Example of how to monitor a playframework app with prometheus

Web application + prometheus + grafana

Example of how to monitor an application using:

• the prometheus client lib
• prometheus
• alermanager
• grafana
• cAdvisor

Prerequisites

To run everything you just need docker-compose.

How do I starting playing?

Before running this command be aware that the docker files are quite heavy, so this could take a while

docker-compose up -d

More information

I wrote several implementation using different frameworks. Feel free to used the one that suites you more.

I wrote some blog articles covering prometheus and monitoring:

• The first one covers basic concepts and terminology.

• The second one handles mostly alerting.

play-prometheus's Issues

Code for the Play application

Great work!

Can I find the source code for the play application somewhere? I am just starting to learn Play and Scala, and I don't have any success in putting together the pieces based on the instructions in the pdf, so I must be missing something.

Running the whole thing via docker-compose works like a charm, but I can't get something similar to work in my own toy Play app.

Any help is highly appreciated.

change the kamon akka-http example to use a directive

kamon-io could be a really good example!
