SOLVED: No traffic graphs. intmacreceiverr in file name

[pupo888]

I'm having a problem getting traffic graphs to work with Cacti 0.8.6j installed using the Windows installer. I believe the problem is related to a plugin but am not sure how to fix it.

When I create a new device and then create graphs for the device the traffic graphs do not show up. CPU and memory usage for Cisco switches work fine, but traffic graphs do not. Looking at Graph Mangement and Data Sources I see that the graph is pointing to an rrd file which does not exist. On every traffic graph where I see this problem the graph points to devicename_intmacreceiveerr_number.rrd but the rrd file does not exist. I can't even find a file for the same device with a matching number, although other files are created, seemingly for the traffic ports. I don't know where the filename is coming from. Deleting the device and recreating does not solve the problem. The host templates I use are Cisco Router and Cisco 4500.

The error message in graph debug is:

ERROR: opening 'D:/Inetpub/wwwroot/cacti/rra/switch11_intmacreceiveerr_300.rrd': No such file or directory

Has anyone seen this before who might be able to point me in the right direction?

Thanks.

Edit: Upon further investigation it seems that this problem is not solely due to the filename. That problem may be due to a bad Cisco 4500 template. Could I be missing a graph template?

When I run the graph in debug mode the error above shows for all traffic ports. However when I check the data source that IS actually correct. Could a bad template somewhere be the issue?

I suspect you're not receiving any traffic data. Follow http://docs.cacti.net/node/283

[pupo888]

When I run an rrdtool info on the rrd files it looks like there is data being collected in them. I am also able to get interface traffic data just fine from my pix firewalls. That's why I am leaning towards some sort of problem with a template somewhere.

Just to confirm though here is the output of a rrdtool info. Can you please confirm if this looks like data is being collected?

How are you looking inside a rrd file (switch11_intmacreceiveerr_300.rrd) which you said doesn't exist?

Change the cacti logging level to debug for a single polling cycle; look to see if your cisco 4500 is returning traffic data. Also look for switch11_intmacreceiveerr_300.rrd and what is going on with that and rrdtool. If rrdtool is constantly trying to create the file, then that points to a NTFS permission problem.

[pupo888]

I'm simply looking at an rrd file which does exist but is also not graphing.

When I look at the data sources for a graph in Cacti they point to an existing rrd file. When I look at the graph through Graph Management for the same device and port the rrd file it references points to a non-existing rrd. Am I making sense? The data collection for a specific device and port appears to be correct, the graph portion for the same device and port is not.

I will try your other suggestion to see what it returns.

Thanks.

Here is the output of a graph debug. The rrd file with _traffic_in_236 exists, but the one with _intmacreceiverr_237 in the file name does not. Similar graph defs are created by deault for every device I add graphs to using the Cisco Router or Cisco 4500 host templates. Is there a way I can find out where these defs are coming from? I don't want the collison and mac data selected by default if they cause errors.

Thanks.

Problem solved. At some point I must have imported a graph template which overwrote or modified the default "Interface - Traffic (bits/sec)" template. That template had lots of extra defs for alignment errors, collisions, etc. and defined additional data sources. Deleting all those extra defs and data sources and just leaving the (traffic_in) and (traffic_out) defs and Inbound and Outbound data sources caused all traffic graphs to graph normally with the data that was being collected all along.

Thank you for your help BSOD2600.
