Script for monitoring a DropWizard application

Description

Simple Bash script to monitor the health check endpoints of a DropWizard application.

Usage

Making the script executable

Get the script cloning this repo or downloading it in the server where the application is running or any other Unix OS.

git clone git@github.com:rubenspg/app-monitoring.git

Make the script executable:

chmod +x healthcheck.sh

Now we are able to execute:

./healthcheck.sh

It will print this output:

$ ./healthcheck.sh
######################
Checking server health
######################

Now, the script is running and checking the health check of the application. If something goes wrong, it will print in the console and write in a log file (~/wizard_monitor.log)

Executing the script

Valid Options: [-h | -s | -p | -r]

• -h Prints the usage instructions
• -s Server DNS. Default: localhost
• -p HTTP port number of the server endpoint. Default: 8889
• -r Restart the server if it fails [true | false]. Default: tr

Note: Press [CTRL+C] to stop the script when it is running!

Examples

./healthcheck.sh -h

./healthcheck.sh -s localhost -p 8889 -r true

./healthcheck.sh -r true

Troubleshooting

Check the script's log file:

cat ~/wizard_monitor.log
