sysreport.sh

A Linux bash script useful for determining system resources and health.

I'm not actively working on this script but you can submit bug reports and suggestions for functionality. The best way to reach me is to contact me at my Mastodon account - https://mastodon.social/@crlamke.

Current functionality

1. Generates single file HTML report, useful for cron based automated run and email
2. Disk space stats
3. Top processes by CPU
4. Top processes by RAM
5. Docker stats
6. Recent package changes (e.g. yum or apt history)
7. Recent user history
8. Recent sys logs (currently only dmesg)

Planned functionality

1. Generate plain text report
2. Add apt history (currently only RHEL/CENTOS yum history is supported)
3. Add mem and disk deltas capability to bash monitor scripts (depends on data from each run being stored on machine)
4. Add more detailed container monitoring
5. Add color key below tables with colored elements

Requirements to run script

1. You must run this script as root/superuser.
2. This script outputs HTML and text results and requires the ability to write files to the current/run directory
3. Tools required for the script to fully run
   • systemd-detect-virt - to determine whether the script is running in a VM and if so what type of VM
   • getconf - used to determine number of processors online
   • column - used to format text output
4. This script fully supports RHEL/CENTOS 7 and partially supports Ubuntu 20.x LTS. More support will be added as time allows.
5. bash v4.2 or later
6. Note that tools like ps, sed, awk, etc. universally included in Linux distros are required for this script but not listed here.
7. mailx - Only if you want the email functionality

Optional components that will be reported if present

1. If docker is running, the script will provide information on docker containers (currently) with more info to be added.
