As reported on the logbook 64233, the FbmAlp latency glitches are mainly due to the data collection of the PyDAQ server .
The PyDAQ server is used to monitor the /virgoLog/, the /opt/MonitoringWeb and the /data/procdata/web directories and to provide the DAQ_DISK_FULL SER channel. The channels collected by the PyDAQ server are used mainly for monitoriing by the ServersMoni server
During the maintenance period, the following actions were performed
- the PyDAQ server is now sending its frames directly the the ServersMoni server , instead of FbmAlp previously
- the PyDAQ channels are now propagated through the Detector monitoring DAQ branch to be transmited to the FbmSt frame merger
