Kubernetes check

The Kubernetes check retrieves metrics from cAdvisor running under Kubelet.

See #2031

OpenStack check

The OpenStack check is intended to run besides individual hypervisors. It can be scoped to any set of projects living on that host via instance-level config.

At the hypervisor-level it collects:

• Hypervisor Uptime and Statistics

At the project-level it collects:

• Diagnostics for guest servers within that project
• Absolute limits for the project

Additionally it sends service checks to register the UP/DOWN state of networks discovered by the agent,
the locally running hypervisor, and the outward-facing (public || internal) API services of Nova, Neutron and Keystone

Authentication

While the check will run without issues as an admin user, it is recommended to configure a read-only datadog user and configure the check with the corresponding user/password. Instructions on setting up the datadog user + role , as well as the changes required to the policy.json file can be found here

A note on compatibility

Authentication is performed via the password method, and requires Identity API v3
Nova API v2 and v2.1 are supported, with minor additional configuration necessary for v2.

A big thank you @mtougeron !

See #1864

New WMI module wrapper

Datadog Agent 5.6.0 ships a new built-in lightweight Python WMI module wrapper, built on top of pywin32 and win32com extensions.

Specifications

• Based on top of the pywin32 and win32com third party extensions only
• Compatible with Raw* and Formatted Performance Data classes
  • Dynamically resolve properties' counter types
  • Hold the previous/current Raw samples to compute/format new values*
• Fast and lightweight
  • Avoid queries overhead
  • Cache connections and qualifiers
  • Use wbemFlagForwardOnly flag to improve enumeration/memory performance

__ Raw data formatting relies on the avaibility of the corresponding calculator.
Please refer to checks.lib.wmi.counter_type for more information*

Usage

The new WMI module wrapper is used among the following checks to improve speed performances:

• System
• WMI

Other checks relying on WMI collection will follow in future versions of Datadog Agent.

See #2011

[Warning] JMXFetch false-positive bean match & potential backward incompatibilities issues

JMXFetch was illegitimately matching some MBeans attributes when the associated MBean had one of its parameter defined in an instance configuration.

The issue is addressed. As a result, please note that metrics related to false positive bean matches are not reported anymore.

Potential affected checks: ActiveMQ, Cassandra, JMX, Solr, Tomcat.

For more information, please get in touch with support@datadoghq.com
