You start to get problems around half that or 7Mbps as you've seen. 10GigE just is more likely to have more traffic. > Is anyone using jffnms to graph 10 GigabitEthernet?

Quite a few versions do, to some degree. 0.9.2 is more explicit about it. I'd hold off going to 0.9.2 for now, there were some bugs in that you may see depending on your equipment fleet. The good news is they're all fixed and the pollers run a lot more smoother. 0.9.3 is all about fixing the pollers and removing some of the caching problems people have seen. All of them (bugs, fixes and speed-ups) are due to the way the pollers work now, by interface and not host, but its a better way of doing it. I'm very lucky now to have someone with a reasonably sizeable fleet of equipment testing the version in git which has ironed out a lot of problems. - Craig -- Craig Small VK2XLZ http://enc.com.au/ csmall at : enc.com.au Debian GNU/Linux http://www.debian.org/ csmall at : debian.org GPG fingerprint: 5D2F B320 B825 D939 04D2 0519 3938 F96B DF50 FEA5 ------------------------------------------------------------------------------ This SF email is sponsosred by: Try Windows Azure free for 90 days Click Here http://p.sf.net/sfu/sfd2d-msazure _______________________________________________ jffnms-users mailing list jffnms-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/jffnms-users
