Passing environment variable to SWA

[Raynald Boucher]

Hello all,

I'm new to SWA and trying to setup a process by which we can monitor multiple systems.
I'm currently attempting to pass a hostname to SWA using an environment variable so that the resulting output files can be uniquely identified (ex. _swa_analisys.xml).

Is there a way to do this other than writing a wrapper script that will invoke SWA with comand line options (ex. -x analisyz_file=${1}_swa_analisys.xml) where an environment variable or parameter can be actualized?

Here are my current results:

# grep SWA_HOST /etc/opt/swa/swa.conf
analysis_file = ${user_dir}/cache/${SWA_HOST}_swa_analysis.xml
html_report = ${user_dir}/report/${SWA_HOST}_swa_report.html
# export SWA_HOST=romulus
# echo $SWA_HOST
romulus
# var/opt/swa/cache/swa_inventory_3481069612.xml <

This may fail if SWA communicates with a demon, one that has already been started and can't possibly see your new environment variables.

Also, if /etc/opt/swa/swa.conf isn't a shell script, it won't do the substitutions.

So your wrapper idea seem like the only solution.

Yup,

I had thought that it would be permissable from references to ${user_dir} in the swa.conf file but it doesn't work so I developped a little script that works just file so far. Here it is if interested:

#!/usr/bin/ksh
#
# name swa_check.sh
#
# purpose To perform a security check on a given UNIX server
# and download required patches
#
# usage /usr/local/bin/swa_check.sh
#
# configuration See default configuration in /etc/opt/swa/swa.conf
# the -x options below override the configuration file
