InfluxDB configuration options

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

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
Configuration file
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.

Default: ~/.influxdbv2/influxd.bolt

influxd flag Environment variable Configuration key
--bolt-path INFLUXD_BOLT_PATH bolt-path
influxd flag
influxd --bolt-path=~/.influxdbv2/influxd.bolt
Environment variable
export INFLUXD_BOLT_PATH=~/.influxdbv2/influxd.bolt
Configuration file
bolt-path: /users/user/.influxdbv2/influxd.bolt
bolt-path = "/users/user/.influxdbv2/influxd.bolt"
{
  "bolt-path": "/users/user/.influxdbv2/influxd.bolt"
}

e2e-testing

Add a /debug/flush endpoint to the InfluxDB HTTP API to clear stores. InfluxData uses this endpoint in end-to-end testing.

influxd flag Environment variable Configuration key
--e2e-testing INFLUXD_E2E_TESTING e2e-testing
influxd flag
influxd --e2e-testing
Environment variable
export INFLUXD_E2E_TESTING=true
Configuration file
e2e-testing: true
e2e-testing = true
{
  "e2e-testing": true
}

engine-path

Path to persistent storage engine files where InfluxDB stores all Time-Structure Merge Tree (TSM) data on disk.

Default: ~/.influxdbv2/engine

influxd flag Environment variable Configuration key
--engine-path INFLUXD_ENGINE_PATH engine-path
influxd flag
influxd --engine-path=~/.influxdbv2/engine
Environment variable
export INFLUXD_ENGINE_PATH=~/.influxdbv2/engine
Configuration file
engine-path: /users/user/.influxdbv2/engine
engine-path = "/users/user/.influxdbv2/engine"
{
  "engine-path": "/users/user/.influxdbv2/engine"
}

http-bind-address

Bind address for the InfluxDB HTTP API. Customize the URL and port for the InfluxDB API and UI.

Default: :8086

influxd flag Environment variable Configuration key

influxd flag
influxd --http-bind-address=:8086
Environment variable
export INFLUXD_HTTP_BIND_ADDRESS=:8086
Configuration file
http-bind-address: ":8086"
http-bind-address = ":8086"
{
  "http-bind-address": ":8086"
}

http-idle-timeout

Maximum duration the server should keep established connections alive while waiting for new requests. Set to 0 for no timeout.

Default: 3m0s

influxd flag Environment variable Configuration key
--http-idle-timeout INFLUXD_HTTP_IDLE_TIMEOUT http-idle-timeout
influxd flag
influxd --http-idle-timeout=3m0s
Environment variable
export INFLUXD_HTTP_IDLE_TIMEOUT=3m0s
Configuration file

http-idle-timeout = "3m0s"
{
  "http-idle-timeout": "3m0s"
}

http-read-header-timeout

Maximum duration the server should try to read HTTP headers for new requests. Set to 0 for no timeout.

Default: 10s

influxd flag Environment variable Configuration key

}

http-read-timeout

Maximum duration the server should try to read the entirety of new requests. Set to 0 for no timeout.

Default: 0

Set timeouts specific to your workload

Although no http-read-timeout is set by default, we strongly recommend setting a timeout specific to your workload. HTTP timeouts protect against large amounts of open connections that could potentially hurt performance.

influxd flag Environment variable Configuration key
--http-read-timeout INFLUXD_HTTP_READ_TIMEOUT http-read-timeout

http-write-timeout

Maximum duration the server should spend processing and responding to write requests. Set to 0 for no timeout.

Default: 0

Set timeouts specific to your workload

Although no http-write-timeout is set by default, we strongly recommend setting a timeout specific to your workload. HTTP timeouts protect against large amounts of open connections that could potentially hurt performance.

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.
