✅ Real-time monitoring of physical disks
✅ Customizable thresholds for performance and alerting
✅ Actionable alerts and Remote Actions within role-based Monitor Viewsto resolve issues fast
✅ Visualize disk usage with charts and dashboard widgets

Example list of monitored Disks in a Monitor View.

Monitoring Features

Automatic Discovery
- The Nodinite Windows Server Monitoring Agent uses WMI to automatically discover your physical Disks. Sharing insights is easy within Nodinite using Monitor Views.
State Evaluation - Based on user-defined thresholds (fixed or percentage)
Category-based Monitoring - Organize different types of Disks; monitored Resources are grouped by Categories.

State Evaluation for Disks

Monitored Disks are displayed within Nodinite as Resources. For example, if you have 3 physical Disks, you will have 3 Resources in Nodinite.

The name of the Resources comes from the type of monitoring and volume label:
- Free space for C: => Free space C:\
- Free space for D: => Free space D:\
All monitored Disks belong to one of the following Categories:
|Category|Description|
|:---:|---|
|Disk|Ensure the Disk is operational and the free space is within user-defined monitoring thresholds|

The Application name is the Display Name from the configuration of the monitored Windows Server:

Example of Application naming pattern.

Each item (presented in Nodinite as a Resource), is evaluated with a state (OK, Warning, Error, Unavailable).

From within Nodinite, you can reconfigure the state evaluation on Resource level using the Expected State feature.

Note
Depending on the user-defined synchronization interval set for the Windows Server Monitoring Agent, there might be a delay before Nodinite Web Client/Monitor Views reflects the change. Click the Sync All button (or use the dropdown for individual agent selection) to force Nodinite to request a resynchronization.

Monitoring Disks

For each Disk, the monitored state evaluates as described in the table below:

	State	Status	Description	Actions
Unavailable	Service not available	Service not available	If the server can't be reached and evaluated either due to network or security-related problems, or if the specific Disk does not exist	Review prerequisites
Error	Error state raised	Error state raised	The Disk has too low free disk	Disk Chart, Edit
Warning	Warning state raised	Warning state raised	The Disk has too low free disk	Disk Chart, Edit
OK	Online	Online	The Disk is accessible and is within user-defined monitoring thresholds	Disk Chart, Edit
