The ICC is the reflection of the accommodation capacity of your architecture.
It is interesting to follow its evolution, to follow its tendances. This indicator doesn’t need to be followed every minutes, but better weeks after weeks, months after months by following particularly the impact of a code deployment on your ICC. If the ICC increases, it means that your accommodation capacity has decreased and vice versa.
Ex: If your ICC has been multiplied by 2, your accommodation capacity of your site has been divided by 2 at the same time ! This should require your attention !
