The graph in insight is not displayed correctly

[fiterzs]

The graph in insight is not displayed correctly, it works fine when I clear the data, but it stops after a while (usually half an hour to an hour), but the flowd_aggregate service in the dashboard is running, /var/ The file size under the netflow/ directory is also changing. How to solve this problem? I'm confused
