scfdot - Generate a graphviz file of SMF services and dependencies

The Service Management Facility (SMF) is responsible for managing services

and service start order in the Oracle Solaris operating system. Run

"man smf" for more information. scfdot reads the service names and

dependencies from the Service Configuration Facility (SCF) repository

and writes a file which the dot program from the graphviz package can

render into a graph.

Once graphviz is installed and dot and cc are on your path, you should be able

to generate a PostScript file of the dependency graph on your system by

running

$ make

This will compile scfdot.c, execute it, and execute dot to produce

$HOSTNAME.ps. If dot is not on your path, then modify Makefile to indicate

how to invoke dot. If cc is not available, add a line to Makefile which sets

CC to how to invoke your compiler.

To view the graph with gv, I recommend

- The -noantialias option. Otherwise the black labels on the colored

backgrounds look bad.

- Adding a 1/100 zoom option to gv and using that for the initial view.

Otherwise gv will ask your X server for a ton of memory, which can cause

it to thrash. Add the option by putting

GV.scales: Natural size, 1.000, screen \n\

Pixel based, 1.000, pixel \n\

0.010, 0.010 \n\

0.100, 0.100 \n\

0.125, 0.125 \n\

0.250, 0.250 \n\

0.500, 0.500 \n\

0.707, 0.707 \n\

1.000, 1.000 \n\

1.414, 1.414 \n\

2.000, 2.000 \n\

4.000, 4.000 \n\

8.000, 8.000 \n\

10.00, 10.00

in ~/.gv . Make it the initial view by including "-scale -6" in the

command line.

The Makefile also has options for changing the command line arguments to

scfdot. See the comment at the top of scfdot.c for available options.

Makefile - Makefile for building scfdot, running it, running the

scripts, and running dot to produce a PostScript file of

the dependency graph.

scfdot.c - C program which generates dot files.
