synopsys - A SYNOPsis of your SYStem

The goal is to create an overview of a system. Instead of running:

• uptime
• dmesg | tail
• free
• vmstat
• mpstat
• iostat
• sar DEV, TCP, ETCP
• top

Show the critical parts from each of those in legible fashion with a single command.

Some might say this breaks the one-tool philosophy but i disagree, this isn't intended to

Ideally this would be doable from a single command that doesn't need to be pre-installed so either a script or self-contained binary.

Because any scripted language (e.g. python, lua) doing this would require either a ton of boilerplate or a long list of dependencies that might not be available to a sysadmin during a critical outage I'm favoring something that's easy to build/store/distribute as a single binary so even if it's not resident on a struggling system a simple the tool is only a simple scp synopsys away

These are the parameters I'd like to show

• Uptime
• CPU: cores, overall % useage, then % sys, usr, guest, ...
• wonders any way to make mpstat type of info here?
• Number of processes: run|able, sleep, unint sleep, zombies
• 'Errors' from dmesg and ~ dmesg | tail (or journalctl -b | tail)
• Memory: free/used
• Swap: free/used
• Disk activity: rw/wr in MBs and queue size
• Network In/Out (per device?)
• connections - active, passive, trans/retrans stats
• top 'few' processes consuming CPU | memory

initially this will just output some rolling format. will have to think about something like a tui to properly place things for readability though
