Recently I was reading an internal posting and also found out through my colleague Josh Gray @jasper9, on Twitter that in vCenter 5.1 the Performance History is not retaining any information beyond 30 days. (which is only a month worth of data).
Now such performance data is crucial for getting the analysis done for so many things.
At present the issue is being investigated by VMware.
The issue is discussed here in KB 2042164.
@duncanyb has posted a blog here.
The alternate solution is put forward my @vcdxnz001 on this post here about using vCOPS Foundation.
Apart from it if you have a monthly backup of vCenter VM (complete VMDK) or the VC Database (either SQL or Oracle) then have the backup verified again and if possible make another copy of them. (individual monthly backup copies). So if you need for last one years performance history then you need 12 monthly back up copies of the vCenter Database. Depending on the requirements you can go and use the back up for any performance history retained in the database. Mainly if there is a new install of vCenter Server 5.1 then this should be for few months only as vSphere 5.1 released in October 2012. It does affect to both instances of fresh install of vCenter Server and an upgrade of vCenter Server from an older versions to 5.1.
I suggest to use the option of "Subscribe to Document" on the KB page to get notification when the fix is released.
