Talk Title: InfluxDB at CERN and Its Experiments

The presentation gives an overview on how InfluxDB is involved in the CERN critical projects such as monitoring of accelerator systems, experiments and data centers. It goes into details of the monitoring system upgrade of one of the LHC (Large Hadron Collider) experiments – ALICE. In order to ensure high efficiecy of the experiment 2000 nodes processing data at 3.4 TB/s are constantly monitored which leads to incredible 600 kHz metric rate. These metrics are collected and aggregated by Flume and Spark and eventually stored in the InfluxDB database, which was selected in an extensive evaluation process.
