User activity / Idle time

[mika]

Is it possible to monitor user activity simple way? Ie. when was the last time user used keyboard or clicked something. Currently our software monitors only who are logged in but it doesn't tell us if user is actually doing anything or if user is only idling. Is there some common event(s) sent to server when user is active and if there is, what is the correct way to handle those event(s)?

 

I know I can code system that updates database every time user actually does something, but that is not really an option because it would be time consuming to cover whole software for user activity and there would be bound to be gaps.

 

This is not crucial to us, but it would certainly be helpful.

Hi,

 

Here is pure JavaScript way to track the idle time and when it reach certain limit do some action, you can modify accordingly and use:

var IDLE_TIMEOUT = 60; //seconds
var _idleSecondsCounter = 0;
document.onclick = function() {
    _idleSecondsCounter = 0;
};
document.onmousemove = function() {
    _idleSecondsCounter = 0;
};
document.onkeypress = function() {
    _idleSecondsCounter = 0;
};
window.setInterval(CheckIdleTime, 1000);

function CheckIdleTime() {
    _idleSecondsCounter++;
    var oPanel = document.getElementById("SecondsUntilExpire");
    if (oPanel)
        oPanel.innerHTML = (IDLE_TIMEOUT - _idleSecondsCounter) + "";
    if (_idleSecondsCounter >= IDLE_TIMEOUT) {
        alert("Time expired!");
        document.location.href = "logout.html";
    }
}

This seems quite easy to integrate to our software Thank you!

Hi Delphi Developer!

How I can Integrate this code with UniEvents?

Thanks - Regards

Hi!

 

For example:

 

1. MainForm.Script:

var IDLE_TIMEOUT = 60; //seconds
var _idleSecondsCounter = 0;
document.onclick = function() {
    _idleSecondsCounter = 0;
};
document.onmousemove = function() {
    _idleSecondsCounter = 0;
};
document.onkeypress = function() {
    _idleSecondsCounter = 0;
};
window.setInterval(CheckIdleTime, 1000);

function CheckIdleTime() {
    _idleSecondsCounter++;
    var oPanel = document.getElementById("SecondsUntilExpire");
    if (oPanel)
        oPanel.innerHTML = (IDLE_TIMEOUT - _idleSecondsCounter) + "";
    if (_idleSecondsCounter >= IDLE_TIMEOUT) {
        //alert("Time expired!");
        //document.location.href = "logout.html";
        ajaxRequest(MainForm.form, '_idle_timeout', []);
    }
}

2. MainForm->onAjaxEvent:

procedure TMainForm.UniFormAjaxEvent(Sender: TComponent; EventName: string;
  Params: TUniStrings);
begin
  if EventName = '_idle_timeout' then
  begin
    // your logic
    ShowMessage('idle_timeout');
  end;
end;

Best regards.
