Health

Health is a command-line system status check tool written in bash 3.2+. Designed for Red Hat Enterprise Linux (RHEL) environments, Health provides an easy way to display general system statistics, scrutinize file systems for common errors, and check for a variety of other typical system issues.

Status Update:

• I will be away for work for all of July. I expect to work out any small bugs with the changes below in that time, and push a release upon my return.
• Focus on RedHat Enterprise Linux: The script is now focused on RHEL version 7+. I work in a RedHat environment, and maintaining a script for all OS versions became too cumbersome.
• Please fork this project to adapt it to other operating systems. I'm willing to assist with specific customization questions, but the script will focus on RHEL 7+ henceforth.
• NOTE: RHEL 6 ELS (Extended Life-cycle Support) ended 30JUNE2024. Most of health should continue to work, however, I will not make updates specifically maintain support for RHEL 6.

Recently added:

• Significant changes have been made to how the script parses information from the system.
  • I've reduced system calls by reading files directly where applicable. In practice, this should yield modest performance gains.
• Added parsing of memory/swap usage percentage. The output will resemble free -h however it will feature and additional "used%" field.
  • The field is also colored red when either memory/swap usage is greater than 90%.
• Added parsing of NTP server information.
  • Provided the target host/server is using chronyd, the NTP server status is also displayed.

If you're using RHEL 7 or later and encounter issues or have suggestions for routine error checks, please feel free to reach out!

Suggested Usage:

• To run this check once daily during the first login, you can add the following line to your .bashrc:

  [[ $(last "$USER" | awk 'NR==2{print$6}') != $(date +%-d) ]] && health
