Probe #394 is reported as being down in the web GUI, but I can ping6 to it without a problem. I'm not near the probe right now, so I can't look at it or its traffic. Are there known cases where probes are alive but not reporting to their controllers?

There are a few scenarios when this is possible: * the probe is powered on, but it's not connected to the infrastructure (for example the connection went down for some reason, or after a reboot). In this case you can still ping it as the network stack is running, but it's reported as "down". * Every now and then we have issues with the controllers' network connections. They do reconnect themselves reliably, but if a probe connects to such a controller in the meantime, then the controller cannot report the probe status change to our database. A fix is in the making for this. On 2011.01.04. 10:38, Egor Zimin wrote:
I see the same situation with probe #163.
This probe seems to be up now. There are days when it fluctuates, but also periods when it's up for days. On 2011.01.04. 10:46, Piotr Strzyzewski wrote:
Maybe this is the right time to implement optional mail notifications about such events?
So you'd like to subscribe to notifications when your probe comes up or goes down? It's certainly possible to do this, but -- since probe reconnects are not really that serious events -- I think I'd rather want be notified if a probe was down for a non-trivial time. Cheers, Robert
