Identifying which InfluxDB product and version you're using is essential for accessing the correct documentation, troubleshooting issues, and planning upgrades.

Quick detection methods

{{% hide-in "core,enterprise,cloud-serverless,cloud-dedicated,clustered,v2,cloud,v1" %}}

By URL pattern

If you access InfluxDB via a URL, the hostname often indicates which product you're using:

URL Pattern Product
*.influxdb.io InfluxDB Cloud Dedicated
us-east-1-1.aws.cloud2.influxdata.com InfluxDB Cloud Serverless
eu-central-1-1.aws.cloud2.influxdata.com InfluxDB Cloud Serverless
*.influxcloud.net InfluxDB Cloud 1 (legacy)
Other *.cloud2.influxdata.com regions InfluxDB Cloud (TSM)

By default port

Different InfluxDB products use different default ports:

  • Port 8181: InfluxDB 3 (Core or Enterprise)
  • Port 8086: InfluxDB v1 or v2

By HTTP headers

Send a GET request to the /ping endpoint to examine HTTP response headers--for example:

# InfluxDB 3 (port 8181)
curl -i http://localhost:8181/ping

# InfluxDB v1/v2 (port 8086)
curl -i http://localhost:8086/ping

The response headers reveal your InfluxDB product:

Headers Product
x-influxdb-version: ^3.*
x-influxdb-build: Core		 InfluxDB 3 Core
x-influxdb-version: ^3.*
x-influxdb-build: Enterprise		 InfluxDB 3 Enterprise
x-influxdb-version: ^2.*
x-influxdb-build: OSS		 InfluxDB OSS v2
x-influxdb-version: ^1.*
x-influxdb-build: OSS		 InfluxDB OSS v1
x-influxdb-build: Enterprise
(with v1 version)		 InfluxDB Enterprise v1

InfluxDB 3 version detection

Check the version using the influxdb3 command:

influxdb3 --version

Send a GET request to the /ping endpoint to examine HTTP response headers--for example:

curl -i http://localhost:8181/ping

The response includes version information in the headers and body:

  • Headers:
    • x-influxdb-version: Version number (for example, {{% latest-patch %}})
    • x-influxdb-build: {{% show-in "core" %}}Core{{% /show-in %}}{{% show-in "enterprise" %}}Enterprise{{% /show-in %}}
  • JSON body: Contains version, revision, and process_id

Example response:

HTTP/1.1 200 OK
x-influxdb-build: {{% show-in "core" %}}Core{{% /show-in %}}{{% show-in "enterprise" %}}Enterprise{{% /show-in %}}
x-influxdb-version: {{% latest-patch %}}

{"version":"{{% latest-patch %}}","revision":"abc123def","process_id":"..."}

{{% show-in "enterprise" %}}

[!Note] The /ping endpoint requires authentication by default in InfluxDB 3 Enterprise. Use an admin token or a system token with system:ping:read permission. {{% /show-in %}}

{{% /show-in %}}

{{% show-in "clustered" %}}

InfluxDB Clustered detection

Use the influxctl CLI to check your cluster version:

influxctl version

To view cluster information:

influxctl cluster list

{{% /show-in %}}

{{% show-in "cloud-serverless" %}}

InfluxDB Cloud Serverless detection

InfluxDB Cloud Serverless can be identified by:

URL patterns:

  • us-east-1-1.aws.cloud2.influxdata.com
  • eu-central-1-1.aws.cloud2.influxdata.com

Account settings: Check your InfluxDB Cloud account dashboard for product and version details.

HTTP headers: API responses include version information in response headers.

{{% /show-in %}}

{{% show-in "cloud-dedicated" %}}

InfluxDB Cloud Dedicated detection

InfluxDB Cloud Dedicated can be identified by:

URL pattern: *.influxdb.io

  • Example: cluster-id.a.influxdb.io

Account settings: Check your InfluxDB Cloud Dedicated account dashboard for cluster and version details.

HTTP headers: API responses include version information in response headers.

{{% /show-in %}}

{{% hide-in "v2,cloud,v1" %}}

[!Note]

SQL version() function

The SQL version() function returns the DataFusion query engine version, not the InfluxDB product version. Use the methods above to identify your InfluxDB version. {{% /hide-in %}}

{{% show-in "v2" %}}

InfluxDB OSS v2 detection

Check the version using influxd:

influxd version

Query the /health endpoint and extract the version:

curl -s http://localhost:8086/health | jq -r '.version'

The InfluxDB UI displays the version:

  • On the login page
  • In the right column of the main landing page
  • In the user menu dropdown

For more details, see How can I identify my InfluxDB version?

{{% show-in "cloud" %}}

InfluxDB Cloud (TSM) detection

InfluxDB Cloud (TSM) can be identified by:

URL patterns (regional cloud2.influxdata.com URLs, excluding Serverless regions):

  • us-west-2-1.aws.cloud2.influxdata.com
  • us-west-2-2.aws.cloud2.influxdata.com
  • us-east-1-2.aws.cloud2.influxdata.com (note: different from Serverless)
  • us-central1-1.gcp.cloud2.influxdata.com
  • westeurope-1.azure.cloud2.influxdata.com
  • eastus-1.azure.cloud2.influxdata.com

Account settings: Check your InfluxDB Cloud account dashboard for product details.

HTTP headers: API responses include version information in response headers.

{{% /show-in %}}

{{% show-in "v1" %}}

InfluxDB OSS v1 / Enterprise v1 detection

Check the version using influxd:

influxd version

Check the /ping endpoint headers:

curl -i http://localhost:8086/ping

Look for the x-influxdb-version header (for example, 1.11.7).

For Enterprise v1, the x-influxdb-build header will show Enterprise.

Troubleshooting

Can't access your InfluxDB instance?

If you can't directly access your InfluxDB instance:

  1. Use the interactive version detector above or {{< ask-ai-link link-text="Ask InfluxData AI" query="Help determine my InfluxDB version based on licensing, hosting, server age, and API." >}}
  2. Answer questions about your setup:
    • License type (paid or free)
    • Hosting model (cloud or self-hosted)
    • Server age
    • Query language preferences
  3. Get product recommendations based on your answers
