I'm running ZCS 5.0.16_GA_2921.UBUNTU8 UBUNTU8 FOSS edition on a Ubuntu 8.04 System. The Server is running for one week now, but i still get an Error with the logger!

If i go to Server Statistics, there are these "Data not yet availible"-Images instead of the Graphs..

And if i go to Server State, a message is shown, that i have to install the Logger-Server first!

zmcontrol status says, that all Services are running!

I've read, that the Cron's maybe are the problem...where can i check this?
