## `BeeGFS on Demand` collector
This Collector is to collect BeeGFS on Demand (BeeOND) metadata clientstats.

```json
  "beegfs_meta": {
	"beegfs_path": "/usr/bin/beegfs-ctl",
    "exclude_filesystem": [
      "/mnt/ignore_me"
    ],
    "exclude_metrics": [     
          "ack",
          "entInf",
          "fndOwn"
  }
```

The `BeeGFS On Demand (BeeOND)` collector uses the `beegfs-ctl` command to read performance metrics for
BeeGFS filesystems.

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

The path to the `beegfs-ctl` command can be configured with the `beegfs_path` option
in the configuration.

When using the `exclude_metrics` option, the excluded metrics are summed as `other`.

Available Metrics:

* sum
* ack
* close
* entInf
* fndOwn
* mkdir
* create
* rddir
* refrEnt
* mdsInf
* rmdir
* rmLnk
* mvDirIns
* mvFiIns
* open
* ren
* sChDrct
* sAttr
* sDirPat
* stat
* statfs
* trunc
* symlnk
* unlnk
* lookLI
* statLI
* revalLI
* openLI
* createLI
* hardlnk
* flckAp
* flckEn
* flckRg
* dirparent
* listXA
* getXA
* rmXA
* setXA
* mirror

The collector adds a `filesystem` tag to all metrics
