The error No data available migh be found when you run a report using network node manager iSPI Performance for Traffic
Due to a change in the way in which Traffic data is processed by NPS and a defect in retention period set for different Traffic report extension packs (Interface_Traffic, Interface_Traffic_1_min, Interface_Traffic_15_min), this problem is happening. Starting version 9.20, Traffic SPI will only store raw data in the tables for all extension packs. Summarization of data will be done on-the-fly during a report launch so that ETL performance is not affected in continuously summarizing the data for Traffic - which is generally very large in volume. While doing this, there was a missed change in which Raw data storage was to be increased to 30 days and 400 days for 1min and 15min extension packs. For Interface_Traffic extension pack, the raw data will still be stored only for 7 days.
