GetConfig is specifically designed to be non-intrusive.
It will not impact system performance as even on slow systems it only take between 1 & 10 minutes to run.
It will only take longer if you have large HSSM, HTnM or HDvM logs.

GETCONFIG INSTRUCTIONS
##################################################################
# SILENT (NO OPTION) MODE
##################################################################

# ./getcfg <casenumber> -s  <output destination>

*note: 
<casenumber> is the HDS case number including prefix
-s is for silent mode 
<output destination> is optional. If not specified /tmp is used.

In silent Mode, ALL defaults are accepted

##################################################################
# SILENT (NO OPTION) VERBOSE MODE
##################################################################

# ./getcfg <casenumber> -s -v <output destination>  >/tmp/output.txt 2>&1 &

*note: 
<casenumber> is the HDS case number including prefix
-s is for silent mode 
-v is for verbose mode 
<output destination>    is the destination directory


You may use any combination (-sv) or (-vs) 
It is strongly advised to add the >/tmp/output.txt 2>&1 & to capture
the output and run the script in the background when running it with the 
verbose option.

You may also leave out the mode flags to specify only an output 
destination

For example:

# ./getcfg <casenumber>  <output destination>  


This way you may run

# tail -f /tmp/output.txt 

to view the results real-time while the getconfig completes.
