Web statistics is not being generated/updated for websites hosted on the Linux Shared Hosting NG cluster.
The problem is resolved in POA 5.4.13, upgrade the installation to this or higher version.
In the meantime use the following solution - add the entry below as single line to the /etc/crontab file on all web servers in NG cluster:
15 0-23/3 * * * root /usr/local/pem/etc/web_cluster/isdirector.sh && /usr/local/pem/bin/logparser.sh >/dev/null 2>&1
The logparser.sh script which is responsible for web and FTP logs parsing and web statistics generating as well is not added to the /etc/crontab file on web server. As a result the logparser service does not work (just because the script is not being invoked periodically by cron) and web statistics is not being updated.
