Log cannot be displayed #16

I'm currently running ZM in Version 1.31.0 from git clone 617cdd5fd385cc0dfd75b8aa56980ef42f492df7 on Ubuntu 16.04

For quite some time I have not been able to view the log messages over the web interface. Although all logs reside under /var/log/zm . Upon clicking the Log link on the ZM interface, the file web_php.log will be flooded with 7000-8000 lines of json formated data followed by the error message

unexpected error 5] at /usr/share/zoneminder/www/includes/functions.php line 1938.

Could the problem be related to a comma at the end of every json element? As far as I know it is not supposed to be there.

Find the log excerpt here: web_php.log

Are you actually storing logs in the db? That is what the log view shows. Not the contents of /var/log/zm/

The logs view works for me using current master.

Line 1938 of functions.php has to do with X10 commands. Are you using the X10 code?

Your web_php.log contains bad characters (non-utf-8) which cannot be decoded. This is the core of the problem. Ideally zm would strip them out from the logs before sending. I may have to look into that.

I think so. The link used to work. I have not used it for a few weeks. So I do not know when ist stopped working. I recall that it has failed before for a day or two and then suddenly worked again. During that time I had not installed an update for ZM.

Line 1938 of functions.php has to do with X10 commands. Are you using the X10 code?

Not that I am aware of. I am using a POE Camera. X10 is a powerline protocol, right?

Today was the first time I was able to see the Log ever since I created the issue. I'm not saying it's gone for good, but I will keep a closer look...

edit: I'm at commit 617cdd5fd385cc0dfd75b8aa56980ef42f492df7

I'd say its safe to close the issue. Displaying the log has been working for the last couple of months.

connortechnology commented 6 years ago

The log is unusable if you have a lot of log entries. It works great if you only have a few.

Rayn0r commented 6 years ago

So then I'll re-open the issue...
