Hi All,

We get very large performance logs in the form of CSV.

We do lot of excel sheet work to generate graphs out from them.

I used rrdtool to generate graphs from them, but rrdtool does data normalization and won't graph the exact data(that is my understanding, correct me if I am wrong)

I used gnuplot, Gruff, scruffy . But I don't know whether they are suited for big data sets

this CSV file has only 25 lines

Still I get the alert

root@test-vm-lubuntu: ./plot.gp > latency.png
Warning: empty x range [-6.27983e+10:-6.27983e+10], adjusting to [-6.34263e+10:-6.21703e+10]
"./plot.gp", line 26: warning: Too many axis ticks requested (>1e+07)
"./plot.gp", line 26: warning: Too many axis ticks requested (>1e+07)


Please suggest if any other tool which can handle the big CSV files.

My Idea is to automate the whole graph creation using RUBY scripts.

Regards,
