A metric connector creates a connection between a data source and the CA Executive Insight application. After the connection is established, the application retrieves IT metrics from the data source and publishes the metric data as business indicators to be viewed from mobile devices.
CA Executive Insight supports such data sources as CA APM, CA SOI, CA Capacity Command Center, CA Infrastructure Management, CSV files, and RESTful Web Services. To retrieve data, you add a connector and specify the connection information for the instance.
To retrieve metric data from multiple instances, you add multiple connectors.
To retrieve data for basic business indicators, a connector supporting the poll interface polls the current values of the selected IT metrics from the instance. In the case of connectors supporting the push interface, like the CSV Connector, the indicator data gets pushed when CSV files are uploaded with the connector.
The connector starts to poll for data after you add a connector and select the metrics to be used as CA Executive Insight business indicators. A new business indicator is polled and the data is aggregated approximately 2 minutes after the new business indicator is created. The data then becomes available to view on mobile devices, depending on the amount of data, polling speed, and processing time. Subsequent polling and aggregations are done at scheduled intervals, depending on the configuration characteristics of the connector.
Note: This polling and aggregation timeline applies only to "pull" type connectors. For "push" type connectors, like the CSV connector, the data is not polled, and aggregation occurs only at periodic scheduled intervals.
