Reading Time: 3 minutes In our previous blog post, How to audit DC/OS Services?, we learned how to locally audit service/app in DC/OS via dcos-adminrouter.service. This blog is in continuation of the previous one and here we will explore how we can audit DC/OS Service via Prometheus /Filebeat. Quick Recap We have seen that DC/OS doesn’t provides any web interface is to track the change in service/app configs , Continue Reading
Reading Time: 4 minutes DC/OS is a distributed systems kernel that lets you manage multiple machines as if they were a single computer.

Slack notification channel: First, open the URL http://localhost:3000 in the browser and log in to the Continue Reading

In this solution, we used jmx2graphite as a metrics exporter which takes the metrics from the Jolokia URL where Jolokia exposes the JMX metrics and pushes those metrics to Graphite. But, there is a problem with this solution that we need to deploy one jmx2graphite per service. So Continue Reading

We looked for the solution and reached to the conclusion which we will discuss in this blog. I will try to explain each and every component of the solution along with the setup and the integration part of the whole system. Proposed solution: Service (application) exposes Continue Reading
