Notes

A new version of the agent has been released. Follow standard procedures to update your Infrastructure agent.

Features

• Now the Infrastructure agent, when running on Linux, can collect Docker container metrics like CPU, memory, I/O and network. This feature is enabled by default for all supported Linux OSs. Please, ensure the host meets the requirements.
• The new integration config files now support the when section. It allows you to control the execution of an integration if a given file exists. Here's an example:

integrations:
  - name: ssh-integration
    when:
      file_exists: /var/run/sshd.pid

The agent will execute ssh-integration only if the /var/run/sshd.pid file exists.

Bug fixes

• Agent service wasn't stopping / restarting properly on upstart-based Linux distributions.
• In Integration config files: Dollar symbols were unintentionally being expanded into environment variables. Before, pa$$word would have been expanded to pa${}${}word; this behavior has been corrected.
• Improved NFS support. Read and write bytes per second were not being correctly set to 0, resulting JSON marshalling errors.
