The CERN IT Department is completing the re-engineering of the monitoring and alarms infrastructure for the IT Data Centres and for the WLCG Grid Infrastructure. Therefore, the monitoring team is designing, developing and deploying the unified monitoring and alarms infrastructure that is progressively replacing the IT and WLCG specific solutions. This unified monitoring covers all phases of the dataflow such as collecting metrics and logs, live online data streaming, large-scale analytics and comprehensive alarms.

As a Computing Engineer in the IT-CM Group, you will contribute to the development, operations of the CERN unified monitoring and alarms infrastructure across a wide range of platforms and technologies needed to stream, analyse and store metrics collected, with a frequency of 80k metrics/sec, from:
  • The CERN Data Centres compute and storage resources (e.g. 35k VMs, > 8k hosts);
  • The WLCG world-wide activities for data transfers, jobs execution and resources availability on more than 300 grid sites.

The unified monitoring infrastructure is fully deployed and managed at CERN by the Monitoring team and is based on established open source technologies, such as Collectd, Kafka, Spark, ElasticSearch, HDFS, InfluxDB and Grafana.

Your main activities will consist of:
  • Key contribution in the development and improvement of the monitoring service.
  • Operation and support of the monitoring infrastructure service.
  • User support on monitoring for other IT services and joining the regular support rota for IT Data Centres and WLCG Grid users.
  • Advice and solution design to IT service managers and LHC experiments staff on the use of the unified monitoring infrastructure and of the monitoring data.
  • Management of the monitoring services which includes third level service user support, deployment of software packages, operation of the service with verification of performance and security.
  • Automation using Agile/DevOps tools such as Puppet to support monitoring within the standard CERN IT procedures.
  • Collaboration in the CERN IT change management procedures.
  • Definition, documentation and implementation of procedures following the standards of the IT Department.
  • Close collaboration with other IT groups, departments and physics experiments at CERN.
  • Interaction and contribution to Open Source communities such and Grafana and Collectd.
