Re: [Monitorix-general] Network Traffic and Usage Problem Graph, FreeBSD
Hello Sean,

it appears that the format of the netstat -i output changed in FreeBSD
8 to include that 'Idrop' column.
So, perhaps an easy way to fix this is to use different code to process
the output for netstat -nibd based on the version of FreeBSD used? I've
attached a patch which seems to do the trick for me.
I've looked the patch and it seems that only covers FreeBSD version 7.x
and 8.x, but I'm not sure if FreeBSD versions prior to 7 (6.x, 5.x, ...)
could be also covered under the 7 condition.
Also, assuming the 'Idrop' column will continue existing from now on,
the next version 9 won't be covered by this patch forcing to add another
patch to the code.
I was thinking to use right now something like:
if($kernel_branch 7.2) {
# has 'Idrop' column
} else {
# don't has 'Idrop' column
}
This will ensure that even versions prior 7 could be supported assuming
they still have the same column layout as the 7 version. So they should
work without any problem.
Also it ensures that assuming the 'Idrop' column will exist in newer
versions, they will be covered as long as the FreeBSD guys don't include
an extra column.
Let me know what do you think about all of this.
Many thanks.

Hello Jordi,
Quoting Jordi Sanfeliu jo...@fibranet.cat:
I've looked the patch and it seems that only covers FreeBSD version 7.x
and 8.x, but I'm not sure if FreeBSD versions prior to 7 (6.x, 5.x, ...)
could be also covered under the 7 condition.
Sorry, I did not take those into account as I don't have those
versions to test so I was not sure if they include the 'Idrop' field
in their netstat output.
As a quick note, from what I know FreeBSD always has three versions
supported at one time, at the moment, that is 7 (legacy), 8 (standard)
and 9 (experimental, next generation). As far as I can tell, this
means any version older than 7 is no longer supported by security
patches or the ports system. So I'm not sure if you want to support
versions earlier than 7, but it is up to you. It is easy to do it in
this case but if there are other issues with FreeBSD that are version
dependent, it might be an issue then.
Also, assuming the 'Idrop' column will continue existing from now on,
the next version 9 won't be covered by this patch forcing to add another
patch to the code.
I was thinking to use right now something like:
if($kernel_branch 7.2) {
# has 'Idrop' column
} else {
# don't has 'Idrop' column
}
This makes sense. It should work for most future versions as well. I
Should have taken that into account!
Best regards,
Sean
