Hello.
I have a perfomance problem, but my english very bad.
I have a high traffic piwik (100000+ page/action per day). I have 3 piwik node: two node only aggregation data and other one node is web interface and i have a separate server gor mysql database.I need help. Today i have a frezees in my piwik web interface that i haven’t before. But i can’t describe it in english.
.
Who can speek russian and may help me?
P.S. my gtalk is simplebox66@gmail.com
I trying to describe my problem using screenhots.Maybe anybody will understand me.
First of all, I discribe my system:
I have two vm with 8Gb memory and 4 CPUs (Intel® Xeon® CPU E5-2670 0 @ 2.60GHz). On those vm runs a nginx+httpd. Those vm work with only track code (piwik.js and piwik.php). Nginx config is
location /piwik.js {
proxy_pass http://local;
}
location /piwik.php {
proxy_pass http://local;
}
I called those vm - “aggregators” and I have separate server with nginx, which balance traffic between aggregators. So i collect users data.
Also, I have vm with 8Gb memory and 4 CPUs (Intel® Xeon® CPU E5-2670 0 @ 2.60GHz). I called this - “data viewer”. On this one runs a nginx+httpd. This vm is needed to work with a piwik web interface.
I have a hardware server with 32Gb memory and 16 CPUs (Intel® Xeon® CPU E5620 @ 2.40GHz). On this server runs a mysql database.
I use the following software version:
CentOS release 6.7 (Final)
nginx version: nginx/1.8.0
Server version: Apache/2.2.15
mysql 5.1.73
php 5.5.29
piwik 2.14.3
The database size: 11Gb. I track 100000 page per day. I have 12 users on piwik web interface. “Archive reports when viewed from the browser” is disable, “Archive reports at most every X seconds” - 1800.
I use auto-archiving - “*/30 * * * * /usr/bin/php /var/www/html/<“data viewer”>/html/console core:archive --url=https://<“data viewer”>”.
Secondly, I discribe my first and main problem:
When user want to use segments view, he have a problem. Please look at screenshot 1,2,3 and you understand that I said. I say about error (screenshot 3) and and that the requests are processed for a long time. At this time mysql base is have a problem:
rise MySQL threads connected, rise cpu usage.
My second problem:
Look at screenshot 4,5,6 - it`s normally work. But when I load segments view, the button “view visitor profile” is not working.( look at the screenshot 7)
upd. I attached next screenshots
and the last screenshoot
Hello

second problem.
please only report one problem per thread or it gets confusing
Ok, @matt.
What you think about my frst/main problem?
Do you have any resolving? Or I must create a new topic about my main problem?
I find Very slow SQL queries when archiving a segment for an unknown action · Issue #8102 · matomo-org/piwik · GitHub , but i don’t understand does this solve my problem or not? Is this resolving my problem, that may you describe what I need do, because I don’t understand.
P.S. sorry for my bad English
