Problem this snippet solves:

This is a script utilizing the Graphviz package that will create graphs of the relationships of configuration objects of a virtual server.

How to use this snippet:

Requirements

1. Perl
2. SOAP::Lite
3. Net::Netmask
4. Graphviz

Note: There are other required packages, but the remainder are default in Ubuntu 10.10 perl distribution. This may not be the case with your configuration.

1. Install dependent libraries via apt-get - depending on your distribution you may have all of these as packages:
   • libssl-dev
   • libcrypt-ssleay-perl
   • libio-socket-ssl-perl
   • libgraph-writer-graphviz-perl
   • libsoap-lite-perl
   • libnet-netmask-perl
2. For any which aren't available, open a CPAN shell (perl -MCPAN -e shell) and install them with commands such as:
   • install SOAP::Lite
   • install Net::Netmask
3. Grab the archive below, extract the perl script file, and make it executable

Minimal command-line invocation is:

• ./f5-gl.pl -t bigip-host-name.your.domain -u userid -p password

The output by default goes into a subdirectory img, but you might want to add the option -d output-directory to keep output files separate from successive runs, particularly if you will run the utility against different BIG-IP systems for different operational environments. You can also use these:

• -c partition -v vs

  to run for only a particular VS (the partition must also be given)

• -e

  to change the output file type - default is JPG, but there are the options of SVG or PNG

Run it!

Put it in

/etc/crontab

If you are averse to command-line parameters (perhaps you don't want the password to appear in a process listing) you can instead update these variables in the script:

• my $ltm_host

• my $user_id

• my $user_password
