Date/time is added automatically, so you only need to supply event text. Create event scripts to log whichever info you need.
Code:function eventlog(text)
local max = 1000 -- max number of entries
-- add formatted date
text = os.date('%a %d/%m/%Y %T ') .. text
storage.exec('lpush', 'eventlog', text)
storage.exec('ltrim', 'eventlog', 0, max - 1)
end
To output the list to client side you can create an .lp page and display it in the visualization via iframe. Create a file called eventlog.lp and upload it to user folder via FTP. Set iframe URL to /user/eventlog.lp
Code:<?
require('apps')
items = storage.exec('lrange', 'eventlog', 0, 999)
?>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Event log</title>
<script src="/apps/js/jquery.js.gz"></script>
<link rel="stylesheet" href="/apps/css/bootstrap.css">
</head>
<body>
<script>
$(function() {
var items = <? json.write(items) ?>
, container = $('.container')
, header;
$.each(items, function(index, item) {
var chunks = item.split(' ')
, newheader = chunks.shift() + ' ' + chunks.shift();
// output data header each time it changes
if (newheader != header) {
header = newheader;
$('<h3></h3>').text(header).appendTo(container);
}
// output log entry
$('<p></p>').text(chunks.join(' ')).appendTo(container);
});
});
</script>
<div class="container"></div>
</body>
</html>
Note that newest items come on top of the list.

Hi. I would like to use this code, but i don't know where i should put this code:
Code:
function eventlog(text)
local max = 1000 -- max number of entries
-- add formatted date
text = os.date('%a %d/%m/%Y %T ') .. text
storage.exec('lpush', 'eventlog', text)
storage.exec('ltrim', 'eventlog', 0, max - 1)
