[Observium] monitor device by multiple ips

Hi All,

this is a daft random question, can i monitor a device via multiple ip addresses?

for instance, we have a site with a mikrotik router,

they currently have 3 internet lines (DONT ASK!) 2xADSL,1xFTTC

currently we use PPPOE on the router so we can see the mikrotik directly,

ive enabled SNMP remotely and i monitor the box via 1 of the ADSL lines, however its constantly goes up and down and never makes up its mind!

the other issue i have is the FTTC line is dynamic ip and never stays the same for more then 48hrs

so in my mind, /etc/hosts or DNS for site1.router goes to 1.2.3.4, 5.6.7.8, 9.10.11.12

then every check it always use one of three ip addresses ?

am i correct?

or is the another way of monitoring this device?

regards

Simon
