Name

syssheet -- System Sheet Script to display system information

Synposis

syssheet [-g|-c|-f]

Description

The MDVL System Sheet Script gives a one-screen system overview. It consists of the following panes:

General Information : Displays the current user name, the terminal type the script is running on, kernel and architecture information, date and time, hostname, uptime, RAM usage and CPU types. Network : Displays the physical interfaces, their addresses (if assigned) and the amount of data transmitted/received. File systems : Displays a subset of the mountpoints visible by df. For each mountpoint, the amount of data used and total available space is displayed. If quota is installed and quota are set, the current quota usage is displayed below the file systems. Users : Displays the top process in terms of memory and the top process in terms of CPU usage for each user

Options


-g Draws the sheet using continuous lines instead of - and + signs. -c Colorizes the output -f Combines the effects of -g and -c

Output of syssheet -f / Screenshot

Rationale

This script is intended to be usable as a script to start by default in a new terminal. It makes sense for local, as well as remotely connected systems.

For local systems, it provides all basic troubleshooting information on a single screen, for remote systems, it immediately gives an idea about the current utilization of the system (e.g. other users performing compute-intensive tasks etc.)

Syssheet is intended to be smaller and run faster compared to some alterantives like inxi at the expensive of providing only a fixed set of information. Data from mountpoints and network interfaces is presented in a way which attempts to mainly include physical filesystems and network interfaces as not to obsucre the view by container mountpoints and interfaces. Compare the outputs of ip link and mount against the typical syssheet-report to see the difference.

Integration with Bashrc and System

To build a Debian package for this script, invoke ant package. If no package is needed, everything is included in file syssheet and thus in a suitable form for copying to remote systems. The only noteworthy dependency is gawk.

You can add syssheet to your bashrc as described in the following.

Add the following at the begin of the file:

[ -z "$PS1" ] && return # Terminate when not running interactively
export LINES
export COLUMNS
/usr/bin/syssheet -f &
sheetpid=$!

Add the following at the end of the file:

( sleep 3 && kill $sheetpid ) 2>&1 > /dev/null & sleeppid=$!
disown
wait $sheetpid
kill -s TERM $sleeppid 2> /dev/null
unset sheetpid
unset sleeppid
echo

These snippets start a syssheet in the background and stop it, if it does not complete within three seconds. The time limit is important to avoid hangs due to slow mountpoints. Adding the snippets in the begin and end respectively, allows all other bashrc parts to run in parallel to the syssheet.

Bugs

  • Running without gawk produces garbled output.
  • Terminal needs to be at least 80 characters wide.
  • Memory reports need to be considered approximations.
  • Performance improvements welcome.
