Import Data in Analysis Tool for Custom Graphs Not working

Hi,

We are monitoring AIX servers. Getting System resource Usage stats through VMstat and then formatting accordingly to cvs format as below. When tried to Import, Incorrect file format message popping.

date,time,r,b,avm,fre,re,pi,po,fr,sr,cy,in,sy,cs,us,sy,id,wa,pc,ec

Please can you share any sample csv file which was uploaded or let me know what mistake i'm making?

Thanks,
