Simple Bash script to generate a static status page. Displays the status of websites, services (HTTP, SAP, MySQL...), and ping. Everything is easy to customize. 🤓
You can also easily check more complicated things with this script.For example, if a text is present on a web page or if a host appears in the route path (traceroute).Checking the route path is useful, for instance, if you have a backup mobile internet connection in addition to your cable connection.
In addition to the status web page, there is also a JSON version and an SVG icon.With the scriptalert.sh, you can be alerted by email, SMS or Pushover in case of a downtime.
By default, it's a good practice to create astatus directory within your home directory and place everything in it :
mkdir~/statuscd~/status
Download Bash scriptstatus.sh:
curl -O"https://raw.githubusercontent.com/Cyclenerd/static_status/master/status.sh"💡 Tip: Update works exactly the same way as the installation. Simply download the latest version of
status.sh.
Download configuration filestatus_hostname_list.txt:
curl -O"https://raw.githubusercontent.com/Cyclenerd/static_status/master/status_hostname_list.txt"Customize thestatus_hostname_list.txt configuration file and define what you want to monitor:
vi status_hostname_list.txt
Edit the scriptstatus.sh, or better add more configuration to the configuration fileconfig.
Download the example configuration file:
curl \ -f"https://raw.githubusercontent.com/Cyclenerd/static_status/master/config-example" \ -o"config"
Customize the configuration file:
vi config
bash status.sh
Usage: status.sh [OPTION]:OPTION is one of the following: silent no output from faulty connections to stout (default: no) loud output from successful and faulty connections to stout (default: no) debug displays all variables help displays help (this message)Example:
bash status.sh loud
Execute a cron job every minute:
crontab -e
Add:
*/1 * * * * bash "/path/to/status.sh" silent >> /dev/nullOnlybash,coreutilscurl,grep,nc,ping,sed andtraceroute.In many *NIX distributions (Ubuntu, macOS) the commands are already included.If not, the missing packages can be installed quickly.
On a debian-based system (Ubuntu), just run:
sudo apt install \ coreutils \ curl \ grep \ iputils-ping \ netcat-openbsd \ sed \ traceroute
💡 Tip: You can disable the
traceroutedependency. AddMY_TRACEROUTE_HOST=''to your config.
Thisdemo page is generated withGitHub Action:https://cyclenerd.github.io/static_status/
You can display a custom text instead of the HOSTNAME/IP/URL (see example below).
status_hostname_list.txt:
ping;8.8.8.8|Google DNSnc;8.8.8.8|DNS @ Google;53curl;http://www.heise.de/ping|www.heise.detraceroute;192.168.211.1|DSL Internet;3script;/bin/true|always upYou can also create a JSON status page.Configure the variableMY_STATUS_JSON with the location where the JSON file should be stored.
Example JSON:
[ {"site":"https://www.nkn-it.de/gibtesnicht","command":"curl","status":"Fail","time_sec":"282","updated":"2023-04-19 14:01:23 UTC" }, {"site":"https://www.heise.de/ping","command":"curl","status":"OK","time_sec":"0","updated":"2023-04-19 14:01:23 UTC" }]If you want to signal directly if everything is fine or if something is wrong in the infrastructure, you can insert the SVG icon into your website.
Please remember to include the image with a cache breaker URL (eg. an appended timestamp:
<ahref="status.html">Status<imgsrc="status.svg?{{ timestamp }}"></a>
Static websites need to fallback to render the icon with javascript, eg with:
document.write('<imgsrc="status.svg?' + Date.now() + '">')You can extend the checks ofstatus.sh with your own custom shell scripts.
If the shell script outputs a return code0 it is evaluated as available.With the special return code80, it is not classified as down but as degraded.With all other return codes, it is a failure (outage, down).
Add your script to thestatus_hostname_list.txt configuration file. Example:
script;script.shscript;/path/to/your/script.sh|Custom Textscript;/path/to/your/script.sh parameterA parameterB|Custom TextThe scriptcheck-websites.sh is an example.
Bug Fixes and Enhancements: Address any reported issues and consider adding new features to improve the script's functionality.
Comprehensive Documentation: Create detailed documentation covering script configuration, customization, and advanced usage.
Code Cleanup: Enhance code readability and performance for better maintainability.
Security: Review and enhance security measures to protect against vulnerabilities.
