Nagios Trap Receiver - VIP/Load Balancer

[veeravamsi]

Hi Team,

Is it possible to have multiple Nagios Instances enabled to function as Trap Receiver in a Load-Balanced Way ??

Like Creating a VIP on Loadbalancer and add Nagios IPAddress:162 to redirect SNMP Traps incoming.

I couldnt find any documentation online so checking here.

--Vamsi

There is no inherent load balancing functionality built in for this.

It's not really load balancing but you could edit your /etc/snmp/snmptrapd.conf on each nagios server and add this:

Nagios A's snmptrapd.conf:

Code: Select all

forward default NAGIOSBIP:162

Nagios B's snmptrapd.conf:

Code: Select all

forward default NAGIOSAIP:162

Don't forget to restart the snmptrapd service on both:

Code: Select all

service snmptrapd restart

That way every trap one receives would be forwarded to the other as well.

Nice !! Does this help in Discarding the Traps on that Nagios Instance A where Host is not monitored ?

And accept only on Nagios Instance B where Host exists ?

Unfortunately, it doesn't discard the traps, it's just a way to forward the traps to another system.

You could technically do it by sending to the VIP and it should hit either server based on which node is active.
