monitoring traffic in a redundant internet access
Hey team, question, is there a way to monitor in a mikrotik with two internet access if both are active? The main link will give us remote snmp access to the equipment but we need to know if there is a way we can verify that the 2nd link that is connected to a DSL modem is up and running.
Please advice,
Why not monitor the interface link status? Or set a threshold on traffic so when inbound traffic is zero you alert.

The link status will be UP since is connected to a DSL modem and the link is only used when the main access is down

Hi,
What´s the procedure to add MIB support for a device? I need to monitor some Packet Light DWDM, and I have the MIBs.
We are running Professional Edition.
Thanks. Regards.

Hi Luis,
The way I would go about it is to use one of the many Dynamic DNS services, there are plenty of example MikroTik scripts out there tuned for each Dynamic DNS service. Just ensure the IP interface that the script is using is the DSL one. You may need to use some packet mangling and routing rules to force this. The scripts I have used in the past assume only one connection to the Internet, but it wouldn't be hard with a bit of patience to modify the scripts to work with multiple connections.
This will then give you a fixed DNS hostname for your DSL link that you can add to Observium.
If your DSL IP is static, then depending on your ISP they may allow a DNS PTR record to be added. Some ISPs will do this, many won't, so the Dynamic DNS approach is the safest method.

You can use the check_ping probe for that.
As you monitor over the Internet you would need to sourceNAT the ping_probe traffic for the secondary remote WAN connection checks to another public ip on the Observium side and add a destination route for that sourceNAT’ed ip (host route) on the remote Microtik’s second WAN interface to avoid asymmetric routing.
hth, Alex
