Hi!

I have moved Cacti to new server and its running Version 0.8.8h. Some of the graphs are working.
I deleted interface bit/sec graph and using In/out bits 64 bit counter. After that all the cisco routers are showing NAN on the graphs. I am running snmpv2 on cacti.

Anyone suggest some solution to this?

Thanks

Have you been able to work it out? After migration of the Cacti server I have been encountering this very same error with cisco routers.

What is the host status? If it's not 'up' you have an issue with polling. Check the crontab settings. If 'up' but 'nan', then check the file permissions. I had similar until I ran 'chmod +x /usr/share/cacti/ -R' to allow file execution on all files below the cacti directory. Check the file time/date stamp on the RRD files to see if they are being updated.
