Monitor Cisco Uptime

[Will Bashlor]

Thanks Jörg,

 

Thanks for the check uptime plugin script. I did get that plugin to work but it doesn’t work with the “-c mycommunity” switch, it still uses the default “public” community. The host switch “-h x.x.x.x” works fine. Maybe I’m doing something wrong?

 

In Nagios, the output shows:

 

OK - 199.180.176.2: sysUpTime is 68 days, 22:48:07.08

 

How can I get it to simply show:

 

68 days, 22:48:07.08

 

That would be much easier to scan a list in my uptime service group.

 

I’ll have to use a test switch and play with the alerts. Thanks again.

 

-Will

	The thought in my mind for querying uptime via snmp had 2 purposes, 1.) to (possibly) alert on no snmp response, and 2.) To display uptime in a list format on Nagios for my network engineers/techs to view.

	 

	I like the idea of alerting on uptime < 1 day. But wouldn’t the reply need to be in a numbered time format only? I guess my mind is in Cacti threshold plugin mode. For example:

	 

	If the snmp respond replies with 4579200 in seconds (53 days), and I want to alert on uptime less than 1 day then my alert value would be <86400, correct? If this is true how can this be done when the response is:

	 

	“iso.3.6.1.2.1.1.3.0 = Timeticks: (447923619) 51 days, 20:13:56.19”

	 

	Or can I alert based on 447923619 only? It appears the 447923619 is seconds with the last 2 digits being hundredths. Secondly, how can I simply display “51 days, 20:13:56.19” In Nagios? I know these are basic questions, I have a lot to learn and will continue to research every day.

	 

	We have ssh only enabled for obvious security reasons, so that would work as well for monitoring device vitals.

	 

	I’m still interested in what other Network Managers as myself are using, services wise to monitor critical core equipment vitals other than ping, if anyone else would like to share.

	 

	Today we are using an older version of whatsup with a little over 1000 devices/services (includes CPE) with ping only. I’m looking to Nagios as a possible future replacement. Love it so far, just a bit of a learning curve. NagiosQL helps me a lot with config files.

	 

	Thanks for the response.

	>>>What other services do you recommend monitoring for up/down status besides ping?

	You could also do ssh or even telnet, if you have them enabled.

	 

	You did not ask, but a comment on uptime. You can use it to detect router bounces, detecting rogue reloads or perhaps system crashes. I have it to go to critical whenever the uptime is below X minutes, and email out. Network tests such as ping, snmp or ssh availability might miss a quick box's trip down, but uptime will always catch a reload.

	Hi list,

	 

	Well I’m not sure which of the steps below worked but it started working in Nagios and the check_snmp command works from cli. I’d still be interested in a guide or the correct steps I should have taken. I’m on a test vm now but will be reinstalling on a production vm later.

	 

	root at atcdeb01:~# /usr/lib/nagios/plugins/check_snmp -H x.x.x.x -C public -o sysUpTime.0

	SNMP OK - Timeticks: (448261008) 51 days, 21:10:10.08 |

	root at atcdeb01:~#

	 

	Now I’ve got to figure out a couple more things. Feel free to respond if you can help.

	 

	1.)    Even though ping and uptime show ok, the test Cisco host status went to “PENDING” in Nagios…?

	2.)    Not sure how to get rid of part of the response I don’t need for uptime. I only need “51 days, 21:10:10.08” under Status Information in Nagios

	 

	Another thing, I’m looking for advice. 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.

	 

	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?

	 

	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.

	 

	I continue to research every day but I am interested in your thoughts and opinions if you’d like to share.

	 

	Oh, can I integrate Nagios with my Cacti? Sorry for all the questions but will be very grateful for any responses.

	 

	Thanks all very much,

	 

	-Will

	Hi list,

	 

	I’ve searched to no avail, this is a basic question with hopefully a simple answer.

	 

	I’m a long time cacti user (windows), I know basic Linux knowledge, new to Nagios. 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:

	 

	root at atcdeb01:/# /usr/lib/nagios/plugins/check_snmp -H x.x.x.x -C public -o sysUpTime.0

	no output, it just hangs

	 

	I’ve also tried

	 

	root at atcdeb01:/# /usr/bin/snmpget -v2c -c public x.x.x.x sysUpTime.0

	sysUpTime.0: Unknown Object Identifier (Sub-id not found: (top) -> sysUpTime)

	 

	Obviously with the correct IP and community string

	 

	If I try this I get:

	 

	root at atcdeb01:/# /usr/bin/snmpget -v2c -c public x.x.x.x 1.3.6.1.2.1.1.3.0

	iso.3.6.1.2.1.1.3.0 = Timeticks: (447923619) 51 days, 20:13:56.19

	 

	So using OID names aren’t working. I’ve researched with not much luck.

	 

	From here and various other sites I’ve tried…

	http://wiki.debian.org/SNMP <http://wiki.debian.org/SNMP> 

	 

	Added “deb http://ftp.us.debian.org/debian <http://ftp.us.debian.org/debian>  squeeze main contrib non-free” to /etc/apt/sources.list

	 

	apt-get update

	 

	Then apt-get install snmp-mibs-downloader
	 
	Then “download-mibs”. Restart snmp.
	 
	All to no avail. What am I doing wrong? Is there a simple guide I can use so check_snmp works with oid names for Cisco and other devices?
	 
	Thanks for any help you can provide.
	 

	Best Regards,

	 

	-Will
