Even 100 pages in 1 directory are analyzed, and all except for that is gathered by “others”. Can I more pages analyze?
yes, see: After the top 500 or top 1000 rows, Piwik automatically groups pages, keywords, websites, etc. under the label "Others"; How do I force Piwik to not limit the data? - Analytics Platform - Matomo
One directory of My web is more than 1000 pages It works fine. (Forgive my poor English…)
