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
