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
• Configuration precedence
• InfluxDB configuration file
• Configuration options

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

YAML TOML JSON

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,

  "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.
