Using the Multi Cloudera Manager Status Dashboard
Use the Multi Cloudera Manager Status Dashboard Status page to monitor the CDH clusters managed by the Cloudera Manager instancess you have added to the Multi Cloudera Manager Dashboard. The Status tab displays a table with rows that contain information about each cluster. Within each row, you can click links to display additional information and go to the relevant Cloudera Manager, cluster, or service.
You configure which columns display by creating Profiles. The name of the active profile displays in a button on the right of the screen above the table of Cloudera Managers. You can choose which profile is active by clicking next to the profile name and selecting a new profile.
In a profile, you can also select Metrics, which are queries that display metrics about the functionality of each cluster. A set of metrics are provided, and you can create custom metrics using the tsquery Language.
Using the Filters section, you can limit the rows displayed by selecting various values of the displayed columns. You can define which columns are used as filters in the profile.
