# MongoDB Input Plugin ### Configuration: ```toml [[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 ## When true, collect per collection stats # gather_col_stats = 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. ### Metrics: - mongodb - tags: - hostname - fields: - active_reads (integer) - active_writes (integer) - commands (integer) - connections_current (integer) - connections_available (integer) - connections_total_created (integer) - cursor_timed_out_count (integer) - cursor_no_timeout_count (integer) - cursor_pinned_count (integer) - cursor_total_count (integer) - deletes (integer) - document_deleted (integer) - document_inserted (integer) - document_returned (integer) - document_updated (integer) - flushes (integer) - flushes_total_time_ns (integer) - getmores (integer) - inserts (integer - jumbo_chunks (integer) - member_status (string) - net_in_bytes_count (integer) - net_out_bytes_count (integer) - open_connections (integer) - percent_cache_dirty (float) - percent_cache_used (float) - queries (integer) - queued_reads (integer) - queued_writes (integer) - repl_commands (integer) - repl_deletes (integer) - repl_getmores (integer) - repl_inserts (integer) - repl_lag (integer) - repl_queries (integer) - repl_updates (integer) - repl_oplog_window_sec (integer) - resident_megabytes (integer) - state (string) - total_available (integer) - total_created (integer) - total_in_use (integer) - total_refreshing (integer) - ttl_deletes (integer) - ttl_passes (integer) - updates (integer) - vsize_megabytes (integer) - wtcache_app_threads_page_read_count (integer) - wtcache_app_threads_page_read_time (integer) - wtcache_app_threads_page_write_count (integer) - wtcache_bytes_read_into (integer) - wtcache_bytes_written_from (integer) - wtcache_pages_read_into (integer) - wtcache_pages_requested_from (integer) - wtcache_current_bytes (integer) - wtcache_max_bytes_configured (integer) - wtcache_internal_pages_evicted (integer) - wtcache_modified_pages_evicted (integer) - wtcache_unmodified_pages_evicted (integer) - wtcache_pages_evicted_by_app_thread (integer) - wtcache_pages_queued_for_eviction (integer) - wtcache_server_evicting_pages (integer) - wtcache_tracked_dirty_bytes (integer) - wtcache_worker_thread_evictingpages (integer) - commands_per_sec (integer, deprecated in 1.10;
