### Regular MRTG monitoring
0,10,20,30,40,50 * * * * root
/usr/local/etc/mrtg/exec_mrtg.sh > /dev/null 2>&1
we have ng_bridge, (bridged: fxp0, ngeth(1-xxx), hatm0)
ngethxxx are linked with hatm0 in the following way:
hatm0<->atmllc<->ng_vlan<->ng_eiface<->
we've tried tens of variuos configurations on determining the couse of those
fluctuations. They seems to be not only in ng_bridge but in kernel.bridge as
well. We've tried to change all 3 parameters in ng_bridge and still - those
parameters doesn't seems to affect fluctuations.
Currently used parameters on ng_bridge are:
# ngctl msg ng_bridge: getconfig
Rec'd response "getconfig" (2) from "[10f]:":
Args: { debugLevel=1 loopTimeout=1 maxStaleness=900 minStableAge=10 }
as you see, no loops or loop drops are detected on any ngeth interafce as well:
# ngctl msg ng_bridge: getstats 6
Rec'd response "getstats" (4) from "[10f]:":
Args: { recvOctets=3036543055 recvPackets=9193928 recvMulticast=75871
recvBroadcast=26 xmitOctets=9532655926 xmitPackets=51347925
xmitMulticasts=43833729 xmitBroadcasts=2174530 }
