For some time the system board displayed data but something happened and stopped displaying it. Now System board looks like this: ![image](https://us1.discourse-cdn.com/flex023/uploads/influxdata/original/2X/2/20c39937014baeeb755d4719f0d4595c5eefba88.png) My questions: 1. How to completly reinstall and setup InfluxDb 2.0 from the begining (I can’t do this, always InfluxDb starts from existing configuration after removing and instaling again InfluxDb) 2. I added ads-b template (I have installed and working FlightAware with dump1090 and dump1090exporter, everything works flawlessly, I have aircraft positions from my ADS-B radar), but as for the System board in the ADS-B Flight Tracker board there is no data despite the fact that with dump1090 export generates them. What is wrong in my InfluxDb 2.0 installation? ---

Hello @marekpow, Have you tried changing the date selector to be from the past 7 days? Here are the file system layout defaults: > **[InfluxDB file system layout | InfluxDB OSS 2.6 Documentation](https://docs.influxdata.com/influxdb/v2.0/reference/internals/file-system-layout/#file-system-layout)** > > The InfluxDB file system layout depends on the operating system, package manager, or containerization platform used to install InfluxDB. ---

Yes, but there is no new, actual data, only for one day, few days back: ![image](https://us1.discourse-cdn.com/flex023/uploads/influxdata/original/2X/f/fbf5feaa0afaa103ae5533df49c628cf946fbd07.png) ---

Hello @marekpow, That sounds like telegraf isn’t reporting any more not like there’s a problem with InfluxDB. Have you tried restarting telegraf with the config from that template? ---

Hello @marekpow, It looks like you need to create a new token, and export it. I recommend going back into the UI under telegraf configurations and clicking setup instructions, It will walk you through doing just that. ---

Hello @marekpow, You can create a token and edit the config and replace it with the token you’ve created. Then you can set the environment variable permanently in your bash\_profile.
