|Host||Host of the Storm UI service|
|Port||Port of the Storm UI service|
|Username||Username to access the Storm UI service|
|Password||Password to access the Storm UI service|
|Topologies Filter||Select topologies (by name or id) to show metrics for. If not set, it will shows all topologies|
|Show Bolts||Show metrics for each bolt in each topology (default: true)|
|Show Spouts||Show metrics for each spout in each topology (default: true)|
|Source||The Source to display in the legend for the metrics data. It will default to the hostname of the server|
|Poll Interval||How often should the plugin poll for metrics|
An Event will be generated whenever the value of lasterror is not nil and will be displayed in the situation room. Once an error occurs an event will be triggered during each polling interval. We will see only one Event for the same error in the situation room with an occurrence count. A new Event will be generated for a different error.
