Marathon is a container orchestration platform for the Mesosphere Datacenter Operating System (DC/OS) and Apache Mesos. This integration installs and configures Telegraf to send Marathon metrics into Wavefront. Telegraf is a light-weight server process capable of collecting, processing, aggregating, and sending metrics to a Wavefront proxy.
In addition to setting up the metrics flow, this integration also installs a dashboard. Here are the Overview and Task Processing sections of a dashboard displaying Mesos cluster metrics:
To see a list of the metrics for this integration, select the integration from https://github.com/influxdata/telegraf/tree/master/plugins/inputs.
Step 1. Install the Telegraf Agent
This integration uses the HTTP input plugin for Telegraf to extract metrics from Marathon.
Log in to your Wavefront instance and follow the instructions in the Setup tab to install Telegraf and a Wavefront proxy in your environment. If a proxy is already running in your environment, you can select that proxy and the Telegraf install command connects with that proxy. Sign up for a free trial to check it out!
Step 2. Enable the HTTP input plugin
marathon.conf file in
/etc/telegraf/telegraf.d and add the following snippet:
[[inputs.http]] ## One or more URLs from which to read formatted metrics urls = [ "http://<mesos_leader_ip>:8080/metrics", "http://<mesos_leader_ip>:8080/v2/tasks", "http://<mesos_leader_ip>:8080/v2/queue", "http://<mesos_leader_ip>:8080/v2/deployments", ] data_format = "json" name_prefix = "marathon."
Step 3. Restart Telegraf
sudo service telegraf restart to restart your Telegraf agent.
