# 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 ## Optional SSL Config # ssl_ca = "/etc/telegraf/ca.pem" # ssl_cert = "/etc/telegraf/cert.pem" # ssl_key = "/etc/telegraf/key.pem" ## Use SSL 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 } ``` ### Metrics: - mongodb - tags: - hostname - fields: - active_reads (integer) - active_writes (integer) - commands_per_sec (integer) - deletes_per_sec (integer) - flushes_per_sec (integer) - getmores_per_sec (integer) - inserts_per_sec (integer) - jumbo_chunks (integer) - member_status (string) - net_in_bytes (integer) - net_out_bytes (integer) - open_connections (integer) - percent_cache_dirty (float) - percent_cache_used (float) - queries_per_sec (integer) - queued_reads (integer) - queued_writes (integer) - repl_commands_per_sec (integer) - repl_deletes_per_sec (integer) - repl_getmores_per_sec (integer) - repl_inserts_per_sec (integer) - repl_lag (integer) - repl_queries_per_sec (integer) - repl_updates_per_sec (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_per_sec (integer) - ttl_passes_per_sec (integer) - updates_per_sec (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_current_bytes (integer) - wtcache_max_bytes_configured (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) - mongodb_db_stats - tags: - db_name - hostname - fields: - avg_obj_size (float) - collections (integer) - data_size (integer) - index_size (integer) - indexes (integer) - num_extents (integer) - objects (integer) - ok (integer) - storage_size (integer) - type (string) - mongodb_shard_stats - tags: - hostname - fields: - in_use (integer) - available (integer) - created (integer) - refreshing (integer) ### Example Output: ``` mongodb,hostname=127.0.0.1:27017 active_reads=0i,active_writes=0i,commands_per_sec=6i,deletes_per_sec=0i,flushes_per_sec=0i,getmores_per_sec=1i,inserts_per_sec=0i,jumbo_chunks=0i,member_status="PRI",net_in_bytes=851i,net_out_bytes=23904i,open_connections=6i,percent_cache_dirty=0,percent_cache_used=0,queries_per_sec=2i,queued_reads=0i,queued_writes=0i,repl_commands_per_sec=0i,repl_deletes_per_sec=0i,repl_getmores_per_sec=0i,repl_inserts_per_sec=0i,repl_lag=0i,repl_queries_per_sec=0i,repl_updates_per_sec=0i,resident_megabytes=67i,state="PRIMARY",total_available=0i,total_created=0i,total_in_use=0i,total_refreshing=0i,ttl_deletes_per_sec=0i,ttl_passes_per_sec=0i,updates_per_sec=0i,vsize_megabytes=729i,wtcache_app_threads_page_read_count=4i,wtcache_app_threads_page_read_time=18i,wtcache_app_threads_page_write_count=6i,wtcache_bytes_read_into=10075i,wtcache_bytes_written_from=115711i,wtcache_current_bytes=86038i,wtcache_max_bytes_configured=1073741824i,wtcache_pages_evicted_by_app_thread=0i,wtcache_pages_queued_for_eviction=0i,wtcache_server_evicting_pages=0i,wtcache_tracked_dirty_bytes=0i,wtcache_worker_thread_evictingpages=0i 1522798796000000000 mongodb_db_stats,db_name=local,hostname=127.0.0.1:27017 avg_obj_size=818.625,collections=5i,data_size=6549i,index_size=86016i,indexes=4i,num_extents=0i,objects=8i,ok=1i,storage_size=118784i,type="db_stat" 1522799074000000000 mongodb_shard_stats,hostname=127.0.0.1:27017,in_use=3i,available=3i,created=4i,refreshing=0i 1522799074000000000 ```
