[rrd-users] Re: I would like graphics in bits.

[João Marques]

Hello Alberto,

I'm storing the numbers in bytes too, as the MIB gives it.
Then I'm using the following code to generate graphs in bits since 1 byte =
8 bits.
Notice that the CDEF's for max_incoming_kbits and max_outgoing_kbits are in
Kbits (multiply by 8 and divide by 1000)


  $command .= "DEF:incoming=$rrdfile:ds0:AVERAGE ";
  $command .= "DEF:outgoing=$rrdfile:ds1:AVERAGE ";
  $command .= "DEF:max_incoming=$rrdfile:mx0:MAX ";
  $command .= "DEF:max_outgoing=$rrdfile:mx1:MAX ";

  $command .= "CDEF:incoming_bits=incoming,8,* ";
  $command .= "CDEF:outgoing_bits=outgoing,8,* ";
  $command .= "CDEF:max_incoming_kbits=max_incoming,8,*,1000,/ ";
  $command .= "CDEF:max_outgoing_kbits=max_outgoing,8,*,1000,/ ";

Hope it helps!

PS: Você é de Portugal ? Eu sou do Brasil! Como vão as coisas por ai?
