The influxdb output plugin, allows to flush your records into a InfluxDB time series database. The following instructions assumes that you have a fully operational InfluxDB service running in your system.

Configuration Parameters

Key Description default
Host IP address or hostname of the target InfluxDB service
Port TCP port of the target InfluxDB service 8086
Database InfluxDB database name where records will be inserted fluentbit
Sequence_Tag The name of the tag whose value is incremented for the consecutive simultaneous events. _seq


InfluxDB output plugin supports TTL/SSL, for more details about the properties available and general configuration, please refer to the TLS/SSL section.

Getting Started

In order to start inserting records into an InfluxDB service, you can run the plugin from the command line or through the configuration file:

Command Line

The influxdb plugin, can read the parameters from the command line in two ways, through the -p argument (property) or setting them directly through the service URI. The URI format is the following:


Using the format specified, you could start Fluent Bit through:

$ fluent-bit -i cpu -t cpu -o influxdb:// -m '*'

Configuration File

In your main configuration file append the following Input & Output sections:

    Name  cpu
    Tag   cpu

    Name          influxdb
    Match         *
    Port          8086
    Database      fluentbit
    Sequence_Tag  _seq


Before to start Fluent Bit, make sure the target database exists on InfluxDB, using the above example, we will insert the data into a fluentbit database.

1. Create database

Log into InfluxDB console:

$ influx
Visit to register for updates, InfluxDB server management, and monitoring.
Connected to http://localhost:8086 version 1.1.0
InfluxDB shell version: 1.1.0

Create the database:

> create database fluentbit

Check the database exists:

> show databases
name: databases


2. Run Fluent Bit

The following command will gather CPU metrics from the system and send the data to InfluxDB database every five seconds:

$ bin/fluent-bit -i cpu -t cpu -o influxdb -m '*'

Note that all records coming from the cpu input plugin, have a tag cpu, this tag is used to generate the measurement in InfluxDB

3. Query the data

From InfluxDB console, choose your database:

> use fluentbit
Using database fluentbit

Now query some specific fields:

> SELECT cpu_p, system_p, user_p FROM cpu
name: cpu
time                  cpu_p   system_p    user_p
----                  -----   --------    ------
1481132860000000000   2.75        0.5      2.25
1481132861000000000   2           0.5      1.5
1481132862000000000   4.75        1.5      3.25
1481132863000000000   6.75        1.25     5.5
1481132864000000000   11.25       3.75     7.5

The CPU input plugin gather more metrics per CPU core, in the above example we just selected three specific metrics. The following query will give a full result:
