Parallels RAS components are monitored and logs are created containing relevant information. Logs are used by Parallels RAS support engineers to analyze possible issues with a Parallels RAS installation. As a Parallels RAS administrator you have the ability to set the log level for a specific component or multiple components. By default, the standard log level is used, which collects and saves only the essential information. A Parallels RAS support engineer can ask you to enable the extended or verbose log level when an additional information is required to analyze an issue.
To set the log level for a specific component/server, navigate to the page in the RAS Console where the components of that type are listed (e.g. RD Session hosts, VDI, Gateways, Publishing Agents), select a component and then click Tasks (or right-click) > Troubleshooting > Logging > Configure. This opens the Set Log Level dialog where you can choose a log level from the following:
Please note that to avoid degraded performance, extended and verbose logging should only be enabled for a limited time period (enough to collect the necessary information for analysis). You can set this time period using Reset to the standard level after option. The default value is 12 hours. In specific cases, a Parallels support engineer will advise you whether this time period should be set to a different value. Once this time period is over, the log level will be reset back to standard.
To retrieve a ZIP archive containing the log files, click Tasks (or right-click) > Troubleshooting > Logging > Retrieve and then specify a location where you want the file to be saved. The Clear item in the same context menu clears all logs.
Note that you can also set the log level on the Farm > <Site> > Settings > Global logging tab, where you can see RAS components of all types in one list. For more information, see Site settings.
