Hi, we use Matomo since a long time (archives date back til 2006 ), but today our mariadb database was crashed by Matomo .

From the DB dump (see below) there is a very long/cryptic SQL query, which seems to have been generated by core/RankingQuery / generateRankingQuery(…).
I’m not sure, if I need to adjust some Mariadb config parameters, or if this is really a bug. Can anybody help?

Here is the relevant mysqld.log part:

190218 12:11:58 [ERROR] mysqld got signal 11 ;
This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.

To report this bug, see https://mariadb.com/kb/en/reporting-bugs

We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.

Server version: 10.0.35-MariaDB
key_buffer_size=16777216
read_buffer_size=262144
max_used_connections=152
max_threads=153
thread_count=27
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 371914 K bytes of memory
Hope that’s ok; if not, decrease some variables in the equation.

I am experiencing an issue with an application that uses Matomo to track visits to a website, and also submit usage events to a different idsite in an app. It’s mildly complex, so I’ll describe a workflow to demonstrate my issue.

• User visits site, they are given a visitorId
• User clicks button in site to open a new widget on a window with a different domain. We pass the vistorId to the widget when the button is clicked.
• Upon widget completion, we request the data for the visitorId via the API, and perform actions on it.

What I have discovered is that, in the widget, the visitorId we pass from the main site to the widget, does not actually exist as a visitorId in the Matomo DB. This an intermittent issue.

Are there circumstances in which Matamo will create a visitorId and not save it?

Caveat: I am also using the same Piwik instance to track widget usage. This submits the usage events to a different idsite (same idsite for all widget instances). What I don’t know is if this potentially a factor, since I cannot reliably reproduce.

So after some reading i’m not sure if this is a bug or support question. I can’t find a way to segment visitors based on a url they have visited in a vist or in a previous visit.

e.g. my colleague asked to see all visitors who ever went through a certain category on our wordpress site, but when i choose to segment on a “action url” using the containing option then only the page url’s/ titles etc that specifically contained that url where returned not how many people came from say the home page to that category or went on to read other articles from that category. We wanted a segment so we could see all the location, refere info, broweser stats, etc, If it was a single page i would use the transistions option but no good. Preferably it would be great to see all url’s in all time so not just with in one visit.

There seems to be a few requests around this, and the events url option that was bought in. When i use the event url option i get no result at all!

If i had known this was needed I could have set a goal, but it looks like thers no way to do a goal that goesback in time

in the future i guess i could set up a custom dimension with code like:

_paq.push(['setCustomDimension', 3, 'catagory-slug']);

Any help or suggestions would be warmly recived, I presume i’m not the only one with this problem and at the moment it’s the one feature that our team needs but i can’t provide with matomo

I’ve implemented a solution to get our PayPal IPN notifications to report sales to Matomo Matomo 3.8.1 based on this guide: HowTo: Paypal tracking via IPN script

These are being tracked in the Goals->Campaigns report, but when you click through into the keywords these are being lost.

For example, I know that sales have come in through the keyword “msap-nl-18022019” as this was correctly recorded in the visitor log.

Any ideas?

Thanks,

Hello, my organisation needs to integrate the statistics of an old piwik installation to a different newer matomo installation. This newer version also contains statistics for different sites. The server for the old installation will be removed soon.
How do I bring the statistics from the old sites into the newer installation in order to have both the statistics for the old sites and the statistics for the new sites living togehter?

Hello!
Recently I have the problem that visits break up into several visits and are then counted multiple times in the stats.

See the attachted example. Piwik recognizes the page views (which are within seconds/minutes) as coming from the same visitor but counts them as separate visits.

visit.png715×697 31.8 KB

Does anyone know the reason why or what can be done about it? The site is running on wordpress and uses WP-Piwik to add the tracking code.

Thanks!

I face a weird issue:

i can’t use the visitConvertedGoalId segementation feature for another Goal. For example: I want to see, how many people have clicked the “final purchase” button in my shop and have achieved a certain Goal before?
To do so I open the “final purchase” Goal report, and set the segment to visitConvertedGoalId==1 for example.

It would be very helpful if someone can help me with this problem.
Big thanks in advance.
Best, Dustin

Hello,

I’m new to Matomo so this may be an easy fix that I have just overlooked. Initially I installed Matomo on a Ubuntu hyper-v on my local laptop and everything installed fine. I setup the website tracking, copied the javascript to the site I wanted to track and things worked as expected. Next I installed Matomo on a Windows server running IIS. Since there are other sites on this server I set it up on a different port. I setup the site I wanted to track (which is the same site I was tracking earlier) and now when I load the site in Firefox and Chrome I get an error: SyntaxError: expected expression, got ‘<’ and nothing is tracked. Is there a setting or something else that I need to check in order to get this to work?

Thanks,
Joseph

Motamo 7.2.14

Hello,
On one of my hosters motamo installation has heavy load times. Not only the result page but also diagnose page etc. load endless etc.
Diagnose reports: "Ihr Server nutzt ein NFS Dateisystem. Dies bedeutet, dass Matomo extrem langsam arbeitet, wenn Dateibasierte Sessions genutzt werden. "
But my Hoster says that this is obligatory by using virtual servers.

Could anyone have an idea to solve this?

Hello,
I discovered earlier today that the Opt-Out function is not working in the Edge Browser…

Yes, we do have a number of clients using Edge.

Appreciate your feedback.

Thanks,

We are using 3 analytics tracking systems on a set of 100 websites. Our internal tracking system and Google Analytics agrees pretty closely on sessions. Matomo is missing about 4,800 sessions out of 20,700 (23%). Of the missing sessions 98% are Safari browsers across devices. About 43% have the same UA:

Mozilla/5.0 (iPhone; CPU iPhone OS 12_1_4 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/12.0 Mobile/15E148 Safari/604.1

Perhaps stranger, not all users with Safari or even this User Agent are missed.

Safari users account for a sizable number of our orders and so simply ignoring their webtraffic is not an acceptable solution.

We are on the latest version of Matomo (just upgraded two weeks ago and the problem persists)
We have renamed the piwik.js file and server name
Do Not Track is off
We send a unique ID to all three systems so we can tell the individuals’ activity including that they hit a variety of web pages. There doesn’t appear to be a setup issue with the Matomo tracking script. I can see it firing in GTM
There are no javascript errors on the pages for these people.

Matomo is our system of record and we really need 100% of traffic tracked.

Hello,

Since this morning my matomo has only actualized the “visits in real time” but all other widgets have not shown actual analytics data. So data within matomo widgets show different data.
The server logfiles confirm that visitors and visits in motamo widgets are not counted reliably.

How can I fix this?

Thanks and Regards
