Issue Reminder

(Redmine Plugin)

Avoid bottlenecks!

The Issue Reminder Plugin adds the functionality to send issue reminders automatically and manually to assignees or authors.
Auxiliary-X offers a cron-like script to call the automatic reminder rake task as well as any other program or task you defined in the Auxiliary-X cron file.
There is no need to use a rails scheduler or built in cron from your docker container.
Manual reminders can be sent to open issues by any user who has the access rights to view the regarding issue and send reminders. The reminded user receives an email about the regarding issue, regardless of the chosen email notification settings. Reminded issues are collected in a reminder overview and disappear as soon as the issue is closed or delegated to another user.
The available reminder statistic shows to every project member the number of reminders for open issues. The statistic displays manually and automatically sent reminders separately for open issues and provides an indicator about current bottlenecks in the project. Rules for automatically sent reminders can be defined by creating standard issue queries and adding them as rules to the reminder settings of the project.


  • issue view extension for manual reminder option
  • bulk email can be sent to a group which is assigned to an issue
  • scheduled automatic reminders
  • define project customized automatic reminder rules with standard issue queries
  • task scheduling without standard docker cron or rails scheduler
  • reminder overview
  • reminder statistic as a new form of KPI
  • activity reminder item

Auxiliary-X Cron Script

Configure the Auxiliary-X cron file

The Auxiliary-X cron-like script accepts the well-known standard syntax from cron for time scheduling.
The script does not depend on the docker cron or any other rails scheduler. You can freely add any kind of command to this file, which can be called via bash, in order to schedule your customized jobs.
By default the Auxiliary-X cron file contains the command to call the auto reminder rake task every day at 01:01 am.

#Calls the auto reminder from the Auxiliary-X Issue Reminder Plugin.
1 1 * * * rake auxiliary_x:auto_reminder --silent

Manual Issue Reminders

The issue reminder button is attached to every open issue. A simple click reminds the assignee via email and in the “My reminders” tab to work on the issue. If the issue has no assignee or the assignee is locked the author receives the reminder. The email will be sent regardless of the receivers email notification settings.

The manually issued email contains the person who reminded you and a preview of the reminded issue.

Automatic Issue Reminders

Automatic issue reminders are issued according to project specific rules. Each rule consists of a standard Redmine issue query. The user can use all available query filters to build the underlying query.

When saving the query it is important to select the option ” Visible: to any users ” and leave For all projects: unselected. Choose a proper name and save the query.

The query will appear under “Custom Queries” and can be selected to define an automatic reminder rule.

By navigating to

 Settings -> Reminders -> Add rule

the desired query can be selected and saved as a new rule.

All active automatic reminder rules are shown in the list. By pressing the delete button, the rule will be deleted but the query remains in the project.

Automatically generated reminders are issued, when the automatic issue reminder task iterates through all rules at a defined time.
The time is defined in the Auxiliary-X cron file by the system admin.

Reminder Overview

Every member of a project, who has the right to view the “My reminders” tab, has access to the reminders list. The list shows only open issues. The reminder will disappear when the issue is closed or delegated to another user.

Reminder Statistic

The statistic displays manually and automatically sent reminders separately for open issues and provides an indicator about current bottlenecks in the project.

Activity Item

Every issued reminder appears as an event in the activity tab.

Issue-Deadlock Notification

Manually sent reminders for issues where the author and assignee are locked are forwarded to the Redmine Admin. This is an easy way of informing the admin to resolve the deadlock of this issue.

Larry Locker and Bernd Blocker are locked in this example. The admin will receive an email as shown.
