Monitoring Memory usage

Learn how to monitor the utilization of your physical Memory and get alerts when the amount/percentage free is too low

This page describes what's being monitored for physical Memory in Nodinite, using one or more role-based Monitor Views. Nodinite monitors the state, based on user-defined thresholds, either global or specific. For managing the Memory, remote commands are available as Actions. These help you swiftly manage reported problems. The implemented Remote Actions are further detailed on this page.

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 - To help you sort out the different types of resources, the monitored Resources are grouped by Categories

Memory State evaluation

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

  • The name of the Resources are hardcoded:

    • Available memory

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

    Category Description
    Memory Make sure the 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:
    Application Path Example

Each item (presented in Nodinite as a Resource) and 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 upon the change. Click the Sync All button (or on the dropdown for individual agent selection) to force Nodinite to request a resynchronization request.
