When you work in tech support department and deal with inexperienced clients debugging problems turns into a nightmare. As a sysadmin, you won’t become too paranoid if less experienced people have root-access. As a consultant, you wonâ€™t feel isolated if you donâ€™t have remote access to your systems. As a support engineer, you wonâ€™t become frustrated if a customer has fiddled around with some important config file and you have to find which. As a performance tuner, you can capture the state of the system configuration in between performance tests/benchmarks.
Luckily, some nifty tools can create a system’s hardware and software configuration snapshot. This kind of information is valuable asset while troubleshooting problems.
dconf (System config collector) is one of such tool. It allows to take your system configuration with you on the road, compare identical systems (like nodes in a cluster) to troubleshoot HW or SW problems, indeed a lifesaver.
Dconf is also useful in projects where you have to manage changes as a team. Dconf can run periodically and send out system changes to a list of email addresses so that they can be revised and discussed in group.
You can customize your dconf configuration for specific needs, like making a profile of your web serverâ€™s hardware or copy specific software configuration files to send out or compare with other systems.

If you are using Debian / Ubuntu Linux then type the command:
# apt-get install dconf
You can download Dconf for RedHat or Suse Linux here
Create a system’s hardware and software configuration snapshot
Once installed you can simply create a snapshot using dconf command:
It will write snapshot in /var/log/dconf/ directory. To view current snapshot info, enter:
# zcat /var/log/dconf/dconf-$HOSTNAME-latest.log.gz
To check the latest changes against the previous snapshot:
# zdiff -u /var/log/dconf/dconf-$HOSTNAME-previous.log.gz /var/log/dconf/dconf-$HOSTNAME-latest.log.gz
- Linux display system hardware status information gathered from /proc filesystem in easy format
- FreeBSD : Display information about the system
- Read man page of dconf for more information
- Offical Dconf home page
