v0.20.0

[rfratto]

Release v0.20.0 of Grafana Agent is here! This is a release focused mainly on enhancing existing features and fixing bugs.

Upgrading

⚠️ THIS RELEASE HAS BREAKING CHANGES ⚠️

Read the migration guide for specific instructions on upgrading from older versions.

Notable changes:

The Grafana Agent Operator can now natively collect cAdvisor and Kubelet metrics! When the operator is spawned with a --kubelet-service flag set to <namespace>/<name>, it will maintain a Service with the provided name with one endpoint per node. This allows users to create a ServiceMonitor for getting access to the cAdvisor and Kubelet metrics. Check out our docs for a full guide.

Grafana Agent can now generate service graphs based on traces! This works by inspecting incoming spans and generating metrics. Our configuration docs for traces has more details on how you can configure and use this for yourself. Thanks to @mapno for implementing this!

Finally, thanks to @gaantunes, many of our integrations have been updated to the latest version of the upstream exporters.

As always, please read this release's CHANGELOG for the full list of features, enhancements, bugfixes, and changes.
