The BSM Component dashlet allows you to see the health of a Component, the Hosts within the Component AND the health of all of the Business Services of which the selected Component is a member:
In the example above, you can see a single Component which is operational but 'impacted' (i.e. it contains a failed Host, but not enough failed Hosts to breach the 'required online' / 'allowed to fail' thresholds). You can also see the five Hosts within the Component and their health, and also the health of the two Business Services that rely upon the Component.
The table below contains data relating to the Hosts, such as availability, status (i.e. is one of the Service Checks that is a member of the Host template used to create the Component in a state of CRITICAL), and failure duration (i.e. how long has it been failed).
The filter options for this dashlet can be seen below:
There are two configuration drawers available for filtering:
Filter by Component: Here you can choose the Component to display, and also specify which Hosts within the Component are displayed.
Filter by Status: Here you can choose to display only certain Hosts with the Component based on status, i.e. only show 'Failed' Hosts, etc.
