birdseye

Birdseye is a Bash shell script that generates a comprehensive system report including as many details about a Linux operating environment as possible.

It focuses its reporting on the environment where programs can run: that means the Linux OS installation, hardware, storage, networking, and configuration aspects of the system.

It doesn't know about services and applications like web servers, databases, or your custom programs. But it knows about the environment where they run.

Warning

I haven't done much maintenance on Birdseye since 2015 so while it still works, it is currently fairly out of date and may not work as expected.

Recommended uses

• Generate a report about your new Linux system and explore its details via a user-friendly html page. You'll also learn the Linux programs used to generate the output, too.

• Capture a report about your important systems each time you make a change and archive the reports elsewhere. If your system needs rescuing later, having critical details available for reference can be very helpful recovery and repair actvities.

• Generate a report and attach it to bug reports for support and development teams to use. This helps avoid the back-and-forth process of them asking questions about your environment later.

Features

• Birdseye produces a single HTML file with embedded CSS formatting for easy review in a modern browser.

• Select output from some Linux diagnostic commands is included as ascii files for direct review.

• Birdeye requires only a single Bash script file that can be temporarily deployed on a Linux system. Birdseye doesn't modify your environment, deploy dependencies, or do anything else that might cause harm to your system.

Sample Report

Run as root

Warning

Birdseye runs many Linux programs to gather system details and many of these require root privileges so you have to run it as root or via sudo.

• Scary, I know!

• The source code is fully available for review so you can gain trust with it.

Instructions

• Deploy the single birdseye bash script a Linux system.

• Run the script with sudo or as root.

  sudo ./birdseye

• Answer the questions

  Birdseye will ask you a few questions. These questions are optional and you can press ENTER to use default values.

  This information is only used to populate a header on the HTML report and can be very useful in understanding the purpose of each report in a set of many.

  Answers to the following questions are used in Birdseye's HTML
  report to title and describe the system being inventoried.
  
  Providing a unique tag in the first question is highly recommended.
  
  All other questions are optional and can be skipped by hitting ENTER.
  
  
  (1/9) Provide a short tag to include with this [birdseye] ?
  ->hp-superdomex-dc-main-unit-db501
  
  (2/9) What's your name [Not specified] ?
  ->Happy User
  
  (3/9) What's your email address [Not specified] ?

  (6/9) Notes about the system hardware configuration? [Not specified]
  ->entry level config
  
  (7/9) Notes about the system software configuration? [Not specified]
  ->Baseline Linux OS, not yet configured for a workload
  
  (8/9) What is the FQDN for this systems primary NIC? [server501.db.example.com]
  ->server501.db.example.com
  
  (9/9) What is the FQDN for this systems out-of-band mgmt NIC? [null]
  ->server501-ilo.db.example.com
  

  Produces this report header:

  Birdseye System Inventory for server501.db.example.com
  
  Produced on Saturday, October 14 2023 at 21:10 by Happy User (happyuser@example.com) of Data center operations
  
  Purpose of this report: baseline for newly racked HP superdomex unit 501 in db group
  
  Hardware notes: entry level config
  
  Software notes: Baseline Linux OS, not yet configured for a workload
  
  Capture File birdseye.2023.1014.hp-superdomex-dc-main-unit-db501
  
  server501 is accessibile at server501.db.example.com with an out-of-band mgmt port at https://server501-ilo.db.example.com/
  

Configuration

Default answers to the questions birdseye asks can be defined in a .birdseye.cfg file deployed in the same directory where birdseye is run.

This will allow you to press ENTER to skip having to type your name, department and other common values while providing the answers that are unique to each Birdseye report.

See the included .birdseye.cfg or sample-dot-birdseye.cfg
