A Cloudera Manager component that has metrics associated with it, such as a service,
role, role type, or host.
Metric
A property that can be measured to quantify the state of an entity
or activity, such as the number of open file descriptors or CPU utilization percentage.
Time series
A list of (time, value) pairs that is associated with some (entity,
metric) pair. For example, (datanode-1,
fd_open), (hostname, cpu_percent). In more
complex cases, the time series can represent operations on other time series. For example,
(datanode-1 , cpu_user + cpu_system).
Facet
A display grouping of the dataset, shown in separate charts. By default, when a query
returns multiple time series, they are displayed in individual charts. Facets allow you to
display the time series in separate charts, in a single chart, or grouped by various
attributes of the set of time series.
