Couchbase Input Plugin

This plugin collects metrics from Couchbase, a distributed NoSQL database. Metrics are collected for each node, as well as detailed metrics for each bucket, for a given couchbase server.

⭐ Telegraf v0.12.0 🏷️ server 💻 all

Global configuration options

In addition to the plugin-specific configuration settings, plugins support additional global and plugin configuration settings. These settings are used to modify metrics, tags, and field or create aliases and configure ordering, etc. See the CONFIGURATION.md for more details.

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 specified, HTTP is used.
  ## If no port is specified, 8091 is used.
  servers = ["http://localhost:8091"]

  ## Filter bucket fields to include only here.
  # bucket_stats_included = ["quota_percent_used", "ops_per_sec", "disk_fetches", "item_count", "disk_used", "data_used", "mem_used"]

  ## Optional TLS Config
  # tls_ca = "/etc/telegraf/ca.pem"
  # tls_cert = "/etc/telegraf/cert.pem"
  # tls_key = "/etc/telegraf/key.pem"
  ## Use TLS but skip chain & host verification (defaults to false)
  ## If set to false, tls_cert and tls_key are required
  # insecure_skip_verify = false

  ## Whether to collect cluster-wide bucket statistics
  ## It is recommended to disable this in favor of node_stats
  ## to get a better view of the cluster.
  # cluster_bucket_stats = true

  ## Whether to collect bucket stats for each individual node
  # node_bucket_stats = false

  ## List of additional stats to collect, choose from:
  ##  * autofailover
  # additional_stats = []

Metrics

couchbase_node

Tags:

  • cluster: sanitized string from servers configuration field e.g.: http://user:password@couchbase-0.example.com:8091/endpoint becomes 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_autofailover

Tags:

  • cluster: sanitized string from servers configuration field e.g.: http://user:password@couchbase-0.example.com:8091/endpoint becomes http://couchbase-0.example.com:8091/endpoint

Fields:

  • count (unit: int, example: 1)
  • enabled (unit: bool, example: true)
  • max_count (unit: int, example: 2)
  • timeout (unit: int, example: 72)

couchbase_bucket and couchbase_node_bucket

Tags:

  • cluster: whatever you called it in servers in the configuration, e.g. http://couchbase-0.example.com/
  • bucket: the name of the couchbase bucket, e.g., blastro-df
  • hostname: the hostname of the node the bucket metrics were collected from, e.g. 172.16.10.187:8091 (only present in couchbase_node_bucket)

Default bucket fields:

  • quota_percent_used (unit: percent, example: 68.85424936294555)
  • ops_per_sec (unit: count, example: 5686.789686789687)
  • disk_fetches (unit: count, example: 0.0)
  • item_count (unit: count, example: 943239752.0)
  • disk_used (unit: bytes, example: 409178772321.0)
  • data_used (unit: bytes, example: 212179309111.0)
  • mem_used (unit: bytes, example: 202156957464.0)
