influxd-ctl leave

The influxd-ctl leave command removes a meta or data node from an InfluxDB Enterprise cluster. The command searches for influxd and influxd-meta processes running on the local machine bound to specific ports and determines if that process is an InfluxDB meta or data node.

  • 8088: Data node
  • 8091: Meta node

If the InfluxDB data or meta processes are running on non-default ports, the leave operation cannot detect them.

This command is destructive

influxd-ctl leave erases all metastore information from meta nodes and all data from data nodes. Only use this command if you want to permanently remove a node from your InfluxDB Enterprise cluster.

Usage

influxd-ctl leave [flags]

Flags

FlagDescription
-yAssume yes to all prompts

Examples

Remove nodes from a cluster

In the following example, influxd-ctl leave detects the meta node running at cluster-node-03:8091 and the data node running at cluster-node-03:8088 in an existing InfluxDB Enterprise cluster and prompts the user to remove them.

influxd-ctl leave
Command output and interactive prompts
Searching for data node on cluster-node-03:8088...
Remove data node cluster-node-03:8088 from the cluster [y/N]: y
Removed cluster-node-03:8088 from the cluster
Searching for meta node on cluster-node-03:8091...
Remove meta node cluster-node-03:8091 from the cluster [y/N]: y

Successfully left cluster

  * Removed data node cluster-node-03:8088 from cluster
  * Removed meta node cluster-node-03:8091 from cluster

Remove nodes from a cluster and assume yes to all prompts

In the following example, influxd-ctl leave detects the meta node running at cluster-node-03:8091 and the data node running at cluster-node-03:8088 in an existing InfluxDB Enterprise cluster and then, without prompting for input, removes them from the cluster:

influxd-ctl leave -y
Command output
Searching for data node on cluster-node-03:8088...
Removed cluster-node-03:8088 from the cluster
Searching for meta node on cluster-node-03:8091...

Successfully left cluster

  * Removed data node cluster-node-03:8088 from cluster
  * Removed meta node cluster-node-03:8091 from cluster

InfluxDB OSS 2.9.0: API tokens are hashed by default

Stronger token security in InfluxDB OSS 2.9.0 — tokens are hashed on disk by default. Existing tokens are hashed on first startup and can’t be recovered afterward. Capture any plaintext tokens you still need before you upgrade.

View InfluxDB OSS 2.9.0 release notes

Hashed tokens authenticate exactly like unhashed tokens — clients and integrations keep working.

Also new in 2.9.0:

  • Configurable backup compression
  • Restore support for backups containing hashed tokens
  • Tighter Edge Data Replication queue validation
  • Flux upgrade
  • Compaction reliability improvements

Key enhancements in Explorer 1.9

Explorer 1.9 is now available with InfluxQL support, an AI-assisted Flux to SQL converter (beta), and new live sample data simulators.

View Explorer 1.9 release notes

Explorer 1.9 includes new features and improvements that make it easier to query, visualize, and manage data.

Highlights:

  • Flux to SQL converter (beta): Convert Flux queries to SQL with an AI-assisted converter.
  • InfluxQL support: Query data with InfluxQL in the Data Explorer and dashboards, and save and load InfluxQL queries.
  • InfluxQL visualizations: Render line and bar charts from InfluxQL results with per-tag series grouping.
  • Query error history: Review a history of query errors in the query tool.
  • Live sample data simulators: Generate continuous live sample data with new bird data and signal generator simulators.

InfluxDB 3.10 is now available

InfluxDB 3 Core 3.10 adds an automatic catalog format upgrade, a configurable query-concurrency limit, and processing engine improvements.

Key updates in InfluxDB 3 Core 3.10:

  • Catalog format upgrade: the on-disk catalog automatically upgrades from format v2 to v3 on first 3.10 startup. Migration is one-way—back up your catalog before upgrading.
  • --max-concurrent-queries: limit concurrent queries (adjustable at runtime).
  • GET /ready endpoint for readiness probes.
  • Processing engine: cross-database queries and trigger lockdown flags.

For more information, see the InfluxDB 3 Core release notes.

InfluxDB 3.10 is now available

InfluxDB 3 Enterprise 3.10 adds automated backup and restore, row-level deletions, and user management, with an automatic catalog format upgrade and performance preview improvements.

Key updates in InfluxDB 3 Enterprise 3.10:

  • Catalog format upgrade: the on-disk catalog automatically upgrades from format v2 to v3 on first 3.10 startup. Migration is one-way—back up your catalog before upgrading.
  • Automated backup and restore (beta)
  • Row-level deletions
  • User management (authentication and RBAC) — preview
  • Performance preview improvements

Backup and restore, row-level deletions, and the performance preview require the Enterprise storage engine upgrade (opt-in beta). Beta and preview features are subject to breaking changes and aren’t recommended for production use.

Telegraf Enterprise is now generally available

Telegraf Enterprise is now generally available, along with Telegraf Controller v1.0.

Telegraf Enterprise combines Telegraf Controller, a centralized management console for Telegraf, with official support from InfluxData. Manage configurations, monitor fleet health, and operate tens of thousands of Telegraf agents from a single system.

InfluxDB Docker latest tag changing to InfluxDB 3 Core

On September 15, 2026, the latest tag for InfluxDB Docker images will point to InfluxDB 3 Core. To avoid unexpected upgrades, use specific version tags in your Docker deployments.

If using Docker to install and run InfluxDB, the latest tag will point to InfluxDB 3 Core. To avoid unexpected upgrades, use specific version tags in your Docker deployments. For example, if using Docker to run InfluxDB v2, replace the latest version tag with a specific version tag in your Docker pull command–for example:

docker pull influxdb:2
