Tintri VMstore UI

Description

When viewing the system performance graphs on the VMstore UI, the top contributors list on the right hand side displays out of date or misleading information. When opening the performance graphs page, the date and time will match the current date and time. 

 

In the example below, the list of VMs shows many VMs that have actually been powered off and are no longer generating IO.

Details

 

This is a known issue on the VMstore performance graph, whereby when no date/time value is selected initially, the graph will default to the peak value seen in the previous 7 days. 

This behavior has been identified and an enhancement to this behavior will be introduced in an upcoming release of Tintri OS.

You should be able to click on the 'realtime' line or elsewhere on the graph (and then drag left to show the realtime stats) in order to display the current top contributors. After clicking on that line, the time should change to the nearest 10 minute interval (which can take place at any one minute in that 10 minute period), and the list of contributors should change to match the correct data. 

 

In the example below, the list of contributors has been updated after clicking on the 'Realtime' line. Note the time has changed also back to the previous 10 minute interval. The list of VMs has completely changed.

Final Review:
This is a well written KB. Except for this statement:
'This behaviour has been present in the code for a while unfortunately, but Tintri are developing an enhancement to this behaviour in an upcoming release of Tintri OS.'

I've updated it to:
'This behavior has been identified and an enhancement to this behavior will be introduced in an upcoming release of Tintri OS.'

Moved to Final.
