Use the Prometheus remote write exporting connector to archive your Netdata metrics to the external storage provider of your choice for long-term storage and further analysis.

Limitations

The remote write exporting connector does not support buffer on failures.

Setup

Prerequisites

• Netdata and the external storage provider of your choice, installed, configured and operational.
• protobuf and snappy libraries installed.
• Netdata reinstalled after the libraries.

Configuration

File

The configuration file name for this integration is exporting.conf.

You can edit the configuration file using the edit-config script from the Netdata config directory.

cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config exporting.conf

Options

The following options can be defined for this exporter.

Config options

Name	Description	Default	Required
enabled	Enables or disables an exporting connector instance (yes/no).	no	yes
destination	Accepts a space separated list of hostnames, IPs (IPv4 and IPv6) and ports to connect to. Netdata will use the first available to send the metrics.	no	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.	20000	no
send hosts matching	Hosts filter. Determines which hosts will be sent to the external database. The syntax is 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:

destination = 10.11.14.2:2003 10.11.14.3:4242 10.11.14.4:2003

Example IPv6 and IPv4 together:

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.

Examples

Example configuration

Basic example configuration for Prometheus remote write.

[prometheus_remote_write:my_instance]
    enabled = yes
    destination = 10.11.14.2:2003
    remote write URL path = /receive

Example configuration with HTTPS and HTTP authentication

Add :https modifier to the connector type if you need to use the TLS/SSL protocol. For example: remote_write:https:my_instance.

[prometheus_remote_write:https:my_instance]
    enabled = yes
    destination = 10.11.14.2:2003
    remote write URL path = /receive
    username = my_username
    password = my_password
