RRDTool Showing NAN

patoy · 07-03-2008, 09:12 PM

I'm kinda new to rrdtool. the problem is it does not display data on the graph, only NAN values. Basically the perl script behind that graph is working fine in the command line, it shows values. Any recommendations how to resolve this issue?

was able to get to work with the graph but not all are still working. all i did was place the perl script to run intervally on cron. any idea? i'm also double checking if the rrd database really receives real data and not the NAN value.

the above statement is resolved. now the other problem is rrdtool db is already receiving data from the script ran through cron however it will not display any data in the graph, it still shows nan value. any help?

can you dump the data in the rrd itself to check that there is actually any valid data in there?
