However, I encountered a department which needs to shut down a monitored service during a maintenance window, and the servicecheck would restart it. Thus, I created a 'noservicecheck' item in the client-local.cfg process. Hope you find it useful enough to add to next PS version.</span></div><div class="gmail_default"><span style="font-family:verdana,sans-serif;font-size:small"><br></span></div><div class="gmail_default"><span style="font-family:verdana,sans-serif;font-size:small">Tim Williams</span></div><div class="gmail_default"><span style="font-family:verdana,sans-serif;font-size:small">Virginia Commonwealth University Computing Center</span></div><div class="gmail_default"><span style="font-family:verdana,sans-serif;font-size:small"><br></span></div><div class="gmail_default"><span style="font-family:verdana,sans-serif;font-size:small">Here is a section to add to the XymonPSClient.doc help file:</span></div><div class="gmail_default"><h2 style="margin:2pt 0in 0.0001pt;line-height:107%;break-after:avoid;font-size:13pt;font-family:"Calibri Light",sans-serif;color:rgb(46,116,181);font-weight:normal"><span lang="EN-GB">noservicecheck</span></h2>
