I currently have an issue where the Time Picker I am using is not displaying anything unless I specify All Time. Even then I still cannot see my most recent events.
The thing that baffles me is that I am using that same dashboard on another system and it works perfectly fine, I can see the most recent events as they come in.
I am using tokens for my time charts and passing in the time value from another dashboard, but I don't think that is the issue because If I click all time it works semi correct.
It is baffling to me too - perhaps if you provided more detail of what you are doing, e.g. SimpleXML, what works in your other dashboard and what is not working in this one, it might become clearer.
There was actually a issue with how the syslog data was being formatted. It was coming in without quotes.
