Monitor the status of a port via snmp "ifOperStatus"

Post by ukzerosniper »

Hi Guys,

I have asked this question on the tail end of another thread which I fear may be dead, therefore I have decided to post a new thread with the question too.

I am trying to figure out how to monitor the status of links on our network. I have created a test map with only one link in it.

The idea as suggested in another post is to monitor the "ifOperStatus" of the ethernet port on the switches.

Currently, the best I can get is that it always says the link is down.

Below is the code I have used for the map and below that is an SNMP walk of the switch in question. The port im interested in on this example is port 4.

Thanks for any help anyone can provide.

Code: Select all

KEYPOS DEFAULT 1755 96 Traffic Load
KEYTEXTCOLOR 0 0 0
KEYOUTLINECOLOR 0 0 0
KEYBGCOLOR 255 255 255
BGCOLOR 255 255 255
TITLECOLOR 0 0 0
TIMECOLOR 0 0 0
SCALE DEFAULT 0 0 255 0 0 
SCALE DEFAULT 0 100 0 240 0 

SET key_hidezero_DEFAULT 1

# End of global section

# TEMPLATE-only NODEs:
NODE DEFAULT
	MAXVALUE 100

# TEMPLATE-only LINKs:
LINK DEFAULT
	BANDWIDTH 100M

# regular NODEs:

	ICON images/aaaSwitchSmall.png
	POSITION 191 198

NODE trswitch
	LABEL TR Switch
	ICON images/aaaSwitchSmall.png
	POSITION 547 198

# regular LINKs:
LINK mcswitch-trswitch
	SET ip 172.16.172.89
	SET interface 4
	TARGET snmp:{map:community}:{link:this:172.16.172.89}:.1.3.6.1.2.1.2.2.1.8{link:this:interface 4}:-
	NODES mcswitch trswitch

Looks like you've got a few things wrong in your TARGET line
TARGET snmp:{map:community}:{link:this:172.16.172.89}:.1.3.6.1.2.1.2.2.1.8{link:this:interface 4}:-
{map:community} - I don't see this defined anywhere. Just enter the community string here.
{link:this:172.16.172.89} - You don't have any variable 172.16.172.89 defined. You probably want to use {link:this:ip}
{link:this:interface 4} - No variable "interface 4" defined. Just use {link:this:interface}

So, your end result should be something like (assuming a community string of public)

Code: Select all

TARGET snmp:public:{link:this:ip}:.1.3.6.1.2.1.2.2.1.8.{link:this:interface}:-
edit: Typo, forgot about the missing . before {link:this:interface}. You were missing that as well :)
