InfluxDB configuration options

Customize your InfluxDB configuration by using influxd configuration flags, setting environment variables, or defining configuration options in a configuration file.

View your runtime server configuration

Use the influx CLI or the InfluxDB API to get the runtime server configuration of your InfluxDB instance.

Server configuration commands require an Operator token.

View your server configuration with the CLI

Use the influx server-config command to retrieve your runtime server configuration.

influx server-config

View your server configuration with the API

Use the /api/v2/config InfluxDB API endpoint to retrieve your runtime server configuration.

GET http://localhost:8086/api/v2/config

Configuration precedence

InfluxDB honors configuration settings using the following precedence:

  1. influxd flags
  2. Environment variables
  3. Configuration file settings

InfluxDB configuration file

When influxd starts, it checks for a file named config.* in the current working directory. The file extension depends on the syntax of the configuration file. InfluxDB configuration files support the following syntaxes:

  • YAML (.yaml, .yml)
  • TOML (.toml)
  • JSON (.json)

To customize the directory path of the configuration file, set the INFLUXD_CONFIG_PATH environment variable to your custom path.

export INFLUXD_CONFIG_PATH=/path/to/custom/config/directory

On startup, influxd will check for a config.* in the INFLUXD_CONFIG_PATH directory.

Example configuration file
query-concurrency: 20
query-queue-size: 15
secret-store: vault
session-length: 120
tls-cert: /path/to/influxdb.crt
tls-key: /path/to/influxdb.key
query-concurrency = 20
query-queue-size = 15
secret-store = "vault"
session-length = 120
tls-cert = "/path/to/influxdb.crt"
tls-key = "/path/to/influxdb.key"
{
  "query-concurrency": 20,
  "query-queue-size": 15,
  "secret-store": "vault",
  "session-length": 120,
  "tls-cert": "/path/to/influxdb.crt",
  "tls-key": "/path/to/influxdb.key"
}

Only non-default settings need to be defined in the configuration file.

Configuration options

To configure InfluxDB, use the following configuration options when starting the influxd service:


assets-path

Override the default InfluxDB user interface (UI) assets by serving assets from the specified directory. Typically, InfluxData internal use only.

influxd flag Environment variable Configuration key
--assets-path INFLUXD_ASSETS_PATH assets-path
influxd flag
influxd --assets-path=/path/to/custom/assets-dir
Environment variable
export INFLUXD_ASSETS_PATH=/path/to/custom/assets-dir

assets-path = "/path/to/custom/assets-dir"
{
  "assets-path": "/path/to/custom/assets-dir"
}

bolt-path

Path to the BoltDB database. BoltDB is a key value store written in Go. InfluxDB uses BoltDB to store data including organization and user information, UI data, REST resources, and other key value data.

storage-series-id-set-cache-size

Size of the internal cache used in the TSI index to store previously calculated series results. Cached results are returned quickly rather than needing to be recalculated when a subsequent query with the same tag key/value predicate is executed. Setting this value to 0 will disable the cache and may decrease query performance.

Default: 100

This value should only be increased if the set of regularly used tag key/value predicates across all measurements for a database is larger than 100. An increase in cache size may lead to an increase in heap usage.

The future of Flux

Flux is going into maintenance mode. You can continue using it as you currently are without any changes to your code.

Flux is going into maintenance mode and will not be supported in InfluxDB 3.0. This was a decision based on the broad demand for SQL and the continued growth and adoption of InfluxQL. We are continuing to support Flux for users in 1.x and 2.x so you can continue using it with no changes to your code. If you are interested in transitioning to InfluxDB 3.0 and want to future-proof your code, we suggest using InfluxQL.

For information about the future of Flux, see the following:
