Create Tiers
You can create hierarchical tiers that specify the importance of your applications.
Click Inventory and select Tier from the Applications group.
The list of existing tiers is displayed: the four IO-defined tiers are Tier 0, 1, 2, and 3.
Click New and select Tier from the Applications menu.
The create entity screen is displayed.
You can create a brand-new tier or clone an existing tier.
You can also specify the Tier Ranking.
You can add Custom and System Property / Value pairs to the tier, which can then be used as identifying factors: for example Server / Chicago.
You can Add Applications to the tier.
Click Save.
