This page describes the basic hardware metrics collected by the Machine Agent and the additional metrics collected by the Machine Agent for Server Visibility. Not all of the metrics that appear in the Hardware Resources branch of the Metric Browser tree are provided by the Machine Agent; some are collected by the Database Agent and are used in the Database Monitoring UI, while others might be custom metrics added by another extension run by your Machine Agent.

For most metrics in the Metric Browser, you can select any point in the graph to view more information about the metric observed at that point in time. The information includes the metric identifier, date and time of the observation, along with any of the following values relevant to the metric:

• Obs (observed value): Average of all data points seen for that interval. For a cluster or a time rollup, this represents the weighted average across nodes or over time.
• Min: Minimum data point value seen for that interval.
• Max: Maximum data point value seen for that interval.
• Sum: Sum of all data point values seen for that interval. For the Percentile Metric for the App Agent for Java, this is the result of the percentile value multiplied by the Count.
• Count: Number of data points generated for the metric in that interval. The collection interval for infrastructure metrics varies by environment.
