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

gpfs collector

  "ibstat": {
    "mmpmon_path": "/path/to/mmpmon",
    "exclude_filesystem": [
      "fs1"
    ],
    "send_bandwidths": true,
    "send_total_values": true
  }

The gpfs collector uses the mmpmon command to read performance metrics for GPFS / IBM Spectrum Scale filesystems.

The reported filesystems can be filtered with the exclude_filesystem option in the configuration.

The path to the mmpmon command can be configured with the mmpmon_path option in the configuration. If nothing is set, the collector searches in $PATH for mmpmon.

Metrics:

  • gpfs_bytes_read
  • gpfs_bytes_written
  • gpfs_num_opens
  • gpfs_num_closes
  • gpfs_num_reads
  • gpfs_num_writes
  • gpfs_num_readdirs
  • gpfs_num_inode_updates
  • gpfs_bytes_total = gpfs_bytes_read + gpfs_bytes_written (if send_total_values == true)
  • gpfs_iops = gpfs_num_reads + gpfs_num_writes (if send_total_values == true)
  • gpfs_metaops = gpfs_num_inode_updates + gpfs_num_closes + gpfs_num_opens + gpfs_num_readdirs (if send_total_values == true)
  • gpfs_bw_read (if send_bandwidths == true)
  • gpfs_bw_write (if send_bandwidths == true)

The collector adds a filesystem tag to all metrics
