Live and SIOKIT collections have an option to capture performance data on a per-VM basis. This article provides
information on how to capture performance data on a per-VM basis and guidance on the following aspects:
- Performing the Collection
- Viewing the Results
Performing the Collection
Fig. 1 shows the upload options that allow capturing VM performance data. The VM performance data checkbox (Fig 2) has been added to the “Add Remote Server” selection window while running a LIVE or SIOKIT assessment. This checkbox is preselected when a vCenter assessment is made. When this checkbox is selected, Live Optics will conduct two concurrent assessments:
- Normal Live Optics assessment based upon the duration selected (10 min, 4hr, 8hr, 12hr, 1 day…7 day). This assessment collects upcoming or future data. This file will be called “LiveOptics_ProjectNumber_MM_DD_YYYY.xlsx”.
- A VM performance assessment that is estimated to take 3 to 5 seconds per VM will run in order. This assessment collects up to the last 24hour of data that is stored in the vCenter. The length of historical data recorded is set by the vCenter administrator. This file will be called “LiveOptics_ProjectNumber_VMware_MM_DD_YYYY.xlsx”.
Figure 1 VM Performance is only included in LIVE & SIOKIT options within Optical Prime
Figure 2 VM Performance option is displayed in the “Add Remote Server” window for connection to vCenter only
The VM Performance will run in parallel to the normal Live Optics collection run and both must complete for the overall assessment to be finished.
Viewing the Results
Once the assessment is complete the user will need to log on to the portal, go to the project that was run and select “Download to Excel” from the pulldown menu. This will result in a .zip file consisting of two Microsoft Excel files (normal Live Optics Excel file and VM Performance Excel file).
The VM Performance Excel file (LiveOptics_ProjectNumber_VMware_MM_DD_YYYY.xlsx) will consist of the following:
