The Enterprise Common Collector no longer has a session with the data source, and inventory and metrics data are no longer being collected.
The Interval End Time attribute in a number of Tivoli® Enterprise Portal workspaces displays NOT COLLECTED instead of the expected interval date and time information. The data source configuration indicates that the status is disconnected, and the enabled parameter is set to false, even though no administrator set enabled to false.
One of the components that performs some aspect of the data source monitoring encountered an unexpected error. In response to this situation, the collector stopped all components associated with the monitoring of this data source and ended the session with the data source.
If the unexpected error is related to a connection or session problem, or some other potentially temporary problem, a new session is automatically established and monitoring is resumed. But if collector does not recognize the error and cannot recover automatically, the data source was disabled. This action keeps the collector from generating the same error over and over each time a new session is established, thus preventing thrashing.

Reenable the data source using the data-sources update command (see Setting up HMC data sources by using the command-line). If the problem occurs again, search IBM® support for a a technote regarding the problem. If nothing is available, contact IBM Software Support.
