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 FIFO Probe acquires event data from a pipe called the FIFO file. When it reads event data from the FIFO, it processes the data, one line at a time, as events. If the FIFO specified by the FifoName property does not exist, the probe will not create the FIFO file.

The probe can also be configured to recognise the beginning (header) and the end (footer) of an event. Data can be added to the header and footer of an event by setting the Header and Footer properties.

The tokens are separated according to the characters specified in the BreakCharacters property and any spaces that appear in the message section of the alarm.

The probe contains two parsers: the old parser and the new parser. The new parser differs from the old parser in the way tokens from the data stream are given element names.
