Machine Agent Metric Collection

The Machine Agent collects hardware metrics using default extensions appropriate to specific operating systems. The following table lists the metric collection extension and its supported OS information. In some limited cases, you may want to change the default collection extension. The table also lists the most common reasons for changing the default extension.

Supported environments, observation rates, configurability, some metric names, and definitions depend on the extension.

Note: In case of a time discrepancy issue on a server (not related to daylight savings time), where time is reset manually, the Machine Agent stops reporting. During this interruption, application and server data are not reported. To continue monitoring, you must restart the Machine Agent.
