```
$ git clone git@github.com:ClusterCockpit/cc-metric-collector.git
$ make (downloads LIKWID, builds it as static library with 'direct' accessmode and copies all required files for the collector)
$ go get (requires at least golang 1.13)
$ go build metric-collector
$ go get (requires at least golang 1.16)
$ make tags
Available tags:

$ make # calls go build (-tags ganglia,...) -o cc-metric-collector

## `ganglia` build tag
If you want support for the [Ganglia Monitoring System](http://ganglia.info/), you have to add `-tags ganglia` to the build command line. This enables two metric sinks. One is using the command line application `gmetric` (see [`ganglia`](./sinks/gangliaSink.md) sink), the other one interacts directly with `libganglia` the main Ganglia library that is commonly installed on each compute node (see [`libganglia`](./sinks/libgangliaSink.md) sink). The later one requires configuration before building, so use `make` instead of `go build` directly.
# Running
```
$ ./metric-collector --help
$ ./cc-metric-collector --help
Usage of metric-collector:
-config string
