Data acquisition

The probe gathers events from ZTE EMS using a 3GPP CORBA interface.

Data acquisition is further described in the following topics:

Connecting to the CORBA interface
The probe acts as an Integration Reference Point (IRP) Manager and connects to the ZTE EMS using a 3GPP CORBA interface. The probe connects to the interface using Interoperable Object Reference (IOR) files.
Retrieving alarms and notifications
If the Resynch property is set to true, the probe initially receives a list of all active alarms from the AlarmIRP point.
XML files
If the number of alarms in the ZTE EMS exceeds a maximum number (as configured in the EMS), the EMS puts all the active alarm data into an XML file. The probe then parses the XML file to retrieve the alarm data.
Persistent subscriptions
The probe can maintain a subscription to the ZTE EMS across sessions.
Timeout
The probe has a timeout facility that allows it to disconnect from the system if there has been no activity for a predefined amount of time.
Backoff strategy
If the Retry property is set to true, and the probe fails to establish a connection or loses an existing connection to the device, the probe reverts to a backoff strategy.
Filtering notifications and alarms
You can use the NotificationFilter and AlarmFilter properties to limit the alarms and notifications that the probe acquires from the ZTE EMS.
Lookup table
The probe is supplied with a lookup table that contains details of the various types of alarms that ZTE EMS generates. You might need to update the rules file to include the path to the lookup table.
Command line interface
The probe is supplied with a Command Line Interface (CLI). This interface allows you to execute commands using the probe to acknowledge alarms or request a full resynchronization.
Peer-to-peer failover functionality
The probe supports failover configurations where two probes run simultaneously. One probe acts as the master probe, sending events to the ObjectServer; the other acts as the slave probe on standby. If the master probe fails, the slave probe activates.
