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');

cherubum.proginoskes(options, function(err, data) {

returned object

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