Identify which Cisco router is acting as primary

Hi,

I have 2 Cisco routers setup with HSRP; virtual IP 192.168.1.1
Router 1: 192.168.1.2
Router 2: 192.168.1.3

I would like to get your opinions on the best way to identify via a Network Monitoring service (Zabbix, PRTG, etc) which one of the routers is acting as primary i.e. routing internet traffic

Thanks

I guess you can monitor the ports on the switch where those routers are connected to, or configure 2 different netflow sessions from each interface and see the counters.

Understood. Thanks for the link anyways.

As a solution for now, I decided to monitor changes on the hostname of the virtual IP 192.168.1.1

SNMP OID 1.3.6.1.2.1.1.5.0 returns the hostname.

Thanks

As AlexBlinov told, you can monitor the router interfaces and based on the interfaces traffic statistics, you can identify the primary router.

But, if you would like to track/monitor the hsrp status, that's possible only to few platforms

So do your monitoring programs not work via SNMP and monitor HSRP State.

For more information on this, you can review the HSRP information located on the CIsco site.

Interesting. I took a look, but can't figure out what I need to monitor.
Presently, 192.168.1.2 is the primary and is acting as 192.168.1.1
Any ideas?

The 2 router acting as primary because it has higher priority value
