netstat graph on redhat es release 3 and hpux 11.00 🔗 link

Hi all,

i have problem on graph netstat0 (network I/O bits second)on my lunux box: all the values are 'nan'.
It's used the ifconfig output to create this graph?

These is my ifconfig output:

 eth0      Link encap:Ethernet  HWaddr 0F:FF:22:33:10:3F
          inet addr:xxx.xxx.xxx.xxx  Bcast:xxx.xxx.xxx.xxx  Mask:xxx.xxx.xxx.xxx

          RX bytes:2727990196 (2601.6 Mb)  TX bytes:2727990196 (2601.6 Mb)
There is something different from other linux version?

On my hpux box :
on netstat1 graph the values UDP In/Out Datagrams are 'nan'
on netstat2 graph the values TCP Failed Attemps and TCP Established Reset are 'nan' 
on netstat3 graph the value TCP Established Connections is 'nan'

Probabily the output from my netstat command is different 

thanks for yours helps

    Hi all,

    i have problem on graph netstat0 (network I/O bits second)on my lunux box: all the values are 'nan'.

    On my hpux box :

    on netstat2 graph the values TCP Failed Attemps and TCP Established Reset are 'nan' 
    on netstat3 graph the value TCP Established Connections is 'nan'

    Probabily the output from my netstat command is different 

    thanks for yours helps

Hi,

I got exactly same behaviour here whith redhat as 2.1, 3 and 4 and hpux. 
On the hobbit server, in rrd-status log I got the following message :

Host pioupiou reports netstat for an unknown OS
Host xxxxxx reports netstat for an unknown OS

I even got these messages for machine under aix or solaris...
Sincerly,

Thomas

No, it uses the "netstat -s" output. Linux doesn't do byte-counts for
the TCP/IP statistics, only on the entire network interface. So the
"netstat0" graph is not valid on Linux.

In Hobbit 4.2, you will have an "ifstat" graph tracking the number of
bits passing through your network interface.

What does your "netstat -s" output look like ? I have a pattern matching
for this where Hobbit looks for a "datagrams received" and "datagrams
output" line.

AFAIK, these counters are not reported by HP-UX.
