Apache Mesos Cookbook

By: David Blomquist, Tomasz Janiszewski

Overview of this book

Apache Mesos is open source cluster sharing and management software. Deploying and managing scalable applications in large-scale clustered environments can be difficult, but Apache Mesos makes it easier with efficient resource isolation and sharing across application frameworks. The goal of this book is to guide you through the practical implementation of the Mesos core along with a number of Mesos supported frameworks. You will begin by installing Mesos and then learn how to configure clusters and maintain them. You will also see how to deploy a cluster in a production environment with high availability using Zookeeper. Next, you will get to grips with using Mesos, Marathon, and Docker to build and deploy a PaaS. You will see how to schedule jobs with Chronos. We’ll demonstrate how to integrate Mesos with big data frameworks such as Spark, Hadoop, and Storm. Practical solutions backed with clear examples will also show you how to deploy elastic big data jobs. You will find out how to deploy a scalable continuous integration and delivery system on Mesos with Jenkins. Finally, you will configure and deploy a highly scalable distributed search engine with ElasticSearch. Throughout the course of this book, you will get to know tips and tricks along with best practices to follow when working with Mesos.

Monitoring Metronome

In this recipe, you will learn how to collect logs and metrics from Metronome.

How to do it...

By default, Metronome writes logs to stdout. Logs are managed by logback.conf, where we can define our custom appender, change what is logged, and change log patterns.

For example, we can extend the stacktrace size from the default 10 to 20 lines. To do this, open /opt/mesosphere/metronome-0.1.9/conf/logback.conf, find the STDOUT appender, and change the following code:

<pattern>%coloredLevel %logger{15} - 

Change it to the following code:

<pattern>%coloredLevel %logger{15} - 

before level information to datetime in log.

Now after the service Metronome restart, you can view your logs with:

sudo journalctl -f -u metronome

Unfortunately, Metronome does not provide bindings for external monitoring services such as Logstash, Graphite, or Datadog. Logs must be aggregated and parsed by other tools...
