We have not seen any performance impacts on our Solaris servers with all the
logs turned on (except Server Group and Full Text Index which we do not use).
If you do a prstat on your server how much memory is the arserverd process
using?
The log options we use are:
Plugin Log Level: All
Log File Creation: Create Backup
Maximum Log File Size: 64M ( 64,000,000 )
Buffer Logged Lines: Unchecked
Log Per thread: Unchecked
The cron save script is basically:
#! /usr/bin/ksh
cur=`date +%H%M`
# Set the Script path
logpath=PATH_TO_LOG_FILES
savepath=PATH_TO_WHERE_FILES_SHOULD_BE_SAVED
cd $logpath
chmod a+r *.l*
#
[ -r arsql.log ] && cp arsql.log ${savepath}/arsql_${cur}.log ;
[ -r arfilter.log ] && cp arfilter.log ${savepath}/arfilter_${cur}.log ;
[ -r arapi.log ] && cp arapi.log ${savepath}/arapi_${cur}.log ;
# You get the idea on copying the files
#
cd ${savepath}
rm -f *${cur}.log.gz > /dev/null
gzip *${cur}.log
#
exit 0

Subject: Re: Impact on Enabling API/SQL Logs in Production environment
Vaibhav,
Thanks again, I am exactly concerned about the memory footprint going higher
where it could eventvually crash the server. Unfortunately we can't simulate in
our test envionrments since the user load will not be the same.
The server has high memory, but remedy 7.1 is 32 bit app and hence can't grow
beyond 4G and will crash when memory footprint goes beyond 4G.
Also Our environment is not load balanced it is just one server.
Missi,
Thanks for your inputs, I will check the "buffer logged lines" option when
enabling API and SQL Logs, but will enabling logs really cause any performance
impact?
Want to make sure user response time and ARS Memory foorpint doesn't get
impacted especially.
Fred,
Thanks for your inputs, i am planning something like you mentioned, but would
like to know if you ran into any performance issues
Regards
Sathish
