I am pretty new to the dude so excuse any daft statements.
I have had the dude running for 6 months or more with about 140 devices on and email me perfectly when they go down and come back up.
I added another 25 devices and only get an up notification from these new devices never a down.
I am using the same notification i have which still works and sends me down messages on all other devices no problem. Have I reached a limit on devices or missing something Daft?
I am using the exact same polling timing so I dont think there is an issue there. The devices in question (wireless routers) are external to the network but I also have other sets of wireless routers which report up/down no problem. I have tried setting the device as router / unknown but no differance there. Everything else is set as default and am only using the ping probe.
I have set a SMTP in main settings and manually on notifications although this has not resolved the issue either, have I hit a limit? thanks in advance.
There is no limit. I don’t know what you have missed but if you only set the main settings it is way easier to get every thing to do the same thing.
Make sure you have “unstable → down” set. The default for polling is 30 seconds and 3 retries. When a device misses a poll the first time the dude moves the device from up to unstable. Then after the next 2 are missed the device goes from unstable to down. So you might have selected up->down for these devices and they don’t do that by default they go from unstable to down. I can tell you for certain every time I manually configured a device with a different notification than the global one (which is active if you leave notification alone on the device) it has worked. Leave “notification” unchecked on the device unless you want it to run a custom notification.
Thanks for your reply. From your response I think I was doing two things wrong
I don’t have the unstable ticked just up and down.
Going into the device settings I am clicking use notifications thinking this would not if i ticked it although didn’t realise this uses the option when you first set the device up.
I followed your suggestion, added another main notifiction with the unstable in and this has proved successful after testing which now sends me an unstable, then a down message and up if applicable. Is there a method I can add which checks for the unstable but does not email me?
I figured out how to not send myself an email which I am sure is bread and butter to most but in my down notification that i normally send an email out I add the unstable > down which of course only sends one email out.
All my other notifications which just have an up or down are decent hp or cisco equipment, I guess as this was a cheap wireless zyxel router I had to do some fiddling, would be interesting to find whats missing on such devices.
