Monitoring Memory usage

Nodinite empowers you to proactively monitor and manage physical memory on your Windows Servers. This page explains how to set custom thresholds, receive real-time alerts, and leverage actionable insights to optimize performance and prevent outages.

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

Memory items as Resources
Example list with a monitored 'Memory' resource in a Monitor View.

Monitoring Features

  • Automatic Discovery
  • State Evaluation – Based on user-defined thresholds (fixed/percentage)
  • Category-based monitoring – Organize different types of resources; monitored Resources are grouped by Categories.

Memory State evaluation

Monitored Memory is displayed within Nodinite as a Resource. For example, if you have 3 Windows Servers being monitored, you will have 3 'Memory' resources in Nodinite.

  • The name of the Resources is hardcoded:

    • Available memory

  • The 'Memory' resource belongs to the following Category:

    Category Description
    Memory Ensure available memory is within user-defined monitoring thresholds

    Categories
    List of the Memory related category as a filter in a Monitor View.

  • 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.

The Memory Details page displays:

Memory Overview:

  • Total Memory - Total physical memory installed on the server
  • In Use - Currently allocated memory (GB and percentage)
  • Available - Currently free memory (GB and percentage)
  • Status - Current evaluation state (OK, Warning, Error, Unavailable)
  • Last Sample - Timestamp of most recent data collection

Memory Statistics:

  • Average Free - Mean available memory across sample window
  • Lowest Free - Minimum available memory recorded
  • Highest Free - Maximum available memory recorded
  • Sample Window - Time range for statistical analysis
  • Latest/Oldest Sample - Timestamps for data collection range

Monitoring Thresholds:

  • Monitoring Status - Whether memory monitoring is enabled or disabled
  • Evaluation Type - Percentage or Fixed (MB) threshold evaluation
  • Warning Threshold - Minimum available memory before warning alert
  • Error Threshold - Minimum available memory before error alert
  • Duration - How long thresholds must be exceeded before alerting

Installed DIMMs (Hardware):
