SysInfo: a set of scripts that document your system

**danger@** · #1 April 8th, 2009, 17:34

Hello guys,

I am developing a script that automatically documents settings of particular freebsd (currently 7.x) box from the hardware point of view to the network and services related information.

The point of this script is to provide some descriptive information about unknown system's configuration (hardware and software) for administrator who has no idea about the given system.

I would greatly appreciate if you guys could test it in your environment and provide some feedback. It currently doesn't provide very much information, so I would really also like to hear your opinions on what kind of information would you be interested in in above described situation, which I should document.

The latest version of this script can be found at:
http://people.freebsd.org/~danger/sysinfo/

Thank you.

I get an error in the part handled by the 020-mem script.

thx, useful fiche
P.S. btw in my opinion, it will be useful if script check rc.conf and after what check runing services and show status. smf like this:
apache 2.2.1 - runing
samba 3.3.3 - runing

I also get an error in the memory section:

Code:

expr: illegal option -- 1
usage: expr [-e] expression
expr: syntax error

I threw a few extra lines into 020.mem to see the values of the memory variables:

Code:

physmem: 3744890880
activemem: 140959744
inactmem: -1125810176
cachemem: 142274560
allmem: -616513536
wiremem: 211468288
freemem: 13770752

and the direct sysctl outputs (done after the script ran, so the results might be a little different) are:

Code:

hw.pagesize: 4096
hw.physmem: 3744890880
vm.stats.vm.v_active_count: 34425
vm.stats.vm.v_inactive_count: 773958
vm.stats.vm.v_cache_count: 34531
vm.stats.vm.v_page_count: 898060
vm.stats.vm.v_wire_count: 51683
vm.stats.vm.v_free_count: 3258

Seems to be an overflow error for memory above a certain size.

**danger@** · #7 April 9th, 2009, 08:27

interesting...I will check later today and see what's going on. I have been developing this tool on 8gb box, so it's a bit weird. We will see.

**danger@** · #8 April 9th, 2009, 08:29

Yup, the services part is not yet implemented. I will be working on this part today or maybe during the weekend and Easter holidays.

Having that said, I would like to hear what kind of information you guys are interested to see in the script's output in that regard.

Thanks.

**danger@** · #9 April 9th, 2009, 10:16

what does % expr 3744890880 / 1048576 give you?

That gives 2047. Although the problem seemed to be with multiplication, not division.

While reading the expr man page, I noticed the -e option, to detect overflows. I added it to the script, and no longer get errors:

ifconfig output parsing not adopted for point-to-point interfaces.

Maybe resolv.conf should be printed in network information.
Also, information about firewall could be useful (as for ipfw - at least sysctl net.inet(6).ip(6).fw.enable, net.link.ether.ipfw and net.link.bridge.ipfw variables).

P.S.: `./sysinfo -a | less` full of esacpe sequences used for coloring which makes output some less readable.

P.P.S.: thanks for developing such tool
