Monitoring a remote system running on Linux

Monitoring a remote system running on Linux is straightforward with MetricsHub. After identifying the linux connectors available to collect metrics about the OS, the network interfaces, or the server itself, you need to configure one or several monitoring protocols, typically:

• ssh to collect operating system-specific metrics and information about CPU, file system, memory, network interface, physical disk, process, etc.
• snmp or wbem to collect hardware information about the physical machine.

In the example below, we configure MetricsHub to monitor the remote machine dev-nvidia-01 running on Linux through the SSH protocol. We do not declare any specific connectors to let MetricsHub detect the most suitable ones and collect the metrics available.

Procedure

To monitor a remote machine running on Linux:

1. In the config/metricshub.yaml file, we configure the monitoring on a Linux machine through SSH:

       resources:
         dev-nvidia-01:
           attributes:
             host.name: dev-nvidia-01
             host.type: linux
   

2. Then, we configure the SSH protocol

           protocols:
             ssh:
               username: myusername
               password: mypassword
   

Here is the complete YAML configuration to be added to config/metricshub.yaml to monitor a remote machine running on Linux:

    resources:
      dev-nvidia-01:
        attributes:
          host.name: dev-nvidia-01
          host.type: linux
        protocols:
          ssh:
            username: myusername
            password: mypassword
