1 System performance monitoring in the ALICE Data Acquisition System with Zabbix Adriana Telesca October 15 th, 2013 CHEP 2013, Amsterdam

2 The ALICE Data Acquisition system ALICE at the CERN LHC Data Acquisition system requirements: 4 GB/s sustained recording rate 2.5 GB/s transfer to tape 15/10/2013 Adriana Telesca, CHEP 2013 2/24

3 The ALICE Data Acquisition system For Run 2 (2015-2017): ~ 1000 nodes Readout Event building Recording Storage Support (network, PDUs) Operations For Run 3 (2019-2021): ~ 2000 nodes 15/10/2013 Adriana Telesca, CHEP 2013 3/24

4 The ALICE Data Acquisition system For Run 2 (2015-2017): ~ 1000 nodes Readout Event building Recording Storage Support (network, PDUs) Operations For Run 3 (2019-2021): ~ 2000 nodes 15/10/2013 Adriana Telesca, CHEP 2013 3/24 O2: a new combined online and offline computing for ALICE after 2018 P. Vande Vyvre’s talk today at 16:45 – Data Acquisition track

5 Lemon was used to monitor the DAQ system during Run 1 (2008-2013). Decision to replace it: Lemon future unsure Tools with additional/new functionalities LHC Long Shutdown 1 Lemon 15/10/2013 Adriana Telesca, CHEP 2013 4/24

6 ALICE DAQ monitoring system needs Low impact Extensibility/Flexibility Scalability 15/10/2013 Adriana Telesca, CHEP 2013 5/24

7 ALICE DAQ monitoring system needs Full administration GUI Easy access to data Interface with other components ORTHOS Alarming system 15/10/2013 Adriana Telesca, CHEP 2013 6/24

8 Parameters to monitor CPU Memory Disk usage Network Interfaces Processes Voltage Current Temperature Outlet status Disk status Ethernet: CPU utilization Memory utilization Cards temperature Fiber Channel: RX/TX ports rate Readout links Bytes In/Out DAQ XOFF, HLT XOFF Processes CPU and memory 15/10/2013 Adriana Telesca, CHEP 2013 7/24
