MongoDB Input Plugin

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"]

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

  ## 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 }
