1. Run the scheduled task to import data into reports. If there is still no data in the reports, continue to step 2.
  2. In the database, search for these metrics that are used to stretch the topology from controller to station to cell:
    • RRCAttConnEstabReg for cell-specific metric (device ->siteid) inverse connection to station

    • VSIUBDLCongTime for station-specific metric (device ->cntlr) inverse connection to controller

    • VSRRCAttConnEstabRNC for controller-specific metric
  3. To view the log files for errors, go to Centralized Management and click Collecting > Collector-Manager::<instance name> > Log Files.
