I need an application that, when running on a machine (the controller), can monitor basic system resources and network connectivity for about 20 Windows servers/clients (the nodes), all in the same local network.

The nodes should be agentless, i.e. no dedicated client/agent should be installed on them.

If necessary, it's acceptable to manually configure any relevant service/permission on a node, as long as it's something that comes with the the OS by default (e.g. PowerShell). Installation of a Java virtual machine is also acceptable.

Supported operating systems for the controller and the nodes:

  • Windows 8.1
  • Windows Server 2012 R2
  • Windows 10

Some other must-have requirements:

  • It's free and open-source
  • The following data is collected every X seconds:

    • IP connectivity (ping)
    • Uptime/Downtime
    • CPU usage
    • Physical and virtual memory usage
    • Disk usage
  • The controller requires a minimal configuration/setup, possibly without the need of prerequisites such as a full-fledged RDBMS or a full-fledged Web Server (e.g. MySQL, Apache).
  • The data is saved on the filesystem or on a SQLite database, on the controller.

The nice-to-have requirements:

  • The controller can send e-mails to alert predefined users about particular events (e.g. lost of network connectivity)
  • The real-time and/or historical data can be displayed remotely on a browser, from a few users on their own machines
  • It has ready-to-use plugins to monitor other system resources and/or can be extended by writing custom plugins

Before writing my own, I was wondering if something with these features already exists.

I suppose, 10-Strike LANState Pro complies with the most of the required things (visit link).

IP connectivity (ping)
CPU usage
Physical and virtual memory usage
Disk usage

In addition, it discoveries and builds a network map.

However, it is not free and open source.

  • open-source is listed as a "must-have".
