Hi,
just installed 0.10... tried to follow suggestions on this forum and in tutorial. snmp works, crons run without errors, rrd files are being written, I can see graphs, but cannot see any data. (trying to see bandwidth at my router).

Help please.

This sounds like an SNMP mis-configuration. Look in your lastrun.log file (usually found in /usr/local/var/log/netmrg/lastrun.log) for 'U's (capital). If you're seeing 'U's, it means that it couldn't gather data for that device.
An easier, but less accurate way of checking this would be to goto Groups, then click on your device, the subdevice for your interface, then look at the monitors; if they have a Value of 0, then you're probably not getting any data (of course, this could also mean that nothing is changing).
One last thing I could think of to check is that your subdevice is configured correctly; click on Groups, then click on your device name, then click parameters next the the subdevice for the interface on your router. You should see a parameter like 'ifDescr' with a value next to it. If not, add one (ifDescr, FastEthernet0/0, for example). Let it go a couple cycles to see if you get data.

Thanks... your last suggestion was the fix

I kept getting mysql errors while trying to add the parameter, but it seemed to start working anyway!

Yep... sorry about that. We're aware of that bug and it has been fixed for the next release (bug#73). You can try a sub_dev_param.php from CVS.

Thanks!
