Merge develop branch into main (#106) 
* Add cpu_used (all-cpu_idle) to CpustatCollector

* Update to line-protocol/v2

* Update runonce.yml with Golang 1.20

* Update fsnotify in LIKWID Collector

* Use not a pointer to line-protocol.Encoder

* Simplify Makefile

* Use only as many arguments as required

* Allow sum function to handle non float types

* Allow values to be a slice of type float64, float32, int, int64, int32, bool

* Use generic function to simplify code

* Add missing case for type []int32

* Use generic function to compute minimum

* Use generic function to compute maximum

* Use generic function to compute average

* Add error value to sumAnyType

* Use generic function to compute median

* For older versions of go slices is not part of the installation

* Remove old entries from go.sum

* Use simpler sort function

* Compute metrics ib_total and ib_total_pkts

* Add aggregated metrics.
Add missing units

* Update likwidMetric.go

Fixes a potential bug when `fsnotify.NewWatcher()` fails with an error

* Completly avoid memory allocations in infinibandMetric read()

* Fixed initialization: Initalization and measurements should run in the same thread

cpustat collector

  "cpustat": {
    "exclude_metrics": [
      "cpu_idle"
    ]
  }

The cpustat collector reads data from /proc/stat and outputs a handful node and hwthread metrics. If a metric is not required, it can be excluded from forwarding it to the sink.

Metrics:

  • cpu_user
  • cpu_nice
  • cpu_system
  • cpu_idle
  • cpu_iowait
  • cpu_irq
  • cpu_softirq
  • cpu_steal
  • cpu_guest
  • cpu_guest_nice
  • cpu_used = cpu_* - cpu_idle
