Piwik stops tracking on all websites without errors

Support & Bugs

Dear Community,

I´ve contacting you regarding an issue within our piwik installation.

We are using Piwik (currently Version is 2.16.1) on Centos 6 a couple of years.
We are tracking 7 public websites. Their total site views from jan 2016 until 25.7 are 6.2 millions.

Now we have the problem that since 25th July 2016 07:57 no further visitors on ALL websites are tracked.
The last update has been done on the 13th July. Since this date nothing has been changed and piwik still tracks unit 25th July. At this date nothing has been tracked any more.

There are no httpd and mysql error logs in /var/log/…
At the httpd access logs there you can see further access to our piwik installation. The Piwik URL (https://piwik.vor.at) is available from outside. Also piwik.php and piwik.js is available.

Our piwik website tracking code has not been changed…
Example:

Tracking code used inside Piwik:
script type=“text/javascript”>
var _paq = _paq || [];
_paq.push([“setDomains”, [".www.vor.at",".vor.at"]]);
_paq.push([‘trackPageView’]);
_paq.push([‘enableLinkTracking’]);
(function() {
var u="//piwik.vor.at/";
_paq.push([‘setTrackerUrl’, u+‘piwik.php’]);
_paq.push([‘setSiteId’, 1]);
var d=document, g=d.createElement(‘script’), s=d.getElementsByTagName(‘script’)[0];
g.type=‘text/javascript’; g.async=true; g.defer=true; g.src=u+‘piwik.js’; s.parentNode.insertBefore(g,s);
})();

Tracking code for one of our website you can find on https://www.vor.at:

Also we have checked the available disk space on the sever (maybe we ran out of space) but thats also not the problem. 25GB free space should be enough.

We have no clue why it stops working at all.

It would be great if you can help us.

Thank you!

Regards
Wilhelm

Hi there,

you can likely find out the problem by debugging the tracking calls as explained in: Tracking HTTP API: API Reference - Piwik Analytics - Developer Docs - v3

-> what do you find?

Hi,

I’m having a similiar issue that started when I updated to 2.16.1. I have since updated to 2.16.2-rc2, but the issue persists. I’ve tried enabling the debugging, but could not get any error messages. The weird thing is that the table piwik_log_link_visit_action continue to be updated with the visits, but table piwik_log_visit does not have any new rows since the update.

Can you check if your piwik_log_link_visit_action table has new rows since the update?

I’ve also enabled tracker debugging, but I get an empty response from the piwik.php. I cannot find any errors anywhere. I’m running on php7-fpm and nginx.

I reinstalled piwik completely and the problem seems to have been resolved. The actual problem was not found. Maybe the files were corrupted somehow.

Thanks for answer, we have found the reason for this issue. It was set a global IP-filter, that block all trackers. After disabling this filter all websites tracker works fine.
