VMmanager 6: Administrator guide



Nagios is an open source monitoring system. With Nagios, you can configure virtual machine (VM) monitoring in the platform.

Main components of Nagios:

  • server — the component for collecting and storing monitoring data, and alerting the administrator about problems with equipment. You can install Nagios server on a separate server or VM;
  • agent — the software installed on the VM. The agent collects monitoring data and transmits it to the server.

Nagios agents are installed on a VM using scripts from the ISPsystem repository. The scripts can be run both when the VM is being created and after it has been created. Read more in Running scripts on the VM.

Nagios uses an authorization token to connect to the agent. The value of this token must be entered when installing the agent and configuring Nagios server. A string of random characters can be used as a token.

Read more about Nagios in the official documentation.
