This application checks Magnificent service frequently - at least several times a minute. It indicates how healthy the Magnificent service has been, over the last little while. It can also tell our system administrator if Magnificent has not been responding at all.

System administrator can see the result of monitoring in the next file: ./log/magnificent.log Application writes one log entry per each health check with the appropriate log level (Healthy: INFO, Unhealthy: WARN, Unavailable: ERROR).

You can build this application using the next command:

mvn clean package

As a result of the program execution, an executable jar will be generated:

target/magnificent-service-monitor-VERSION-jar-with-dependencies.jar

You can run this application using the next command:

java -jar magnificent-service-monitor-1.0-SNAPSHOT-jar-with-dependencies.jar

Or from your favourite IDE (just start main method from the code.codechallenge.Main class).

The user is able to configure the service under monitoring (below you can see configuration properties and default values). monitoring.server.schedule.fixed.rate - This property is used to configure how frequently health check should be performed. monitoring.server.connection.timeout - This property is used to configure default connection timeout to the server.

monitoring.server.url=http://localhost monitoring.server.port=12345 monitoring.server.schedule.fixed.rate=10000 monitoring.server.connection.timeout=5000

Install Python. Python2 and Python3 both work. pip install twisted python server.py Okay, now you're running magnificent! Visit http://localhost:12345 in a web browser or something. It should throw a verbose error, or return "Magnificent!".
