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.

1. influx server-config

View your server configuration with the API

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

1. 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.

1. 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

1. query-concurrency: 20
2. query-queue-size: 15
3. secret-store: vault
4. session-length: 120
5. tls-cert: /path/to/influxdb.crt
6. tls-key: /path/to/influxdb.key

1. query-concurrency = 20
2. query-queue-size = 15
3. secret-store = "vault"
4. session-length = 120
5. tls-cert = "/path/to/influxdb.crt"
6. tls-key = "/path/to/influxdb.key"

1. {
2. "query-concurrency": 20,
3. "query-queue-size": 15,
4. "secret-store": "vault",
5. "session-length": 120,
6. "tls-cert": "/path/to/influxdb.crt",
7. "tls-key": "/path/to/influxdb.key"
8. }

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

influxd flag

1. influxd --storage-no-validate-field-size

Environment variable

1. export INFLUXD_STORAGE_NO_VALIDATE_FIELD_SIZE=true

Configuration file

YAML TOML JSON

1. storage-no-validate-field-size: true

1. storage-no-validate-field-size = true

1. {
2. "storage-no-validate-field-size": true
3. }

storage-retention-check-interval

Interval of retention policy enforcement checks.

Default: 30m0s

influxd flag

1. influxd --storage-retention-check-interval=30m0s

Environment variable

1. export INFLUXD_STORAGE_RETENTION_CHECK_INTERVAL=30m0s

Configuration file

YAML TOML JSON

1. storage-retention-check-interval: 30m0s

1. storage-retention-check-interval = "30m0s"

3. }

storage-series-file-max-concurrent-snapshot-compactions

Default: 0

influxd flag

1. influxd --storage-series-file-max-concurrent-snapshot-compactions=0

Environment variable

1. {
2. "storage-series-file-max-concurrent-snapshot-compactions": 0
3. }

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.

Environment variable

1. export INFLUXD_STORAGE_SHARD_PRECREATOR_ADVANCE_PERIOD=30m0s

storage-wal-fsync-delay

Duration a write will wait before fsyncing. A duration greater than 0 batches multiple fsync calls. This is useful for slower disks or when WAL write contention is present.

1. storage-wal-max-write-delay = "10m"

1. {
2. "storage-wal-max-write-delay": "10m"

storage-write-timeout

Maximum amount of time the storage engine will process a write request before timing out.

Default: 10s
