Replace localhost with $HOSTADDRESS$, and replace xxxxxx with your snmp community. Unfortunately, check_snmp doesn't seem to support having warning or critical thresholds, so unless snmpd is down, that will always return ok. You can use snmpget to get the raw timeticks: $ snmpget -Ovt -v2c -c xxxxx localhost .1.3.6.1.2.1.1.3.0 36207797 $ If you want a critical alert every time a box has rebooted, write a shell script that calls that snmpget command, passing in the host address and snmp community via the command line. Of course, that will throw an Unknown while the box is actually down (snmp can't tell if the host is down, or if you've passed the wrong snmp community.) If what you really want is to know when your box is down, use check_ssh: $ /usr/local/nagios/libexec/check_ssh localhost SSH OK - OpenSSH_5.1p1 FreeBSD-20080901 (protocol 2.0) $ That will throw a critical any time it can't connect, or if it can connect but the ssh version string isn't found. If you still want to use snmp traps, here's a link to some lovely documentation: <a class="moz-txt-link-freetext" href="http://snmptt.sourceforge.net/docs/snmptt.shtml">http://snmptt.sourceforge.net/docs/snmptt.shtml</a> There's even a section on integrating with Nagios, though I suggest you get some coffee and a snack and read the whole page. <pre class="moz-signature" cols="72">-- Mike Lindsey</pre> </body> </html>
