upsessies. 

6. De beleidslogboeken voor de specifieke VM kunnen worden gecontroleerd door:
cat /nsr/policy/POLICY_NAME/WORKFLOW_NAME/*VM_NAME*.log | grep DiskStats uit te voeren 
[root@nwserver ~]# cat /nsr/logs/policy/Gold/VMware/*winclient01*.log | grep "DiskStats"

Opmerking: De policylogboeken volgen de jobsdb-retentie (standaard: 72 uur). Nadat het venster jobsdb is geslaagd, worden de bijbehorende beleidslogboeken en jobquery-vermeldingen verwijderd. Het vProxy apparaat bewaart echter logboeken van VM-back-upsessies lokaal onder /opt/emc/vproxy/runtime/logs/recycle/vbackupd/
