- New host page enabled for easy access to the data
Activation and setup
After adding this extension to your environment, you also need to enable data collection in settings either at the host or host group level. The settings name is Disk Analytics Extension.
Once data collection is enabled on the target Linux hosts, you can view key metrics for all local disk instances and further inspect any of the disk instances on the selected hosts using the new host page.
The classic host page does not display this information, but the information is also available using Data Explorer.
Feature sets
When activating your extension using monitoring configuration, you can limit monitoring to one of the feature sets. To work properly the extension has to collect at least one metric after the activation.
In highly segmented networks, feature sets can reflect the segments of your environment. Then, when you create a monitoring configuration, you can select a feature set and a corresponding ActiveGate group that can connect to this particular segment.
All metrics that aren't categorized into any feature set are considered to be the default and are always reported.
A metric inherits the feature set of a subgroup, which in turn inherits the feature set of a group. Also, the feature set defined on the metric level overrides the feature set defined on the subgroup level, which in turn overrides the feature set defined on the group level.
