I just did an install of zimbra 4.5.6 on a centos 5 server install. Everything went smoothly, everything appear to be running. Emails come through, are scanned for viruses and spam, so that is all good. The only thing that seems to not be working is statistics. I installed this server setup last night (about 15 hours ago now) and statistics still say "data are not yet available".
Where do I start to figure out what's going on?

zmcontrol status says everything is running. Are there logs I can check for errors? (Still getting to know this wonderful product)
