A Tier is a group of servers that are performing the same or similar functions using the same port or group of ports. These can be set on a per-map basis or for every map. This allows a simple view of the map to understand your infrastructure, allowing you to clearly understand what is going on. They are being discovered based on the ports.
To see all your tiers, you go to Inventory > Tier Types. When clicking a Tier grouping, the server type list screen opens and shows the list of all servers participating in this group, based on the ports that these servers listen to. Any server that is not specifically part of a Tier will be shown in the Other grouping.
Creating and Editing a Tier
There are two ways to create and edit tiers. This can be done for all Application Maps or on a per-map basis.
Global Tiers
A Global Tier is applied to all maps and can be edited from the Inventory screen. This allows you granular control of what your tiers represent. To create a Tier
To edit a Tier, you click on the pencil icon. You will then be shown the same screen for both. When editing the tier, you will see the name, default ports, color, and icon, which can all be changed. Additionally, when on the Inventory > Tier Types screen, you can select one or more servers and either remove them from the tier or select Move To to place the selected servers in a new tier.
Application Map Tiers
From an Application Map, you can amend the tiers for the specific map you are looking at. To do this, you select the map, then right-click on a Tier and select Edit Tiers. From here, you can drag and drop servers that are on the specific map between the tiers, or create a new Tier. From here, you have two options -
Update This Map - applies the changes and new tiers only to the current map.
Set Changes As Default - apply all changes as default for the servers in this map. This will affect all maps that do not have a tier set manually for the relevant server.
Reset All - Discard current changes.
