I hope this is the right category under which to post this.
I’ve (temporarily) changed my IPFire to using a USB mobile router (PPP QMI) to connect to the internet. I have no Network (external) graphs although the other graphs are OK.
The error being logged is
Error in RRD::graph for ppp0: opening '/var/log/rrd/collectd/localhost/interface /if_octets-ppp0.rrd': No such file or directory (netexternal.cgi, ppp0, day)
Looking at that directory:
# ls -lst /var/log/rrd/collectd/localhost/interface/

which means, I think, the data is being logged into if_octets-ifb0.rrd as this is the most recently updated file.
Is there something I should edit to fix this?
I made the switch from “normal” ethernet red to ppp using setup. Does this have a bug?
Thanks @hvacguy I’ve just tried that … and no change. It’s still looking in the wrong place for the info (looking for /var/log/rrd/collectd/localhost/interface/if_octets-ppp0.rrd which doesn’t exist.

OK. Having checked on the box, the network metrics are being collected into /var/log/rrd/collectd/localhost/interface/if_octets-red0.rrd - rrdtool info is showing values for the most recent lines…
The defect looks to be in /srv/web/ipfire/cgi-bin/netexternal.cgi in the lines
if ($netsettings{'RED_TYPE'} ne 'PPPOE'){
if ($netsettings{'RED_DEV'} ne $netsettings{'GREEN_DEV'}){
push (@graphs, ($netsettings{'RED_DEV'}));
}
}else{
push (@graphs, "ppp0");
}
should I just add a check for RED_DRIVER eq 'rndis_host' ? Or the existence of /sys/class/net/ppp0 ?
Any advice welcome.
OK. That didn’t work - resulted in a 500 error, presumably because the graphs aren’t being built … so the same check is being made in the software elsewhere.
Where are these graph databases / tables populated?
… or is the error that I have a red0 interface device instead of a ppp0 i/f device?
