Time Series Virtualization dont see data

[Fei_Yao]

I can clearly see the Time Series data in Elasticsearch like below, but Im struggling to see those in either Timer Series Virtualization or Timelion. I thought it is super easy after I got the data into Elasticsearch, but don't know whatever I need to pay attention to, please help!

Thanks

A couple things: I see you have "Last 30 minutes" selected in the time-filter. Do you have data which is contained in that timeframe? Second, what index-pattern is selected under the "Panel Options" tab?

2. But if I want to aggregate other data it won't show up, Im not sure why.

If you want to graph mem within the same time frame, here is what you see:
