CA Performance Center periodically synchronizes with registered data sources to send configuration information and retrieve data. The transmission ("push") phase incrementally replicates information to the data sources. Data sources receive group configuration, authentication settings, SNMP profiles, users, and roles. The information that is replicated to each database is filtered to include only items that the data source reported to CA Performance Center.
Once CA Performance Center has received data, it applies rules to associate metrics with managed items. Definitions created in CA Performance Center are sent to the data sources, but first, further changes to these definitions are prevented in the separate data source interfaces. The process of locking down data source administration is called "binding."
Global synchronization refers to the automatic reception, processing, and application of information from the data sources. Synchronization occurs every 5 minutes and includes configuration and performance data from all registered data sources. It also takes place automatically each time a new SNMP profile is added.
Synchronization status is included in the table on the Manage Data Sources page. Failures and detailed status are included in the Data Source Log.
A full synchronization occurs when a data source is first registered to CA Performance Center. It involves a full database replication. CA Performance Center receives information about all managed items in that data source. This type of synchronization does not recur automatically on an ongoing basis, but you can manually initiate it if necessary.
When you change product configuration, it can be useful to initiate a manual synchronization. This action sends new definitions to a data source immediately instead of at the next (five-minute) synchronization interval. You can select whether to do a full or incremental data source synchronization when you initiate a manual synchronization.
The Manage Data Sources page displays the status of all registered data sources. The following messages describe possible data source status conditions:
Indicates that the data source has never been contacted and is waiting for the Device Manager to poll it. The data source is polled quickly unless the Device Manager is busy performing another poll.
Indicates that data has been retrieved ("pulled") from the data source. The data source is waiting for CA Performance Center to transmit ("push") configuration information and lock corresponding administrative features ("binding").
Indicates that the data source is available for reporting. Registration has succeeded.
The Device Manager is in the process of polling the data source.
Indicates that the Device Manager is in the process of registering the data source.
Indicates that the device manager is in the process of locking the users, roles, and groups defined in the data source. Binding prevents further changes to configuration within the data source so that they match the definitions in CA Performance Center. Future modifications to these definitions are made in CA Performance Center, not in the data source.
Indicates that the device manager is in the process of synchronizing with the data source by sending or receiving configuration information.
Indicates that an unexpected failure occurred during polling. Click Log to view the Data Source Log.
Indicates that a failure occurred during synchronization. Click Log to view the Data Source Log.
A failure occurred during registration. Click Log to view the Data Source Log.
Indicates that a failure occurred during the binding of users, groups, and roles. Click Log to view the Data Source Log.
Unable to contact the data source due to communication problems.
Indicates that the versions of CA Performance Center and the data source are not compatible. Contact CA Technical Support or check CA Support Online to find supported products.
Indicates that the data source requires a software upgrade. Contact CA Technical Support.
Indicates that the data source requires registration (waiting).
Indicates that the data source requires migration (is waiting for the Device Manager).
Indicates that the data source is currently under maintenance.
Indicates that the administrator has disabled the data source.
