i have some Cisco an Adtran routers using serial interfaces (ppp over ds1 and ds3) and none of them show traffic on the graphs. they all show traffic when i use the real time option though. the data files for rrd exist and all other interfaces graph correctly.
i would like to retire my old observium install but it’s fairly important that i can monitor these links.
