cc-metric-collector-v0.1

First version of the ClusterCockpit metric collector, a node agent to read data from different sources, process them and send them to a set of sinks.

The collector currently contains collectors for:

• CPU (OS statistics and hardware performance event measurements)
• Memory
• Disk
• Filesystems like NFS, Lustre or GPFS
• Network (Ethernet and InfiniBand)
• Nvidia GPUs

Metrics can be sent to one or more sinks:

• InfluxDB
• HTTP-based storage engines like the ClusterCockpit Metric Store
• Ganglia Monitoring System
• NATS

If you want to create a tree of metric collectors, you can receive data through an NATS based receiver and forward them to the sinks.
