Simple nfsiostat collector script for the Telegraf exec input

Configuration

Sample telegraf configuration file, place in /etc/telegraf/telegraf.d/nfsiostat.conf

[[inputs.exec]]
  # Shell/commands array
  # compatible with old version
  # we can still use the old command configuration
  # command = "/usr/bin/line_protocol_collector"
  commands = ["/usr/local/bin/telegraf-execnfsiostat"]
  ## Timeout for each command to complete.
  timeout = "5s"
  # Data format to consume.
  # NOTE json only reads numerical measurements, strings and booleans are ignored.
  data_format = "influx"

Measurements & Fields:

The following fields are collected as floats under the execnfsiostat measurement. Descriptions per the manpage:

• avg_rtt - This is the duration from the time that client's kernel sends the RPC request until the time it receives the reply.
• avg_exe - This is the duration from the time that NFS client does the RPC request to its kernel until the RPC request is completed, this includes the RTT time above.
• kbop - This is the number of kB written/read per each operation.
• kbs - This is the number of kB written/read per second.
• ops_sec - This is the number of operations per second.
• retrans - This is the number of retransmissions.
• rpc_bklog - This is the length of the backlog queue.

The measurements have the following tags:

• host - the host where data was collected
• mount - the filesystem mountpoint
• option - either none (2-sec average) or all (average since mount)
