Light-weight alternative to `df` (without SNMP)
Overview:
I'm looking for a way to get usage data for all mount points (UFS,VxFS & NFS) on a Solaris system. I'm starting with `df` but would like to find something that might be more light-weight.
Background:
Using SNMP is not an option in this case, instead I need to use basic built-in commands to get the data. The commands must be present on SPARC and x86 platforms and our minimum release level is Solaris 8, newest is 10. I will be writing a script or program (don't need help with that) to get the disk usage statistics and then report on partitions that are low on space. The script will run automatically and on systems where mount points tend to hang or disappear without notice so I'll need to fork df for each mount. The additional processes, some which may get orphaned, might be a resource problem so I want to at least minimize the resource footprint of each command that is run.
I am fully ready to accept that`df` may already be the best way to approach this but I wanted to ping the community just in case.

Hello,
We had a problem on a Solaris system (SunOS 5.10) that hit LWP limit and caused fork 11 error. Now we need to come up with a script to simulate and reproduce that scenario. What would be a simple and valid way to generate lots of Light Weight Processes?
Thanks,

hol-light
HOL-LIGHT(1) General Commands Manual HOL-LIGHT(1)
NAME
hol-light - HOL Light interactive theorem prover
SYNOPSIS
hol-light [options...]
DESCRIPTION
The command hol-light is a simple wrapper for calling ocaml and loading the HOL Light basic definitions (by loading /usr/share/hol-
light/hol.ml instead of .ocamlinit as initialization file). Loading these definitions takes about 2 minutes on modern hardware, please be
patient. All options and other arguments are passed as options to ocaml.
If you have a readline-editor such as rlwrap, ledit or rlfe installed, the hol-light ocaml toplevel is wrapped in readline-editor. Install
just one of these readline editors or configure your preferred one via the alternative system.
SEE ALSO
ocaml(1), readline-editor(1), rlwrap(1), ledit(1), rlfe(1)
