We've noticed that our performance graphs do not graph at all when the Check Interval is every 24 hours (we are handling this by setting the check interval to 60 minutes and using timeperiods to only allow it to check once every day). Once the service is changed to check every 10 minutes, graphing returns to normal.

Any ideas?

To create a graph in XI, the minimum the check interval can to be set to is 8 hours or less. Any longer that that, there is not enough data points in a day to create the graph.
