Service Weather: Blocking or Degrading?

Back to news

As we have seen  in many other blog articles, the IT service weather is a simple way to communicate to managers, users, support, customers, …

Simple to understand (sun, cloud or rain) and at the same time accurately reporting the availability rate, IT weather provides for each user service (each “business application”), a real time view of the health of the application as well as calculating its availability over a selected interval.

Sharing this information is a real benefit to support staff, freeing them up to deal with their day to day tasks, especially during incidents.

At the heart of this communication is the need to avoid the financial implications of missed SLAs. Consequently, each user service must be built accurately and precisely to deliver the right information at the right time.

 

Elements of a user service and links

A user service is a functional representation of a business service or process; consisting of a set of technical checks linked together in a dependency hierarchy.

In ServiceNav, building a user service is based on 3 key elements:

  • hosts (is my server turned on?)
  • unit services (is my database accessible?)
  • and finally, other user services (is my AD is available?)

These items must then be connected to make sense of the importance of each check, host and user service in the overarching user service. For this, there are two types of links: blocking or degrading. We must ask the question of each host, a service, a user service “what is the impact on the overall user service that we are constructing of each element?”.

If I build the payroll user service: Would the fact that my database is not accessible have the same impact as a hard drive running at 85% capacity? Would the fact that there are a few too many users connected to the application at the same time have the same impact as a Windows service (IIS for example) not running?

It is when these questions are asked and answered that the strength of user services is revealed!

Using degrading or blocking connections along with the construction of intermediate user services and complementary management rules to manage, for example, clusters, it is possible to represent almost any application from a business perspective based on key technical checks.
