Nagios and SNMP
Nagios and SNMP
I have a nagios maching on my network that is monitoring my servers. I now need to use Nagios to accept and report SNMP traps. I have searched everywhere i know to search and have not found any articles on configureing Nagios to do this task. The hardware i am needing to monitor are Cisco 6509 Catalists.. the switches will send out SNMP messages but i can not figure out how to get Nagios to accept them. Any help is appreciated...

Re: Nagios and SNMP
There is a document on http://library.nagios.com/library/produ ... -nagios-xi that describes how to receive SNMP traps in Nagios XI, and the first two pages apply equally to Nagios Core. After that, you can analyze the source code of the wizard mentioned on page 3 to see the configuration format for creating a service to use them.
Re: Nagios and SNMP
Thanks for your reply. I'm assuming by what i've read in the article you gave me that in order for this to work i will be needing to purchase and download Nagios XI? I am currently using Nagios 3.0.6.

No, that's what I mean by "the first two pages apply equally to Nagios Core". The wizard stuff is only for XI, but the basic architecture applies to both - you just have to write your own configs manually.

Thank you soooo much Tony.. I'll start going through the article now.. I really do appreciate it. Don
Re: Nagios and SNMP
Ok. I guess i'm being dumb. I read through the link provided agove and am still having trouble. The link doesn't provde me instructions on pointing a switch thats sending the SNMP traps to the SNMP server and how to match the community strings. does anyone have any sample configs on how to do this? I am using Nagios3 with the SNMP plug-in. Thanks for any help given..

Re: Nagios and SNMP
I think this is all just done on the device end, and so you'd need to check the documentation for that. For instance, here's what it looks like for our Netgear switches:
I don't think there's any Nagios-end config about community strings when working with traps. Also, here's a config example for the service:
Code: Select all
define service {
host_name some-switch
name snmptrap_service
service_description SNMP Traps
max_check_attempts 1
check_interval 1
retry_interval 1
check_period 24x7
notification_interval 1
notification_period 24x7
contacts nagiosadmin
icon_image snmptrap.png
register 1
check_command check_dummy!0!"TRAP RESET"
is_volatile 1
initial_state o
active_checks_enabled 0
passive_checks_enabled 1
flap_detection_enabled 0
stalking_options o,w,u,c
parallelize_check 1
obsess_over_service 1
check_freshness 0
event_handler_enabled 1
process_perf_data 1
retain_status_information 1
retain_nonstatus_information 1
notifications_enabled 1
failure_prediction_enabled 1
}
