This is a convenient tool to monitor the system. The report shows a snapshot of your server statistics. The refresh rate for this snapshot is controlled by the Refresh Interval drop-down list in the upper righthand corner. The report contains the following sections: <ul><li>Server Health shows the basic server statistics, uptime, load, and anti-DDoS blocked IPs.</li> <li>Server lists current traffic throughput, connections, and requests statistics.</li> <li>Virtual Host shows request processing statuses and external application statuses for each virtual host.</li> <li>External Application lists the external applications currently running and their usage statistics. The CGI daemon process lscgid is always running as an external application.</li> </ul> Many of the rows in the Real-Time Statistics feature a graph icon. Clicking on this icon will open a graph of that row's statistics updated in real-time. In the Server section, next to Requests, there is a link labeled (Details). This link takes you to the Requests Snapshot, where you can view detailed information on which clients are making certain kinds of requests or which aspects of your site are bottlenecking. The fields in the blue area allow you to filter the snapshot to isolate certain parts of your server or look for clients that are performing certain actions.</p> </article> </div> <div class="helpitem"><article class="ls-helpitem"><div><header id="toggleDebugLog"><h3>Toggle Debug Logging<span class="ls-permlink"><a href="#toggleDebugLog"></a></span><span class="top"><a href="#top">⇑</a></span></h3></header></div><h4>Description</h4><p>Toggle Debug Logging toggles the value of <span class="tagl"><a href="ServGeneral_Help.html#log_debugLevel">Debug Level</a></span> between <span class="val">NONE</span> and <span class="val">HIGH</span>. As debug logging has an impact on performance and can fill up the hard drive quickly, so <span class="tagl"><a href="ServGeneral_Help.html#log_debugLevel">Debug Level</a></span> should usually be set to <span class="val">NONE</span> on a production server. This feature can be used instead to turn debug logging on and off quickly in order to debug a problem on a production server. Debug logging turned on or off in this way will not change anything shown in your server configurations.</p> <h4>Tips</h4><p><span title="Information" class="ls-icon-info"></span> <span class="tagl"><a href="#toggleDebugLog">Toggle Debug Logging</a></span> will only work if <span class="tagl"><a href="ServGeneral_Help.html#log_logLevel">Log Level</a></span> is set to <span class="val">DEBUG</span>. <span title="Performance" class="ls-icon-performance"></span> Important! Debug logging includes detailed information for each request and response. Active debug logging will severely degrade service performance and potentially saturate disk space in a very short time. This feature should only be used for a short period of time when trying to diagnose server issues.</p> <h4>See Also</h4><p class="ls-text-small"><span class="tagl"><a href="ServGeneral_Help.html#log_debugLevel">Debug Level</a></span>, <span class="tagl"><a href="ServGeneral_Help.html#log_logLevel">Log Level</a></span></p> </article> </div> <div class="helpitem"><article class="ls-helpitem"><div><header id="vermgr"><h3>Version Management<span class="ls-permlink"><a href="#vermgr"></a></span><span class="top"><a href="#top">⇑</a></span></h3></header></div><h4>Description</h4><p>Version Management (found by clicking on the the version number at the top of the page) is a convenient tool to manage LSWS versions.
