|MOBL04||Karabo Data Logging: InfluxDB Backend and Grafana UI||56|
The photon beam lines and instruments at the European XFEL (EuXFEL) are operated using the Karabo* control system that has been developed in house since 2011. Monitoring and incident analysis requires quick access to historic values of control data. While Karabo’s original custom-built text-file-based data logging system suits well for small systems, a time series data base offers in general a faster data access, as well as advanced data filtering, aggregation and reduction options. EuXFEL has chosen InfluxDB** as backend that is operated since summer 2020. Historic data can be displayed as before via the Karabo GUI or now also via the powerful Grafana*** web interface. The latter is e.g. used heavily in the new Data Operation Center of the EuXFEL. This contribution describes the InfluxDB setup, its transparent integration into Karabo and the experiences gained since it is in operation.
