Hi Sam, I'm curious, why do you need to know if people are logged in? Thanks -Vincent On Oct 9, 2008, at 11:07 PM, Samuel Lee wrote:

For that, you can do: #foreach($userName in $xwiki.search("select distinct lock.userName from XWikiLock as lock")) $userName #end This is a crude example, as it will select also stale, uncleaned locks. You should try to integrate a WHERE condition on the lock.date property. As about users browsing the wiki without editing, you can't do that without statistics. The way authentication works now, there is no information on the server about logged in users, as each request validates the user (slower, but safer). You could instead do the following: Edit the logging configuration (as in http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Logging ) and add the following rule: log4j.logger.com.xpn.xwiki.user.impl.xwiki.XWikiAuthServiceImpl=info Now you will see all the authenticated users in the log, you just need to write a nice shell script that selects what you want, for example: cat xwiki.log | grep "is authentified" | tail -200 | cut '-d[' -f1,3 | cut -c1-19,70- | tail -1000 displays the last 1000 authentication lines, along with the date, cat xwiki.log | grep "is authentified" | cut -d- -f5 | cut '-d ' -f 3 | tail -1000 | sort | uniq displays the users from the last 1000 requests. -- Sergiu Dumitriu http://purl.org/net/sergiu/
