Brewing in Beats: Vsphere module in Metricbeat

By Monica Sarbu

Welcome to Brewing in Beats! With this weekly series, we're keeping you up to date with what's new in Beats, including the latest commits and releases.

Vsphere module in Metricbeat

Thanks to Amanda, Metricbeat has a new vsphere module for monitoring VMware vSphere. It uses the library Govmomi to collect metrics from any Vmware SDK URL (ESXi/VCenter). This library is built for and tested against ESXi and vCenter 5.5, 6.0 and 6.5.

Make kubernetes indexers pluggable

The libbeat processor that adds metadata by calling the Kubernetes APIs needs a way to extract the container ID from the events. The way to do that depends on the Beat. For Filebeat, for example, it’s extracted from the file path. For Metricbeat, it’s obtained based on the IP and port of the endpoint. This PR makes this step pluggable, so each Beat can provide it’s own custom implementation. This improvement is based on a community contribution from the same Vijay Samuel.

Move template loading configuration under setup

Each Beat loads the Elasticsearch mapping template at startup. The template is autogenerated from the fields.yml, that defines the mapping of each exported field. The path to the fields.yml, the name of the template and other options are defined in the Elasticsearch output configuration under outputs.elasticsearch.template.*. This pull request moves the template loading logic from the Elasticsearch output into a separate package that is configured under the setup.template.*

 
 # A template is used to set the mapping in Elasticsearch
 # By default template loading is enabled and the template is loaded.
 # These settings can be adjusted to load your own template or overwrite existing ones.
 
 # Set to false to disable template loading.
 setup.template.enabled: true
 
 # Template name. By default the template name is filebeat.
 # The version of the beat will always be appended to the given name
 # so the final name is filebeat-%{[beat.version]}.
 setup.template.name: "filebeat"
 
 # Path to fields.yml file to generate the template
 setup.template.fields: "${path.config}/fields.yml"
 
 # Overwrite existing template
 setup.template.overwrite: false

Kubernetes dashboard

With this change, the Kubelet module is renamed to kubernetes. A new sample dashboard is created and added to the list of sample Metricbeat dashboards.
