Info

Two files are created in the working directory:

settings.json

At the moment the following variables are available:

• AgentPort (default 5000)
• LoggingEnabled (default true)
• LoggingDirectory (deafult "logs")
• DaemonMode (default false)
  If true is specified, the program will wait for the end signal (Ctrl+C or service magent stop)
• SaveHistorySeconds (default 2678400)
  Specifies for which period to store the history in the "history.dat" file in seconds.
  
• AutoSaveHistorySeconds
• AutoSaveHistoryEnabled
• MaxReturnHistoryItems
• TokenString

You can always create a corrected file with the settings using ./init.sh
All available variables will appear there.

history.dat

Monitor template:

You can create your own monitor.

namespace MonitoringAgent.Monitors
{
    [Monitor("test")]
    class TestMonitor : BaseMonitor
    {
        public override void Init()
        {
            Json.Your = 0;
            Json.Custom = "hello";
            Json.Data = true;
        }

        public override void Update()
        {
            ++Json.Your;
        }
    }
}

Usage exmaple (using jQuery)

var token = '917700A0CB394840992BF2142A92DDE7';
setInterval(function () {
  $.getJSON('localhost:5000/' + token, function (data) {
      console.log(data.test.Your);
      console.log(data.test.Custom);
      console.log(data.test.Data);
  });
