Have you ever seen an administrator rush for the server room to fix a development server ? I guess not. But for production ones, they do ;-). Your team should focus on production, and manage the other environment later. Give them the tools taking this into account.
Filtering testing/production alerts
While problems on production need to trigger a SMS, the testing environment probably doesn't. With Shinken you can easily filter root problem alarms to only receive notifications that really NEED action.
Day != Night
You may not need to receive SMS during the day, or and e-mails during the night. With Shinken you can easily manage notification canals without having to add another layer of complexity to your configuration.
Sometime it's critical for business, sometime it's not
The payroll application is a good example. Do you need to wake the administrator at 3AM because the server hosting it is down? Probably not... Unless of course we are nearing the payroll! With Shinken you are able to define business impact modulations based on the period, like the 3 days at the end of the month :).
