1.2. Overview of ring buffer utilities

This section will give a brief overview of some of the ring buffer utilities. Please refer to the remainder of this documentation for detailed descriptions and reference material for each utility. This list is only a selection of utilities.


This utility allows you to create, re-initialize, delete and monitor the status of ringbuffers. Normally you don't have to create ring buffers as producer frameworks will create them if they don't already exist.


Provides a simple textual formatted dump of the buffers. If you want more advanced formatting, you can use the tkdumper application. By contrast with dumper, tkdumper can be extended with plugins in such a way that it can provide a human readable formatted view of each event and the packets within the event.


Performs native mode event loggging. In this mode, event file segments consists of streams of ring buffer items. This is the default event logger run by the ReadoutShell (see below), if you want to log data in a format compatible with spectrodaq based DAQ versions (version 8.x and earlier), use eventlog-compat


Provides a GUI wrapper around a readout program that is started in a remote system.


Provides a flexible ringbuffer consumer that pipes the ring items it gets to standard output. This can be run over a pipe into your program or as the first stage of a pipeline that transforms data before providing it to an application (eventlog-compat is actually a pipeline with ringslector as the source piping through compatibilitybuffer and then on to compatibilitylogger).


Accepts data from a ring and pipes it to stdout. This is the server side of the pipeline between systems when you are setting up a proxy ring. It can also be used as the first stage of a pipeline to process data from a ring.


Provides a display of scaler event data. This application is highly configurable. It can accept an arbitrary number of scalers and format any number of pages as tabs in a notebook. Strip charts of selected scalers are also supported.


Accepts data on stdin and puts it in a ring buffer. This is the client side of the data pipeline that sets up a proxy ring.


Pipe data source for SpecTcl software that has not yet been ported to ring buffer data format. This accepts data from a ring and outputs it on stdout in nscldaq-8.x format.
