How to log when a event is triggered

[JuanUil]

Hi all,

I would like to log when an event is triggered over a longer period of time.
Can I write the log to a file on my raspberry?
And if yes, does anybody have an example in LUA script how to do this?

Many thnx in advance for your help

Don't know about lua, in PHP it's quite easy. I made a function for it:

Code: Select all

$LogFile = '/var/log/floorplan.log';
function logwrite($msg,$msg2 = NULL) {
	global $LogFile;
	$time    = microtime(true);
	$dFormat = "Y-m-d H:i:s";
	$mSecs   =  $time - floor($time);
	$mSecs   =  substr(number_format($mSecs,3),1);
	$fp = fopen($LogFile,"a+");
	fwrite($fp, sprintf("%s%s %s %s\r\n", date($dFormat), $mSecs, $msg, $msg2));
	fclose($fp);
}

Example:
//Example:
logwrite('Switch '.$idx.' '.$name.' '.$cmd.' by '.$user.' = '.$reply);
writes something like "2015-12-23 17:33:01.657 Switch 26 TV On by Tobi = OK"

Any print() statement output from the lua event scripts is logged in /var/log/domoticz.log (assuming you have that active)

Tnx for your quick reply.
I really don't know anything about PHP but this is exactly what I need.
If anybody knows how to translate this in LUA I would be verry, verry grateful!!

How can I make that active Jos?

[Egregius]

Logfile options are set in /etc/init.d/domoticz.sh (domoticz startup script).

[JuanUil]

And what do I need to change there?

[albaga]

On domoticz.sh file, will have a line that says:
DAEMON_ARGS="-daemon -www 8080 -sslwww 443"

Replace it by this:
DAEMON_ARGS="-daemon -www 8080 -sslwww 443 -log /tmp/domoticz.txt"


I think it will work well.

This is what I have from the standard distribution image:

Code: Select all

DAEMON_ARGS="-daemon -www 8080 -sslwww 443 -log /var/log/domoticz.log"
