gpfs collector

  "gpfs": {
    "mmpmon_path": "/path/to/mmpmon",
    "use_sudo": "true",
    "exclude_filesystem": [
      "fs1"

    "send_derived_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.

If cc-metric-collector is run as non-root, sudo can be enabled with use_sudo. Because mmpmon is by default only executable as root, the Go procedure to search for it in $PATH will fail. If you use sudo, you must specify the complete path for mmpmon using the parameter mmpmon_path.

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_opens_rate (if send_derived_values == true)
• gpfs_closes_rate (if send_derived_values == true)
• gpfs_reads_rate (if send_derived_values == true)
• gpfs_writes_rate (if send_derived_values == true)
• gpfs_readdirs_rate (if send_derived_values == true)
• gpfs_inode_updates_rate (if send_derived_values == true)
• 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_iops_rate (if send_total_values == true and send_derived_values == true)
• gpfs_metaops = gpfs_num_inode_updates + gpfs_num_closes + gpfs_num_opens + gpfs_num_readdirs (if send_total_values == true)
• gpfs_metaops_rate (if send_total_values == true and send_derived_values == true)
• gpfs_bw_read (if send_bandwidths == true)
• gpfs_bw_write (if send_bandwidths == true)
• gpfs_bw_total (if send_bandwidths == true and send_total_values == true)

The collector adds a filesystem tag to all metrics
