Nagios Support Forum

Hello
I am inexperienced with Nagios and SNMP in general and want to know if the is a quicker more efficient way to go about writing traps / service for a project i'm working on.

i estimate i have approximately 800 - 1000 traps to define and then the corresponding services .

------ Outline of Project -----

I have 40 cameras being monitored by 5 Video servers (8 cameras per server)
Each camera has 10 different alarm conditions (PASSIVE TRAPS) - power - tamper - runtime - service interal etc
can be either in a CRITICAL or OK State

so currently i have 40x10x2 ==800 traps to write (the way that i'm currently writing them)
but the format i'm using is the same for the snmp trap ie the Object of the netSnmpExampleHeartbeatName string "SITE ID_FAULT_STATE" see below.

Passive traps for these cameras are generated by the Video Servers and not the cameras
So these passive traps sent by the servers contain camera identifiers so i cannot use IP addresses

so an example of a trap being sent is power failure at camera ABC

snmptrap -v 2c -c public 192.168.xxx.yyy '' netSnmpExampleHeartbeatNotification netSnmpExampleHeartbeatName s "ABC_POWER_CRITICAL."
and the reset trap is
snmptrap -v 2c -c public 192.162.xxx.yyy '' netSnmpExampleHeartbeatNotification netSnmpExampleHeartbeatName s "ABC_POWER_OK."


so currently i am defining the traps as per below --

example power fault reset at site ABC

*********Edit Trap Definition***************************
Trap Details
Event Name:ABC_POWER_OK
OID:netSnmpExampleHeartbeatNotification
Category:Alarm
Severity:Ok
Description:camera power alarm reset
-------
Passive Service Setup
These inputs will also work with the EXEC macros table.
Enable Passive Service Setup:
Host Name: camera ABC

Service Description:POWER ABC
Severity:OK
Service Output: power fault reset
--------
Exec:
--------
Advanced
MATCH $1: (.*ABC_POWER_OK.$)

********************************************************************



this way i calculate approx 1000 definition have to be written but is the an easier way
800 + 200 more for server traps video stream traps

Please any help will be GREATLY appreciated

Unfortunately, there isn't a bulk method of doing this at this time because of the differences in each.

Hi

i can see that the defined traps are stored in /etc/snmp/snmptt.conf.nxti ------ see sample below
can i copy this file - rename -
then run a script that automatically copies the text but replaces the ZZZ with other site id's and add them to the file .

so once the new file with all 800+ defined traps included
can this be added back into the system.?

i have seen the warning saying that manually altering the file changes will be overwritten when Nagios restarts.
but i think i also think i saw a procedure to follow that this altered nxti can be implemented ..

also are there other files that would need updating ?

regards
Richie

HI richie7tech,

We're are currently working on your issue and are going to some research on this question with the team here and will follow up.

Thank you for your patience.

Yes, you can do that, just don't edit the /etc/snmp/snmptt.conf.nxti directly as it will be overwritten. Put your modified ones in a different file and then follow page 15 of this guide:
