A possible way to Log User- and Page-Access to statsd is via the Event system - using Adaptavist's Scriptrunner for Confluence, se https://scriptrunner.adaptavist.com/latest/confluence/ConfluenceEventHandlers.html#_collecting_stats
Read Access Logging in Confluence for good reasons to log via the Event system.
The script is executed by an Event Handler in Confluence:
this executes this script for every PageViewEvent:
import com.atlassian.confluence.user.AuthenticatedUserThreadLocal
import com.atlassian.confluence.user.*;
import java.net.URL;
import java.net.URLEncoder;
import java.net.MalformedURLException;
import java.io.UnsupportedEncodingException;
import com.atlassian.confluence.pages.Page
import com.atlassian.confluence.pages.PageManager
import com.atlassian.confluence.spaces.Space
import com.atlassian.confluence.spaces.SpaceManager
import com.atlassian.sal.api.component.ComponentLocator
import com.atlassian.confluence.event.events.content.page.*
def spaceManager = ComponentLocator.getComponent(SpaceManager)
def pageManager = ComponentLocator.getComponent(PageManager)
String userName="Anonymous"
def currentUser = AuthenticatedUserThreadLocal.get()
if (currentUser)
{
userName=(String)currentUser.name
}
def event = event as PageEvent
String eventType=(String)event.toString()
eventType=eventType.replaceAll("com.atlassian.confluence.event.events.content.page.","")
eventType=eventType.substring(0, eventType.indexOf('@'))
eventType=eventType.replaceAll("Event","")
