Data acquisition

Each probe uses a different method to acquire data. Which method the probe uses depends on the target system from which it receives data.

The IBM Tivoli Netcool/OMNIbus Probe for HTTP Server Error Log acquires event data from the Server Error Log file generated by most of the HTTP servers, including, Netscape Enterprise Servers and Apache servers. The probe connects to such a server, reads the log file specified by the LogFile property, and sends the parsed events to the ObjectServer.

On disconnection from the device, the probe stores the recovery information in the recovery file specified by the RecoveryFile property. However, the probe ignores the recovery file and reads from the beginning of the log file if the ReplayFile property is set to 1. If the CleanStart property is set to 1, the probe ignores the recovery file, but reads from the end of the log file.
