Monitoring

In this recipe, we will set up monitoring for Mesos.

Getting ready

We must have a running monitoring ecosystem. Metrics storage could be a simple time-series database such as graphite, influxdb, or prometheus. In the following example, we are using graphite and our metrics are published with http://diamond.readthedocs.io/en/latest/.

How to do it...

Monitoring is enabled by default. Mesos does not provide any way to automatically push metrics to the registry. However, it exposes them as a JSON that can be periodically pulled and saved into the metrics registry:

1. Install Diamond using following command:

pip install diamond

2. If additional packages are required to install them, run:

sudo apt-get install python-pip python-dev build-essential.

Note

pip (Pip Installs Packages) is a Python package manager used to install software written in Python.

3. Configure the metrics handler and interval. Open /etc/diamond/diamond.conf and ensure that there is a section for graphite configuration:
