MongoDB Output Plugin

This plugin writes metrics to MongoDB automatically creating collections as time series collections if they don't exist.

[!NOTE] This plugin requires MongoDB v5 or later for time series collections.

⭐ Telegraf v1.21.0 🏷️ datastore 💻 all

Global configuration options

Plugins support additional global and plugin configuration settings for tasks such as modifying metrics, tags, and fields, creating aliases, and configuring plugin ordering. See CONFIGURATION.md for more details.

Configuration

toml

# A plugin that can transmit logs to mongodb
[[outputs.mongodb]]
  ## Connection string
  ## example: dsn = "mongodb://mongod1:27017,mongod2:27017,mongod3:27017/admin&replicaSet=myReplSet&w=1"
  dsn = "mongodb://localhost:27017"

  ## Overrides serverSelectionTimeoutMS in DSN if set
  # timeout = "30s"

  ## Authentication method, available options are NONE, PLAIN, SCRAM, X509
  # authentication = "NONE"

  # ## for SCRAM-SHA-256 authentication
  # # authentication = "SCRAM"
  # # username = "root"
  # # password = "***"

  # ## for PLAIN authentication (e.g., LDAP)
  # ## IMPORTANT: PLAIN authentication sends credentials in plaintext during the
  # ## authentication handshake. Always use TLS to encrypt credentials in transit.
  # # authentication = "PLAIN"
  # # username = "myuser"
  # # password = "***"

  # ## X509 based certificate authentication
  # # authentication = "X509"
  # # tls_ca = "ca.pem"
  # # tls_key = "client.pem"
  # # # tls_key_pwd = "changeme" # required for encrypted tls_key
  # # insecure_skip_verify = false

  ## Database to store measurements and time series collections
  # database = "telegraf"

  ## Granularity can be seconds, minutes, or hours.
  ## Configuring this value will be based on your input collection frequency
  ## see https://docs.mongodb.com/manual/core/timeseries-collections/#create-a-time-series-collection
  # granularity = "seconds"

  ## TTL to automatically expire documents from the measurement collections.
  # ttl = "360h"

  ## If true, write multiple metrics for the same collection in a batched
  ## fashion. Otherwise, write each metric individually.
  # write_batch = false
