[sdnog] receiving snmp traps on cacti

[Ibrahim Tahir]

Dear Samir;
It is exactly as you described, you will need SNMPTT to convert the received traps into some action in Nagios(after editng the service and Nagios configuration). But the good news is that it translates both standards and non standards MIB files(I used it to translate vendor specific MIB files from Juniper and Cisco). However the system is truly resilient, for instance I configured the Nagios system with SMS and email notifications, and I typically receive them within 5 seconds from receiving the trap.
To setup the system is a true headache but to enjoy its capabilities is a totally different thing.

Dear Ibrahim

thank you for your valuable input. indeed cacti works by polling information using snmpget/snmpwalk. I was wondering since it's been there for a while if there is any plugin that can add the support for snmp traps.
I thought about Nagios but then I believe you need to install and configure SNMPTT (SNMP Trap Translator) and loads the MIBs to get a meaningful trap message.in addition to nagios configuration and service definitions.
I'm monitoring some vendor specific devices which uses non standard MIB files, that's why I thought about configuring cacti if there is a plug in that can do this
since everything is already configured with the host template.
but I guess I have to follow the "hard" approach 

thanks

Samir

Dear Samir;
I've used Cacti for quite long time to display the graphical data related to my network and system equipment. However I only use it for that purpose since my thoughts were based on the idea that Cacti is a polling system that fetches the data (Unlike the SNMP tarps model where the data is sent in asynchronous matter).
My solution for this dilemma was using a combined system of Nagios and Cacti, while Nagios is excellent in tackling alarms, notifications, and events(which Cacti greatly lacks) it is extremely poor in displaying the data in the graphical manner that Cacti does. So the combined system works by fetching the data by Nagios, and then passing it to Cacti.
I have some warnings regarding this approach, the installation and integration of this system is an extremely complex approach and would require an extraordinary amount of work. However it is really worth it, because you would use the full features of Nagios(one of the most powerful monitoring systems available) which contains more than 3000 plugins (handling SNMP Traps among them) while in the same time drawing the required data using Cacti.
I hope this help you 
Best RegardsIbrahim

Hi Fatima

Thanks for your help. However my problem is configuring my monitoring system (Cacti) to receive and display the snmp traps after I set them on the network devices.

Hi

I have a some network devices that are monitored through cacti
I know cacti works by polling through snmpget/snmpwalk. However is there a way to receive snmp traps on cacti 
so that I can in turn configure threshold/alerts for it ?

please let me know

Regards
Samir
