Monitor your infrastructure in real time using ssh to centralize a stream of log events

a drove of dragons


To install npm install proginoskes


The available configuration sections and options.

  1. `global`: Anything defined here is applied to all defined hosts 1. `host`: A host name defined here will work as a defined host 2. `port`: The default is 22 and is applied to all hosts unless explicitly defined 3. `username`: A username defined here will apply to all hosts 4. `password`: A password defined here will also apply to all hosts 5. `privateKey`: The path to a private ssh key (also applies to all defined hosts) 6. `logs`: An array of logs to monitor for all defined hosts
  2. `hosts`: The recommended method of including `host` definitions 1. `host`: The name or IP of machine to apply log monitoring streams 2. `port`: The SSH port for this particular host, uses global `port` option if omitted 3. `username`: The username for access, also uses the global `username` option if omitted 4. `password`: The password for access, again, uses the global `password` option if omitted 5. `privateKey`: The path to an SSH private key to use with this host. Will also use anything defined in global `privateKey` if omitted 6. `logs`: An array of logs to monitor for this host. Adds to anything defined in global `logs` array


var options = {
  global: {
    port: 22, //all hosts use this port unless defined
    username: 'root', //all hosts use this account unless defined
    privateKey: './path/to/global/privatekey', //all hosts use this key unless defined
    logs: [
      '/var/log/ufw.log' //all hosts stream these logs
  hosts: [
      host: 'host-1.example',
      privateKey: './path/to/host-1.example/privatekey',
      logs: [
      host: 'host-2.example',
      port: 2222,
      username: 'iamroot',
      privateKey: './path/to/host-2.example/privatekey',
      host: 'host-3.example',
      password: 'secret-sauce',
      logs: [


Once you have a good configuration with at least one defined host to monitor usage is easy.


var cherubum = require('proginoskes');

returned object

The returned object(s) are simple, but makes it easy to determine source.
