Monitoring deployed nodes
Monitoring your nodes
Grid'5000 provides different services to monitor your nodes during your experiment: Kwapi/Kwollect and Ganglia.
Ganglia uses a service running on the nodes to collect informations.
Electrical power consumption monitoring is available on some Grid'5000 clusters using Kwapi and Kwollect.
Nodes metrics collection: Ganglia
If you point your browser to https://intranet.grid5000.fr/ganglia/, you will see all the metrics collected on Grid'5000. If you navigate first to the site, then to the node you have reserved, you will see the metrics collected for one node.
To limit experiment artefacts to the minimum, monitoring is not activated by default on reference environments. On a *-min image, you will first need to install the ganglia-monitor package :
You need to start the ganglia-monitor service to get meaningful results from the metrology API. You can do this using the following:
Energy consumption : Kwapi and Kwollect
It does not require any specific application running on the nodes. Go to the Kwapi page of Lyon, and visualize the power consumption of nodes you reserved (you might need to switch to another site using the Other sites menu).
The raw values and the historical data for both monitoring systems is also available through the Grid'5000 API.
