You can then alert on it when values of uptime are less than whatever suits your check frequency and max check attempts values eg 30 minutes. How you actually check is going to be dependent on the OS of the device For Windows servers I use check_wmi_plus.pl -m checkuptime This particular plugin also provides performance data and I get a nice graph like this - <img src="cid:part1.09070209.06000406@edcint.co.nz" alt=""> I also do that same thing (using other plugins) for linux, wireless access points etc I imagine that SNMP probably can get at the uptime values for various devices also. <blockquote cite="mid:69f8f8e31333b459ad50fb6fe844ef8e.squirrel@webmail.stinkweasel.net" type="cite"> <div class="moz-signature"> <a href="http://www.smartmon.com.au">Smartmon System Monitoring</a> <a href="http://www.smartmon.com.au">www.smartmon.com.au</a> </div> </blockquote> </body> </html>
