## `gpfs` collector
```json
"ibstat": {
"mmpmon_path": "/path/to/mmpmon",
"exclude_filesystem": [
"fs1"
]
}
```
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.
Metrics:
* `bytes_read`
* `gpfs_bytes_written`
* `gpfs_num_opens`
* `gpfs_num_closes`
* `gpfs_num_reads`
* `gpfs_num_readdirs`
* `gpfs_num_inode_updates`
The collector adds a `filesystem` tag to all metrics

The `ibstat` collector reads either data through the `perfquery` command or the sysfs files below `/sys/class/infiniband/<device>`.
The `ibstat` collector includes all Infiniband devices that can be

The devices can be filtered with the `exclude_devices` option in the configuration.

* `ib_xmit`
* `ib_recv_pkts`
* `ib_xmit_pkts`
The collector adds a `device` tag to all metrics
