zg and danielnelson Fix telegraf example arguments (#2788)
Many of the examples provided within documentation are using a single
dash for the command line arguments, but the telegraf executable
explicitly has two dashes.

There are also some inconsistencies with the ordering of the command
line argument examples.  I've ordered them so that the examples will

Riak Plugin

The Riak plugin gathers metrics from one or more riak instances.

Configuration:

# Description
[[inputs.riak]]
  # Specify a list of one or more riak http servers
  servers = ["http://localhost:8098"]

Measurements & Fields:

Riak provides one measurement named "riak", with the following fields:

  • cpu_avg1
  • cpu_avg15
  • cpu_avg5
  • memory_code
  • memory_ets
  • memory_processes
  • memory_system
  • memory_total
  • node_get_fsm_objsize_100
  • node_get_fsm_objsize_95
  • node_get_fsm_objsize_99
  • node_get_fsm_objsize_mean
  • node_get_fsm_objsize_median
  • node_get_fsm_siblings_100
  • node_get_fsm_siblings_95
  • node_get_fsm_siblings_99
  • node_get_fsm_siblings_mean
  • node_get_fsm_siblings_median
  • node_get_fsm_time_100
  • node_get_fsm_time_95
  • node_get_fsm_time_99
  • node_get_fsm_time_mean
  • node_get_fsm_time_median
  • node_gets
  • node_gets_total
  • node_put_fsm_time_100
  • node_put_fsm_time_95
  • node_put_fsm_time_99
  • node_put_fsm_time_mean
  • node_put_fsm_time_median
  • node_puts
  • node_puts_total
  • pbc_active
  • pbc_connects
  • pbc_connects_total
  • vnode_gets
  • vnode_gets_total
  • vnode_index_reads
  • vnode_index_reads_total
  • vnode_index_writes
  • vnode_index_writes_total
  • vnode_puts
  • vnode_puts_total
  • read_repairs
  • read_repairs_total

Measurements of time (such as node_get_fsm_time_mean) are measured in nanoseconds.

Tags:

All measurements have the following tags:

  • server (the host:port of the given server address, ex. 127.0.0.1:8087)
  • nodename (the internal node name received, ex. riak@127.0.0.1)

Example Output:

$ ./telegraf --config telegraf.conf --input-filter riak --test
