README

MongoDB Input Plugin

All MongoDB server versions from 2.6 and higher are supported.

Configuration

[[inputs.mongodb]]
  ## An array of URLs of the form:
  ##   "mongodb://" [user ":" pass "@"] host [ ":" port]
  ## For example:
  ##   mongodb://user:auth_key@10.10.3.30:27017,
  ##   mongodb://10.10.3.33:18832,
  servers = ["mongodb://127.0.0.1:27017?connect=direct"]  

  ## When true, collect cluster status.
  ## Note that the query that counts jumbo chunks triggers a COLLSCAN, which
  ## may have an impact on performance.
  # gather_cluster_status = true

  ## When true, collect per database stats
  # gather_perdb_stats = false

  ## When true, collect per collection stats
  # gather_col_stats = false
  
  ## When true, collect usage statistics for each collection
  ## (insert, update, queries, remove, getmore, commands etc...).
  # gather_top_stat = false

  ## List of db where collections stats are collected
  ## If empty, all db are concerned
  # col_stats_dbs = ["local"]

  ## 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
  # insecure_skip_verify = false
Permissions

If your MongoDB instance has access control enabled you will need to connect as a user with sufficient rights.

With MongoDB 3.4 and higher, the clusterMonitor role can be used. In version 3.2 you may also need these additional permissions:

> db.grantRolesToUser("user", [{role: "read", actions: "find", db: "local"}])

If the user is missing required privileges you may see an error in the Telegraf logs similar to:

Error in input [mongodb]: not authorized on admin to execute command { serverStatus: 1, recordStats: 0 }

Some permission related errors are logged at debug level, you can check these messages by setting debug = true in the agent section of the configuration or by running Telegraf with the --debug argument.
