Hi guys,
I have problem with graphing traffic graphs for one of my Observium monitored device; problem occurs when it comes to graph traffic for asymmetric interfaces - ones that only send or receive traffic. The problem is that when such interface is queried on the device for actual traffic values the response is:
for only-sending interface: Rx OID -> noSuchInstance, TxOID -> actual bits for only-receiving interface: Rx OID -> actual bits, TxOID -> noSuchInstance
Those values as used then to populate corresponding RRD file which results in series of "NaN"s for INOCTETS or OUTOCTETS data stores. The result is that traffic graph plotted from this RRD is corrupted - like this example: http://i66.tinypic.com/7281fo.png
Currently my Observium instance is at revision 7167. Could you share with me any ideas how to resole this issue?
Thank you & Regards! Pawel
