Parent - Child Polling

RouterOS The Dude
1

I am using The Dude v2.2. If I set up a parent/child relationship between an AP and router, it seems like The Dude ignores the relationship and sends out notifications during the polling. It used to ignore the children if the parent was down. Can anyone confirm this?

Is it possible I get notified after it polls the parent and it goes down after it has been polled? I hate it if I reboot a core router, and the system sends out 300 notifications when the core router is the main parent in the tree. Same for a tower location. The main router in each tower is the parent for the APs, but if something happens to the core, I get notified for each AP as if the relationship didn’t exist.

Does the dude ever or eventualy see that the router is down or is it missing the outage during the reboot totaly?

Its probably timing related, have the dude check the router’s on the network more often or have the down count lower on the routers.

Thanks for the post. I watched an outage yesterday and what seems to happen is when the ping fails, it still sees the CPU as 0, and still up. They only turn orange, never “Down” status. Only the ping fails, and that is what I get notified of.

My experience is that devices with SNMP probes never go down (red), even though the device may actually be turned off or disconnected. Such devices will go partially down (orange) because the ping services (or something else) will fail, while The Dude will always feel the SNMP probes to be (incorrectly) up.

AFAIK this is a bug in The Dude… I’ve read others reporting this erroneous behavior.

Most of my custom snmp polls fail by timeout if the device is actualy down i sorta hate (feature request!) that if ping is down i get notified about rssi being down also. I think i have seen cpu stay up on a device thats down. What you could do if you were having problems like this is set up one device with just ping for the router and another with just cpu and that one can do the charting if you need that done and also set that cpu one dependant to the ping one and it will go down when the parent dies.
