No data in new graphs, existing graphs work fine.

[Red]

I have a fairly new cacti install, that I've been working on as a side project. It's been set up for several weeks, graphing traffic from most our switches - World Wide Packets models LE-327, LE-317, and LE-46H (we also have LE-36 switches, but can't get traffic data from them). And our router, a Riverstone RS-3000.

After installing a new LE-46H, I have been unable to get anything to graph. I configured it same as all the others, using the generic SNMP interface queries, but nothing shows in the graphs. I activated two ports on the Riverstone, but the new graphs show no data, right alongside existing graphs which continue to work fine...

Ideas?

Have you tryed to set your poller logging level to DEBUG and then look in your logfile?

[Red]

I've done that, nothing is jumping out at me though.

1) are you able to see the basic snmp info from the device in cacti?
2) are you able to snmpwalk the device from the cacti box?

If no to either, then there is the problem.

I pulled this from the cacti logs, it is the new LE-46H that is not graphing:

I have not done an snmpwalk from the cacti server before, looked through the man page, and I'm still a little confused. Any particular way you'd like that run?

Thanks for your help and patience.

So it's collecting data, thats good.

1) Are the rrd files for host 40 updating?
2) Go go graph mangement, click on a broken graph, then click on graph debug. What is the error message?

[Red]

Here is the debug output. This port connects to a wireless bridge feeding a remote access point tower. That tower also has an LE-46H outdoor hardened switch, same model and software revision as this one. I am able to graph the other end of the bridge link from the remote LE-46H, and it is indeed moving traffic.

RRDTool Says:

OK

[BSOD2600]

Even though rrdtool says ok and you're returning traffic data, you're saying you don't have anything showing up?

[Red]

Indeed. That's why I'm here! And remember, it's doing this even on a device that I'm already graphing ports on. On the Riverstone router I just tried to add graphs for two more ports, all the prior graphs continue to work just fine.

[Red]

I set up another linux box with my spare PC at home and installed cacti. It graphs those host just fine. Go figure. I don't even know where to start looking on that first server.

[gandalf]

Two more advices: Increase php.ini's memory size from 8MB to at least 64MB. And do an rrdtool fetch <rrd file> AVERAGE on those rrd files specified by your graph debug posted above. Post the last 20 lines or so of both of them

Hi there, I'd like to note that everything posted above I have encountered and done.

Here's the last 20 lines of one of the rrds that was working, then suddenly stopped;

Please let me know what I should try next.[/quote]

This shows, that data was gathered some times ago. Please switch Settings -> Logging Level to DEBUG for one polling cycle. Then find the data input method in cacti.log for that host and check the output.
No output => sths wrong with data retrieval
Output ok but no update => sths wrong with updating rrd files
