I'm running the dude 3.6 and haven't made any significant config change for quite some time. Recently I put a new ADSL router in and changed the SNMP OID it used by a probe to check the link speed. I use the probe to watch that OID to see if the link goes down (=0)
I don't know what has happened, but it was working fine but for the last few weeks now I only get email notifications when the service changes from down->up. I'm not getting notifications when it changes to unstable or down anymore. I've checked the notifications settings and it's ticked to notify on all actions, I tried unticking and retacking them all to "reset" the config, but it still doesn't notify. The email config works because I get the change to up emails no problems.
If link goes down, I see the device colour on the Map change to blue, but no notification until the service comes back up again.
I guess I've made some other change without realising it, but I can't figure out how to reset it or what to change to get it working again.
