O2 Monitoring library
|
DPL stands for Data Processing Layer and it is part of ALICE O2 Framework.
A URL to the monitoring backend can be passed through monitoring-backend
parameter. This will redirect all the metric to the selected backend. The list of supported backends is available in the Monitoring README file.
Then, from the DataProcessingDevice
source Monitoring instance can be accessed via Monitoring service.
There are so-called Community Services available at CERN GPN network and O2 developers are welcome to use them in order to store and display metrics.
A time-series database, called InfluxDB, is used for metric storage.
Pass the following Monitoring URL via --monitoring-backend
to your workflow in order to redirect metrics to Community Services instance:
Time-series can be visualised in Grafana using a web browser.
