[SOLVED] Problem with over 100MBit/s Outbound Graph

[Bokin]

Well, see the Picture. It say more then my bad english words

Actually the Server have an Outbund of 140Mbit/s

Why there are nox graph painted?

Thanks for your help

[cplvic]

You graph is displaying "Bytes" and not "bits".
Bandwidth is usually measured in bits.
8 bits = 1 Byte

So for your graph the CURRENT is 9MB which is 72Mb (9MB * 8 = 72Mb).

When you change your graph see if you can poll your device using SNMPv2 for 64Bit counters. This is for high speed interfaces that are equivalent to 100Mbps or greater.

Hope this helps/

Hello,
well measuring in Bit with a 10GBit Line is not really good
SO Byte is my favorite.
Its also anaway with my problem. The Graph is down at this moment i reach a high Outbound. As Bits or Bytes the same.

I already use SNMPv2 with 64Bit Counters. But it doesnt works how you can see.

Other suggestions?

[Bokin]

Here some more infos:

Its a download Server
Interface: 1Gbit at Cat 6 900Mhz Cable
OS: Debian Etch 64 Bit
CPU: DualCore E4500 with a 0,10 load
Ram: 2GB (90% free)

I have no idea where the problem is.
rrdtool at cacti server is version 1.0.49 but it works with all other interfaces pretty well.

Please see 2nd link of my sig and pay attention to MAX issue
Reinhard

[Bokin]

Ok, thank you. I will try and report later

[Bokin]

Ok have checked all Points and nothing find that is wrong.

Now i have updatet rrdtool to the newest one (1.2.27) but no changes.

Is there anyway to reconfigure cacti?

[gandalf]

Ok have checked all Points and nothing find that is wrong.

Fine. But what where your findings? If the graph shows NaN, there is no valid data in the rrd file. Either rrdtool update hit the MAX or it was never performed. So I really need some details of your debugging process

[Bokin]

Hello Gandalf,
first many thanks for your support.

After i have updatet rrdtool to 1.2.27 it doesnt works. The i have deletet all the rrd files and run the poller cron to create a new on.
This was 8 hours left and now it seems to be work. Maybe in the afternoon the bandwidth will rise up the mistake will come again. But i think and hope not.

[Bokin]

Ohhh damn, after i transfer a filoe with 50MB/s (~400Mbit) the same shit continous.

I habe thousands of "nan".

Look at this please:

I hope that will help.
Can you give me an example what i must do to enter a new value?
Again, the Interface is an 1000Mbit (1GBit)

Thank for your help

[gandalf]

That clearly show the MAX issue. From your rrdtool info

ds[traffic_in].max = 1.0000000000e+07

And the data clips at exactly this boundary. Please either increase it or deactivate it (see man rrdtune)
Reinhard

[Bokin]

I would like increase but have no idea what value i have with an 1Gbit Interface.

1.0000000000e+07 <<< think this for for 100Mbit but how looks the value for 1Gbit (1000Mbit)?

[gandalf]

1E+8
To be honest, this is not literally correct because data is measured in Bytes, not in bits (like ifSpeed).
Reinhard

[Bokin]

Nowww it finally works.

ds[traffic_out].max = 1.0000000000e+10

74MB/s the HDD is Hotruning
