Modifying the Auto UI Logout Timeout – Redis Knowledge Base

Redis Software automatically logs users out of the Cluster Manager UI after a period of inactivity—by default, 15 minutes. You can configure this Auto UI Logout Timeout (session timeout) to better align with your environment's security or usability needs. This guide explains how to adjust the timeout using the Cluster Manager UI, rladmin CLI, or the REST API, and includes a Troubleshooting section and a summary of available commands. Timeout customization via UI is available in versions 6.2.12 and later, with version-specific path variations noted for 7.2 and earlier.

Prerequisites

Admin access required

You must have administrative privileges on the Redis cluster to make changes.

Version requirements

Full session timeout customization in the UI is supported in Redis Software 7.4+.
UI paths for versions prior to 7.2 differ slightly (noted below).

Step-by-Step Instructions

Change Timeout via Cluster Manager UI

Redis Software 7.4+:
- Go to: Cluster > Security > Preferences
- Click Edit, locate the Session timeout field
- Choose the unit (minutes or hours) and enter your desired value
- Click Save

Redis Software <7.2:
- Go to: Settings > Preferences > Session timeout

Change Timeout via CLI (rladmin)

To set the session timeout from any node:

rladmin cluster config cm_session_timeout_minutes <number_of_minutes>

To verify the current session timeout:

rladmin info cluster | grep cm_session_timeout_minutes

Change Timeout via REST API

Send a PUT request to the /v1/cluster endpoint:

curl -u <admin-email>:<password> \
     -X PUT \
     -H "Content-Type: application/json" \
     -k \
     -d '{"cm_session_timeout_minutes": <number_of_minutes>}' \
     https://<your-cluster-host>:9443/v1/cluster

Replace <admin-email>, <password>, and <your-cluster-host> as appropriate
A successful response confirms the setting has been applied

Troubleshooting

Issue	Likely Cause	Recommended Action
Users logged out before configured timeout	Browser cache or session handling	Clear cookies/cache, use incognito mode, or try a different browser
Timeout setting doesn’t take effect	Unsaved changes or missing admin privileges	Save changes and verify user role has admin permissions
Timeout value not updated	Verification step missed	Run `rladmin info cluster` to confirm setting
Logout persists despite updates	External browser/system interference	Collect logs, check browser sleep/power/network settings, and contact Redis Support

Summary: Timeout Configuration Commands

Method	Command or Path
UI	`Cluster > Security > Preferences > Session Timeout` (7.4+) `Settings > Preferences` (pre-7.2)
CLI	`rladmin cluster config cm_session_timeout_minutes <X>`
REST API	`PUT /v1/cluster { "cm_session_timeout_minutes": <X> }`
