Dear Expert

NagiosXI 5.2.x
CENTOS 6.x.x.x
snmp -v 2c

MaxBytes : 960000 <<<<< 9Mbps
12500000 <<<<<< 100Mbps
125000000 <<<<<< 1000Mbps = 1Gbps
1250000000 <<<<<< 10Gbps
3150000000 <<<<<< 25Gbps
12500000000 <<<<<< 100Gbps

FYI ,, MaxBytes we adjusted as above.

rrdtool performance graph
its working fine till 10Gbps, however now we have 100Gbps METRO Ethernet routers/switches, will handle properly to plot the graph?

i mean, we added 100Gbps ports / interfaces, graph will plot perfectly upto 100Gbps? without any issue? can you please confirm?

regards

I faked a 200Gb port speed and the wizard/cfgmaker was able to detect it and display it properly.

It should be able to graph it properly. Are you seeing issues with the graphing on it?

dear ssax

i think u did not get my point, in/out traffic pattern will get plotted? will not torn? SNMP version 2c will handle (HighBitCounter) will handle?

as you know
ifInOctets ,, ifOutOctets cannot plot more than 100Mbps graph, SNMP version 1
so we all using now a days SNMPv2c .... ifHCInOctets ,,, ifHCOutOctets to plot more than 100Mbps graph so me asking
ifHCInOctets ,,, ifHCOutOctets will handle smoothly to plot 100Gbps graph?

32-bit = 2^32-1 = 4294967295.
64-bit = 2^64-1 = 18446744073709551615. <<<<<<< just by looking this much big value.....looks YES will plot 100Gbps easily without any issue
, however me asking the confirmation from you Experts.

how u did fake 200Gbps graph? can you attach (embed) 200Gbps graph? or can you show any real graph of any of user (suing NagiosXi 5.2.x version) and plotting 100Gbps or 200Gbps.

regards

Are you having trouble with your graphs or are you just asking whether they will have issues?

Are these new routers/switches or are you already monitoring the devices with the Switch/Router wizard and are now adding 100GB ports to them as well?

MRTG queries the routers and will check the high speed counters first so it should work properly. If this is a new router/switch running the Switch/Router wizard should pick them up properly, add them to the /etc/mrtg/conf.d/X.X.X.X.cfg properly, and then graph them properly. You can see here for more info on it.

The RRDs just insert numbers so they won't be an issue.

I faked it with snmpsim:
