The Monitoring Infrastructure is a component of the European Project TANGO (http://tango-project.eu ).
Relation to other TANGO components
The responsibility of this component is twofold. On one side it must provide running applications with metrics of the status of different devices, such as CPU, GPUs, FPGAs, etc. This information should be both energy consumption and performance status. On the other side it should also provide historical statistics for device metrics for latter analysis of upper components of the TANGO architecture.
This component relies on Collectd, which will be used together with some custom plugins done specifically for TANGO, in order to get and store energy consumption and performance values from the applications running in the different environments.
Available collection of probes to measure energy in heterogeneous hardware for the TANGO project:
-
- power
- temperature
- memory used
- usage
- processes running

The monitoring Infrastructure is composed by the following components:
Collectd is a daemon which collects system and application performance metrics periodically and provides mechanisms to store the values in a variety of ways. The TANGO Collectd plugins provide metrics from specific devices like the NVIDIA GPUs and the XEON PHI processors. The metrics gathered from this component are stored in the InfluxDB instance.
InfluxDB is used as a data store for the metrics gathered from Collectd. The REST API and the Graphana applications connect to this tool in order to present the processed information.
Graphana is a data visualization and monitoring tool with support for Graphite, InfluxDB and many more databases. This component is used as the GUI of the monitoring component.
The main purpose of the REST API application is to offer to other TANGO components the information they need from the metrics gathered from Collectd.
