Graph for each VM in vCenter is showing data only for 1 day. I want data for 1 week and 1 month also. How to make it available for greater than 1 day? I tried to change custom setting for graphs but data is unavailable.
Also, statistical level is set to 4 for all the fields.
Are you using SQL Server as the vCenter database? If yes, can you confirm if the SQL rollup jobs are running? See the following VMware KB article: "Performance data is currently not available for this entity" error after updating rollup in vSphere...
