Looking deeper I found that although rrd database was created properly it wasn't updating properly. So I recompiled rrdtool 1.4.5 for my ubuntu box, and mystically it started working.

Even in simple testing I couldn't get rrdupdate to throw an error message, so I'm still not sure what was wrong, but recompiling fixed it.

Sorry to bother you with a non Observium problem.

I think the rrds appear to have data in them.  I haven't dug around in rrd much, but there appears to be defintions with valuse and averages being calculated.

Is there data in the RRDs? (rrdtool dump)

I recently installed Observium to monitor some voip switches. Previously I have had a different installation monitoring a ton of network gear, so I'm not unfamiliar with the intall process.  This new installation appears to be gathering data, but all my graphs are just axis and legends and all the number are "NaN".

Ubuntu 8.04 32 bit php5 5.2.4 myslq 5.0 rrdtool 1.4.3 snmp 5.4.1

Which is all the same as other the working system.

Debugging :

poller.php appears to be running fine and collecting data :

Polled in 5.111 seconds UPDATED! MySQL: Cell[0/0s] Row[114/0.01s] Rows[17/0s] Column[0/0s] Update[116/0.57s] Insert[1/0s] Delete[0/0s]

And the /device/#/ports/details/ page for my switch shows bandwidth numbers for each port, but completely blank mini graphs, and when I mouseover the mini-graph, it show graphs without any data, just axis, legend, and "NaN" for each value.

Apache error logs don't show anything failing.

Adding "&debug=1" to any of the graph.php pages, generates the same graphs without any data.

I've checked file/path permissions, and they appear identical between boxes.

Assuming user error, I've dropped the database and recreated it, along with a complete fresh install.  Neither helped.

I'm rather stumped, anyone have any ideas of what to look at next?
