Logs are very useful as it monitors and provides important information about the program such as activities, executions, real-time data etc.<\/p>\n

Log.io is a log management tool<\/a> that monitors the system and provides real-time information on the system logs. It is a simple and effective application built on top of Node.js<\/a>\u00a0<\/strong>and Socket.io<\/strong>. Log.io is not used to store, archive or index log messages, or provide information on the historical or aggregate analysis.<\/p>\n

\nNow, let’s install Log.io and see how it works. Before the installation, let’s first understand the architecture of Log.io<\/p>\n

\"logio-architecture\"<\/p>\n

Harvesters<\/strong>\u00a0monitors the log files and look for new changes, \u00a0sends messages about the new log files to the server<\/strong>, which are then broadcasted to the\u00a0web browsers<\/strong>. Log messages are tagged with a stream, node, and log level information based on user configuration.<\/p>\n

Log.io has no persistence layer i.e. file changes are informed via inotify, and log messages flow from harvester to server to web\u00a0browser via TCP and Socket.io, respectively.<\/p>\n

Steps to install and getting started with Log.io<\/strong><\/p>\n

    \n
  1. Install latest version of\u00a0Node.js<\/a><\/strong>\n

    [js]
    \n\tsudo add-apt-repository ppa:chris-lea\/node
    \n\tsudo apt-get update
    \n\tsudo apt-get install nodejs
    \n[\/js]<\/p>\n<\/li>\n

  2. Install rpm<\/strong>\n

    [js]
    \ncurl -sL https:\/\/deb.nodesource.com\/setup_6.x | sudo -E bash –
    \n[\/js]<\/p>\n<\/li>\n

  3. Installing Log.io<\/strong>\n

    [js]
    \n\tsudo npm config set unsafe-perm true
    \n\tsudo npm install -g –prefix=\/usr\/local log.io
    \n[\/js]<\/p>\n<\/li>\n

  4. All the files will be stored inside \/usr\/local\/lib\/node_modules\/log.io<\/li>\n
  5. Now going inside ~\/.log.io directory\n
