NotificationsTuning

This page describes a team organization example, and how we send notifications. We talk about an IT team, managing servers and applications.

Introduction

We have in our RT many queues, and from 2 to 4 adminccs per queue. The incoming tickets arrive in an INCOMING queue and are dispatched by some people to the appropriate queue. When a ticket enters a queue, it belongs to nobody and one of the adminccs takes the ticket (depending on the workload of each others, holidays etc...). Then the ticket lives and is resolved. I describe here the notifications we use, hoping it will help people. Any comments/optimizations/etc are welcome at the end of the file.

Summary

When a new ticket is created :

  • notify requestor with an autoreply
  • notify owner he has a new ticket (if the ticket was created and assigned at the same time)
  • notify adminccs of the queue that a new ticket is available in their queue

When there is an owner change :

  • notify (new) owner
  • notify other adminccs that the ticket is taken by one of them (so they don't have to take care of it)

When there is a queue change :

  • notify adminccs of the new queue there is a new ticket

When there is a correspondance on a ticket (reply):

  • notify requestors, ccs
  • notify other recipients
  • notify owner
  • notify adminccs

When there is a comment on a ticket :

  • notify owner
  • notify admincc

When a ticket is resolved :

  • notify requestor
  • notify adminccs someone (one of them) resolved the ticket

I created new templates starting with "MY" and associated them to scrips. I put in these templates what makes sense to me, and I added a line explaining the reason why you receive this mail.

Patch to send less notifications

But with this configuration (and with the default one), we had a problem : we received too many emails for the same thing : For example :

  • a (privilieged) user sends a request to RT for a task he has to do.
  • people managing tickets assign it to him, and put it in a queue he is admincc for

So this user is requestor, owner, and admincc : he gets 3 emails on each correspondance.

This is the patch (ugly patch but it works) I applied to lib/RT/Action/Notify.pm (well, I created a new file local/lib/RT/Action/Notify.pm) . It has been tested on RT 3.8.2 and 3.8.7 :

     }

     if ( RT->Config->Get('UseFriendlyToLine') ) {


This is what the patch does :

  • always send an email to the requestor for a correspondance ("Reply")
  • if user is requestor and owner, do not send to the owner (an email has already been sent to the requestor)
  • if a user is requestor or owner and admincc, remove him from the list of admincc (as he has already been notified either because he's a requestor or a owner) and send the email to this list of admincc .

That also means the template received by the user depends on his role (sometimes he will receive the requestor template, sometimes the owner, sometimes the admincc). But as basically it's the same thing, we don't mind.

This is the test matrix :

ROA  | S |  P | T
 ------------------
 000  | x |  x | x
 001  | 1 |  1 | A
 010  | 1 |  1 | O
 011  | 2 |  1 | O
 100  | 1 |  1 | R
 101  | 2 |  1 | R
 110  | 2 |  1 | R
 111  | 3 |  1 | R
 
  • R : is requestor
  • O : is owner
  • A : is admincc
  • S : Number of emails sent with Standard notify.pm
  • P : Number of emails sent with Patched notify.pm
  • T : Template used (Requestor, Owner, AdminCc)

I've not managed the Cc part, and the comments because our main problem was the duplicate emails generated by correspondences.

And it works very well. No more useless notifications.
