A data flow monitoring system for LHCb’s DAQ

This document describes the data flow monitoring tool of the DAQ system. The intended usage are to troubleshoot and find the location of problems in the DAQ. It can also be used to make an exact consistency check, i.e. to verify that the same data amounts are sent and received at the different stages....

description This document describes the data flow monitoring tool of the DAQ system. The intended usage are to troubleshoot and find the location of problems in the DAQ. It can also be used to make an exact consistency check, i.e. to verify that the same data amounts are sent and received at the different stages. Information about data amounts, current rates and different error counters are displayed for all DAQ stages from the TELL1 boards, via the event filter farm to permanent storage. In this document, the available tools and how to use it are described. The technical implementation of the monitoring system are also explained and some examples of possible future extensions are given.
