View access and error logs for a site and configure log rotation.

Log Browser assists you in troubleshooting issues with your websites by parsing the web server logs and displaying relevant warnings and error messages in the Plesk interface.


On Linux, the information from the following log files is displayed by default:


Apache access (access_log). This log records all HTTP requests processed by the Apache web server.


Apache ssl access (access_ssl_log). This log records all HTTPS requests processed by the Apache web server.


Apache error (error_log). This log contains diagnostic information. It also records any errors that the Apache web server encounters in processing requests.


nginx access (proxy_access_log). This log records all HTTP requests processed by the nginx proxy web server.


nginx ssl access (proxy_access_ssl_log). This log records all HTTPS requests processed by the nginx proxy web server.


nginx error (proxy_error_log). This log contains diagnostic information. It also records any errors that the nginx proxy web server encounters in processing requests.


On Windows, the information from the IIS log is displayed. This log records all requests processed by the web server, both HTTP and HTTPS, as well as any errors that the web server encounters in


processing requests..


In addition, you can add any custom log file from you web site directory to track it in the Log Browser, as described below.


Access Log Browser


To access the Log Browser, go to Websites and Domains > Logs. You will be presented with a list of messages gathered from the logs. By default, the Log Browser displays messages present in the


monitored logs at the moment of opening. If you want to refresh the list with messages added after opening the Log Browser, click Refresh. Alternatively, if you want to have new messages continuously


added to the list, click Start real-time updates.


To select the logs from which you want to view messages, click the image 74882 icon, and select the desired logs from the menu.


Manage Log Files


To view all the messages in a log, go to Websites and Domains > Logs > click the image 74886 icon > Manage log files. The list of all tracked log files will be displayed.


Here you can click a log file name to view the file content directly in the Log Browser. You can click the image 74884 icon next to a log file to open it for viewing in a separate window, or the image 74885


icon to download it.


To save disk space, you can enable log rotation that is automatic compressing and/or deleting outdated website log files. To set up log rotation, go to Websites and Domains > Logs > click the image


74886 icon > Manage log files > Log Rotation.


You can delete log files that have been rotated (log files that have not yet been rotated cannot be removed).


Add a Custom Log File


You can add any custom log file from your web site directory to track its changes in the Log Browser. To do this, click the Add Custom Log button on the Manage Log Files page. The tree with your web


site folders will be displayed. Select the file that you want to add to the Log Browser and click OK.


If you no longer want to monitor this custom log file, click the image 75821 icon next to it. This does not remove the file from your file system, but simply removes the file from the list of files available in


the Log Browser.


You can also open a text file in the Log Browser directly from the File Manager, using the Open in Log Browser option.


When you open a log file from the File Manager in the Log Browser, it is not yet added to the list of logs viewed in the Log Browser on a permanent basis. To add the file to the Log Browser, click the Add


to Log Browser as Custom file button.
