Telegraf plugin: MongoDB

Configuration

[[inputs.mongodb]]
  ## An array of URI to gather stats about. Specify an ip or hostname
  ## with optional port add password. ie,
  ##   mongodb://user:auth_key@10.10.3.30:27017,
  ##   mongodb://10.10.3.33:18832,
  ##   10.0.0.1:10000, etc.
  servers = ["127.0.0.1:27017"]
  gather_perdb_stats = false

For authenticated mongodb istances use connection mongdb connection URI

[[inputs.mongodb]]
  servers = ["mongodb://username:password@10.XX.XX.XX:27101/mydatabase?authSource=admin"]

This connection uri may be different based on your environement and mongodb setup. If the user doesn't have the required privilege to execute serverStatus command the you will get this error on telegraf

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

Description

The telegraf plugin collects mongodb stats exposed by serverStatus and few more and create a single measurement containing values e.g.

  • active_reads
  • active_writes
  • commands_per_sec
  • deletes_per_sec
  • flushes_per_sec
  • getmores_per_sec
  • inserts_per_sec
  • net_in_bytes
  • net_out_bytes
  • open_connections
  • percent_cache_dirty
  • percent_cache_used
  • queries_per_sec
  • queued_reads
  • queued_writes
  • resident_megabytes
  • updates_per_sec
  • vsize_megabytes
  • ttl_deletes_per_sec
  • ttl_passes_per_sec
  • repl_lag
  • jumbo_chunks (only if mongos or mongo config)

If gather_db_stats is set to true, it will also collect per database stats exposed by db.stats() creating another measurement called mongodb_db_stats and containing values:

  • collections
  • objects
  • avg_obj_size
  • data_size
  • storage_size
  • num_extents
  • indexes
  • index_size
  • ok
