Service weather is one of ServiceNav's differentiating assets and a valuable "macro-supervision" tool.

But are you using it to its full potential?

Some reminders

A User Service is an aggregation of one or more :

  • Hosts
  • Services
  • Other user services

Service Weather (Supervision > Service Weather) presents user services through 4 states and 3 trends.

OK / deteriorated / out of order / unknown constant / up / down

Asking the right questions

Designing a service weather forecast is first of all a question of asking yourself the right ones questions :

  • What are the services provided by my infrastructure?
  • When are these services consumed (time slot)?
  • On which services do I need to measure availability and at what rate?

Once this reflection has been carried out, it then becomes possible to list all the equipment and unit services that make up its user service and to define time slots and a target availability rate.

If the complexity is still high, however, it is preferable to go down the tree and create other services, which will make up its main service.


The relationships between a User Service and its various components are of the "blocking" or "degrading" type. In order to determine which type is used, here again it is beneficial to ask the right questions:

If a component of my service is indispensable to its operation and cannot be duplicated by another component (AND relationship) -> blocking link 

If a component of my service  can be redundant by another component or is not essential to the minimum functioning of my service (OR relationship) -> degrading link

Exploiting the data

A correctly configured weather forecast is an asset, good reports and dashboards are even more so.

A dedicated dashboard: The weather map ("Weather services (map)")

This dashboard presents the list of user services, by site/by customer, on a map background.

It is particularly relevant in a multi-site context and also brings value in the case of technical interventions (by allowing a technician to reorganize his movements according to nearby breakdowns and their impact).

Other dashboards that integrate the User Services: the "User Services Dashboard", the "User Services Dashboard" and the "User Services Dashboard". MAP« the "Park monitoring by family", ...

A report with high added value: the availability report ("Availability Analysis")

The availability report is a real decision-making tool that can be used internally or with customers to demonstrate service quality or to identify areas for improvement. The availability report can be used to consult :

  • The TOP/FLOP of user services: which services are the most available over the period?
  • For each User Service :
    • total unavailability
    • per month: the evolution of the availability rate, the number of unavailabilities and their duration

These indicators allow ISD to :

  • Communicating to customers about the availability of services
  • Identify weak points and trigger corrective actions
