# Riak Input Plugin

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

## Configuration

```toml
# 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`)

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