Monitoring default routes switching via SNMP

Hello,
I am trying to figure out how to monitor switching between defautl routes in dual wan setup.
I have setup recursive routing for wan failover with tutorial from Mikrotik Failover setup for dual-WAN with DHCP clients
It works just fine however I would like to know if there is an option to monitor switching between default routes via SNMP? I cant seem to find the correct OID numbers. I am using Zabbix for monitoring do I would like to utilize it.

I know I can probably setup netwatch script that sends an email if WAN1 goes down, but as I said it would be nice to get it from SNMP polling.

Is ther any way to do that?

I have tried google/chat gpt but nothing seems to give me correct OIDs.
I know I can monitor roouting protocols like BGP or OSPF but cant seem to find anything with static routes.
I am using RouterOS 7.20.4

In Dude, I was able to find the oid for some routes, at first glance for dynamic ones.

but there is also a default static route there, the top one, has oid 1.3.6.1.2.1.4.24.4.1.16.0.0.0.0.0.0.0.0.0.192.168.88.2

Specifically, for the route highlighted in the screenshot, the oid is: 1.3.6.1.2.1.4.24.4.1.16.192.168.153.0.255.255.255.0.0.0.0.0.0

Thank you for your idea.
I was able to find OIDs for various routes even the default ones. However since I have two of them
1.3.6.1.2.1.4.24.4.1.13.0.0.0.0.0.0.0.0.0.9.9.9.9 = "-1" [ASN_INTEGER]
1.3.6.1.2.1.4.24.4.1.13.0.0.0.0.0.0.0.0.0.149.112.112.112 = "-1" [ASN_INTEGER]

I dont think there is a way to tell a difference which one of them i active and which one of them is not

First one has lower metric
2 As 0.0.0.0/0 9.9.9.9 main 1

Second one has higher for the failover to work

3 s 0.0.0.0/0 149.112.112.112 main 250

I cant seem to get OID correctly. I always get the sattus from SNMP for both routes with -1

Cant seem to find any information about it though

Just read docs,

and create your own script that return directly wich WAN is used.

Check this thread:

Maybe the info in #9 is useful.
