Telegraf Plugin: Couchbase

Configuration:

# Read per-node and per-bucket metrics from Couchbase
[[inputs.couchbase]]
  ## specify servers via a url matching:
  ##  [protocol://][:password]@address[:port]
  ##  e.g.
  ##    http://couchbase-0.example.com/
  ##    http://admin:secret@couchbase-0.example.com:8091/
  ##
  ## If no servers are specified, then localhost is used as the host.
  ## If no protocol is specifed, HTTP is used.
  ## If no port is specified, 8091 is used.
  servers = ["http://localhost:8091"]

Measurements:

couchbase_node

Tags:

  • cluster: sanitized string from servers configuration field e.g.: http://user:password@couchbase-0.example.com:8091/endpoint -> http://couchbase-0.example.com:8091/endpoint
  • hostname: Couchbase's name for the node and port, e.g., 172.16.10.187:8091

Fields:

  • memory_free (unit: bytes, example: 23181365248.0)
  • memory_total (unit: bytes, example: 64424656896.0)

couchbase_bucket

Tags:

  • cluster: whatever you called it in servers in the configuration, e.g.: http://couchbase-0.example.com/)
