Riak Input 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:

$ ./circonus-unified-agent --config circonus-unified-agent.conf --input-filter riak --test
