For monitoring up/down status’ for core Cisco routers/switches my idea is to monitor snmp response and ping, but I don’t want to get 2 alerts from 1 device if it were to go down.<o:p></o:p><o:p> </o:p>So can I get ping or snmp alerts if they go down individually and only one alert if the device is down hard? What other services do you recommend monitoring for up/down status besides ping?<o:p></o:p><o:p> </o:p>Or is ping sufficient enough in your opinion? I may configure text alerts only on ping and maybe just email alerts for snmp, or no alerts for snmp. I like seeing uptime in Nagios though, it makes it easy to see if any devices have just rebooted after an event.<o:p></o:p><o:p> </o:p>I continue to research every day but I am interested in your thoughts and opinions if you’d like to share.<o:p></o:p><o:p> </o:p>Oh, can I integrate Nagios with my Cacti?

I have a fresh install of Debian stable (squeeze) with apt-get installed Webmin, ssh, apache2, and Nagios 3.2.1, nagiosql, and whatever dependencies. I am trying to setup monitoring of our core Cisco routers and switches. I have configured 2 services, ping and uptime. Ping works great of course but I can’t get a valid response from check_snmp for uptime. Here’s the command I’ve tried from the command line:<o:p></o:p><o:p> </o:p>root@atcdeb01:/# /usr/lib/nagios/plugins/check_snmp -H x.x.x.x -C public -o sysUpTime.0<o:p></o:p>no output, it just hangs<o:p></o:p><o:p> </o:p>I’ve also tried<o:p></o:p><o:p> </o:p>root@atcdeb01:/# /usr/bin/snmpget -v2c -c public x.x.x.x sysUpTime.0<o:p></o:p>sysUpTime.0: Unknown Object Identifier (Sub-id not found: (top) -> sysUpTime)<o:p></o:p><o:p> </o:p>Obviously with the correct IP and community string<o:p></o:p><o:p> </o:p>If I try this I get:<o:p></o:p><o:p> </o:p>root@atcdeb01:/# /usr/bin/snmpget -v2c -c public x.x.x.x 1.3.6.1.2.1.1.3.0<o:p></o:p>iso.3.6.1.2.1.1.3.0 = Timeticks: (447923619) 51 days, 20:13:56.19<o:p></o:p><o:p> </o:p>So using OID names aren’t working. I’ve researched with not much luck.<o:p></o:p><o:p> </o:p>From here and various other sites I’ve tried…<o:p></o:p><a href="http://wiki.debian.org/SNMP">http://wiki.debian.org/SNMP</a><o:p></o:p><o:p> </o:p>Added “deb <a href="http://ftp.us.debian.org/debian">http://ftp.us.debian.org/debian</a> squeeze main contrib non-free” to /etc/apt/sources.list<o:p></o:p><o:p> </o:p>apt-get update<o:p></o:p><o:p> </o:p><pre>Then apt-get install snmp-mibs-downloader<o:p></o:p></pre><pre><o:p> </o:p></pre><pre>Then “download-mibs”.
