Hi,
Hope someone can help.
I'm seeing a lot of errors in fresh installed vCenters Servers (internal SQL Express and other vCenter with external Oracle 11g). The stats.log states
tomcat-http--15 ERROR com.vmware.vim.stats.webui.chart.StatsChartServlet] Unable to generate performance chart image. Details: Error while drawing chart report.
com.vmware.vim.stats.exporter.ReportExportException: Error while drawing chart report.
I found several kbs about "Performance Tab", but none of them solved this issue. The two scenarios are very different but the error is the same...what's wrong?
Here's a little bit more of info.
vCenter Server 5.1. Simple install in both scenarios
No AD integration
1 scenario (oracle) with DNS the other one with IP addresses only
Self-signed certificates in both cases
There are so many errors in stats.log and in other logs from "tomcat" and "vcenter" that I don't know what to post
. Here's another one from stats.log

Caused by: com.vmware.vim.stats.cil.ChartDrawingException: Error while streaming JFreeChart image.
at com.vmware.vim.stats.impl.cil.jfreechart.JFreeChartImageLibrary$1.write(Unknown Source)
... 27 more

Please help!
