Netdata will use the first available to send the metrics. | localhost | yes | +| username | Username for HTTP authentication | my_username | no | +| password | Password for HTTP authentication | my_password | no | +| data source | Selects the kind of data that will be sent to the external database. (as collected/average/sum) | | no | +| hostname | The hostname to be used for sending data to the external database server. | [global].hostname | no | +| prefix | The prefix to add to all metrics. | Netdata | no | +| update every | Frequency of sending sending data to the external database, in seconds. | 10 | no | +| buffer on failures | The number of iterations (`update every` seconds) to buffer data, when the external database server is not available. | 10 | no | +| timeout ms | The timeout in milliseconds to wait for the external database server to process the data. | 2 * update_every * 1000 | no | +| send hosts matching | Hosts filter. Determines which hosts will be sent to the external database. The syntax is [simple patterns](https://github.com/netdata/netdata/tree/master/libnetdata/simple_pattern#simple-patterns). | localhost * | no | +| send charts matching | One or more space separated patterns (use * as wildcard) checked against both chart id and chart name. | * | no | +| send names instead of ids | Controls the metric names Netdata should send to the external database (yes/no). | | no | +| send configured labels | Controls if host labels defined in the `[host labels]` section in `netdata.conf` should be sent to the external database (yes/no). | | no | +| send automatic labels | Controls if automatically created labels, like `_os_name` or `_architecture` should be sent to the external database (yes/no). | | no | + +##### destination + +The format of each item in this list, is: [PROTOCOL:]IP[:PORT]. +- PROTOCOL can be udp or tcp. tcp is the default and only supported by the current exporting engine. +- IP can be XX.XX.XX.XX (IPv4), or [XX:XX...XX:XX] (IPv6). For IPv6 you can to enclose the IP in [] to separate it from the port. +- PORT can be a number of a service name. If omitted, the default port for the exporting connector will be used. + +Example IPv4: + ```yaml + destination = 10.11.14.2:27017 10.11.14.3:4242 10.11.14.4:27017 + ``` +Example IPv6 and IPv4 together: +```yaml +destination = [ffff:...:0001]:2003 10.11.12.1:2003 +``` +When multiple servers are defined, Netdata will try the next one when the previous one fails. + + +##### update every + +Netdata will add some randomness to this number, to prevent stressing the external server when many Netdata servers +send data to the same database. This randomness does not affect the quality of the data, only the time they are sent. + + +##### buffer on failures + +If the server fails to receive the data after that many failures, data loss on the connector instance is expected (Netdata will also log it). + + +##### send hosts matching + +Includes one or more space separated patterns, using * as wildcard (any number of times within each pattern). +The patterns are checked against the hostname (the localhost is always checked as localhost), allowing us to +filter which hosts will be sent to the external database when this Netdata is a central Netdata aggregating multiple hosts. + +A pattern starting with `!` gives a negative match. So to match all hosts named `*db*` except hosts containing `*child*`, +use `!*child* *db*` (so, the order is important: the first pattern matching the hostname will be used - positive or negative). + + +##### send charts matching + +A pattern starting with ! gives a negative match. So to match all charts named apps.* except charts ending in *reads, +use !*reads apps.* (so, the order is important: the first pattern matching the chart id or the chart name will be used, +positive or negative). There is also a URL parameter filter that can be used while querying allmetrics. The URL parameter +has a higher priority than the configuration option. + + +##### send names instead of ids + +Netdata supports names and IDs for charts and dimensions. Usually IDs are unique identifiers as read by the system and names +are human friendly labels (also unique). Most charts and metrics have the same ID and name, but in several cases they are +different : disks with device-mapper, interrupts, QoS classes, statsd synthetic charts, etc. + + +</details> + +#### Examples + +##### Basic configuration + +The default socket timeout depends on the exporting connector update interval. +The timeout is 500 ms shorter than the interval (but not less than 1000 ms). You can alter the timeout using the sockettimeoutms MongoDB URI option. + + +```yaml +[mongodb:my_instance] + enabled = yes + destination = mongodb://<hostname> + database = your_database_name + collection = your_collection_name + +``` + |
