Dashboard

The following dashboard gives you an overview of the Memory usage on the cluster.

The Dashboard is divided into 4 sections described below:

Notifications

3 types of Notifications are displayed:

'See All notifications' allows you to view all notifications.

Used space: Memory used (Indexes & Dictionaries) of loaded indexes.
Unloaded index: Memory used (Indexes & Dictionaries) of unloaded indexes.
Maximum Heap before Memory low: Memory allocated for the indexima service - minus a buffer memory space.
Maximum Heap: Memory allocated for the indexima service.

Recommendation

Used Space + Unloaded Index should represent less than half of the Maximum Heap before Memory is low.

The other half is dedicated to SELECT or LOAD queries memory consumption.

As you can see, Memory usage is split into Index and Dictionaries size.
