No Historical DATA exist on VRealize 6.02 After reinstalling the vcenter

Hi All ,

Your support is highly appreciated ,,,,,

Case description :

- I have 2 vcenter servers 5.5 and 1 vcop 5.8.5 and Vrealize 6.02 .

- 2 vcenters adapters were added (registered ) to VCOP 5.8.5 and where working fine (collecting data)

- installed Vrealize 6.0 and imported the data from existing VCOP 5.8.5

-"deletenonexisting " was set to false which means that data will not be purged or removed from database in case if adapters were removed from VCOP

- I was planning to upgrade the vcenters from 5.5 to 6.0 update 1 but instead of uninstall linked mode before upgrading vcenters  ,I uninstalled the vcenter (unfortunately no backup was taken ). Big Big Big mistake was made when you complete such tasks and talk with friends or colleagues  and pressing  on next next next and this is the result

- I decided to install new vcenters version 6.0 update 1 using same FQDN and IP and here started the problems:

-In VCOP 5.8.5 become foundation instead of standard because it was licensed with removed vcenters as asset with standard license

-Historical Data of the virtual machine become invisible 

-Report Tab was removed

- VROP 6.0 automatically registered the new vcenters and started collecting data as normal but again no Historical data shown since the date when the old vcenters reinstalled.

- to move from foundation license to standard I installed temporary vcenter instance and registered with VCOP and applied the standard licenses

- now missed tabs came back but historical data invisible on VCOP

How can I see historical data again  or retrieve them from database ???

Any workaround to solve this issue??

Can I do anything to extract some data from database? attached screenshot of available command related to database

Thanks

You've got a few moving parts there, but the skinny on the historical data is - by installing vCenter your UUIDs have changed on your objects, so they're essentially different objects to vR Ops.. so there is a hard line between "old" and "new" data within vR Ops. The purging criteria in vR Ops v6.x would eval the data based on the last collecting time of the objects and clean it up appropriately (set int he global settings). I don't see how your data pruning is set for objects (global settings) that no longer exist, but I'd expect it to be pruned out and dropped from the FSDB if you did nothing. You can't granularly set the pruning settings in vR Ops, as it is global, so you're going to eventually lose that data unless you want to sacrifice the quality of the rest of the data in the system (you've got this old data you may want to keep, however you're live data source still generate garbage that needs cleanup). If you want to see your old objects, take a look in Inventory Explorer and see if you can find them.. by name, object type etc. If the objects from your old vCenter instance aren't in Inventory Explorer, they're gone and never coming back.

If you find this or any other answer useful please mark the answer as correct or helpful.
