With piped logs enabled in Apache HTTPS traffic is still put to access_log.processed during statistics calculation

Symptoms

1. In Plesk HTTPS web statistics is not calculated but for HTTP it is updated regularly at Domains > example.com > Web Statistics Web Statistics SSL/TLS.

2. Piped logs option is enabled in Tools & Settings > Apache Web Server.

3. After the statistics calculation for a domain, the file access_ssl_log.webstat is empty:

   # ls -l /var/www/vhosts/system/example.com/logs/access_ssl_log.webstat
   -rw——-. 2 root root 0 Jun 22 04:21 access_ssl_log.webstat

Cause

It is a Plesk bug with ID PPPM-8252, which is planned to be fixed in future product updates.

With Piped logs option enabled, both HTTPS and HTTP requests are logged in the file /var/www/vhosts/system/example.com/logs/access_log instead of being separated between access_log and access_ssl_log. As a result, webstat data is counted as if there is only HTTP traffic on a server.

Resolution

Until the bug is fixed, Piped Logs may be disabled in Tools & Settings > Apache Web Server. In this case, all future webstat data will be counted correctly, but it will not be possible to re-calculate already generated traffic and move it from HTTP to HTTPS.

If there is a need of having Piped Logs enabled on a server use the following workaround:

1. Connect to the server using SSH.

2. Create a directory for the custom virtual hosts configuration templates:

   # mkdir /usr/local/psa/admin/conf/templates/custom/

3. Copy the default template to that directory:

   # cp -a /usr/local/psa/admin/conf/templates/default/server.php /usr/local/psa/admin/conf/templates/custom/

4. Open the file /usr/local/psa/admin/conf/templates/custom/server.php in the text editor and change the following lines:

   BEFORE:

   <?php if ($VAR->server->webserver->apache- >pipelogEnabled): ?>
   CustomLog "|<?php echo $VAR->server->productRootDir ? >/admin/sbin/pipelog <?php echo $VAR->server->webserver->httpsPort ?>" plesklog
   <?php endif; ?>

   AFTER:

   <?php if ($VAR->server->webserver->apache->pipelogEnabled): ?>
   CustomLog "|<?php echo $VAR->server->productRootDir ?>/admin/sbin/pipelog 443" plesklog
   <?php endif; ?

5. Reconfigure the web server configuration:

   # plesk repair web
