Background: The figure ran for one months, the other graphs can be displayed normally, but there are a few pictures suddenly not out of the picture;

Through RRDtool RRD view, all are Nan;

The solution that has been tried:

• Failed to restart SNMP---
• CACTI Rebuild---Failed
• Some people on the internet say that the deletion of the reconstruction is really so, but these pictures are business figures, cannot be deleted.
• Check db table, all OK;
• Network, system, bottleneck analysis, OK;

Finalization scenario:

• Write script timed rrdupdate;
