“The Phoenix Project” – An Outline to DevOps Success
By: Andy Hart >>
The Phoenix Project Book
I recently read a great novel, “The Phoenix Project” by Gene Kim et al.

Use Process Sets to Monitor More Efficiently and Reduce Monitoring Costs
If you are like most IT Operations folks, you always have too much to do with too little time. Change management moves at the speed of light. New applications get deployed by someone on the business apps team, but this information never makes it over to the IT Operations team. This means that the application is partially or totally off the grid and unmonitored. The first time you even realize it exists is when there is a performance or availability problem and your end users start calling in and complaining. It seems like there just aren’t enough hours in the day to track all of the new applications coming up, let alone effectively monitor them.
You know that in order to fully understand the load on your system resources, you need to know about the performance of each critical process associated with an application or service running on the server. However, knowing what processes are important for different applications and configuring the monitoring processes individually is very labor-intensive. Process monitoring consumes even more of your already limited cycles ─ unless you have a dynamic, easy-to-maintain, rules-based approach to process monitoring.
