apdown alerts without a flood on capwap delay alerts

Is there a way of sending an alerts when an ap is down for 10 mins with on-premise HM?  We have enabled CAPWAP alerts, but just get flooded with hundreds, if not thousands of emails about 'capwap delay'.

Specifically what I'd like to configure, or see in future, is if that communication with an ap is lost for continuous 10 mins, then send me an email.

Is this possible?  What is the best way to be alerted when an ap genuinely has gone down?

Hello Michael,

In the soon to be released 6.1r6 version of HiveManager and HiveOS, you will have the ability to disable the reporting of CAPWAP delay alarm messaging at both the Network Policy and Device level. It is certainly helpful to know when there is high latency between devices and HiveManager, but it is understandably annoying to receive numerous messages if your devices are only say 10ms over the threshold.

As I mentioned, you will be able to disable these delay alarms at the Network Policy level under "Additional Settings > Service Settings"


At the device level under "Optional Settings > Advanced Settings"


As well as when selecting multiple devices at once under "Optional Settings > Advanced Settings"


There is no way currently to only receive an alarm message when a device has been down for X number of minutes, but hopefully by your being able to disable the unwanted alarms will achieve what you need.

Hope this helps

I should clarify my previous comment; there is no way to specify a time interval for when to consider that a device has been disconnected from the HiveManager on the Aerohive side. However, as Carsten points out there are certainly ways of achieving this level of reporting through 3rd party tools.

As of today, you need to use a 3rd party monitoring tool to achieve this behaviour. This requires fixed IPs for each AP (DHCP server reservations are sufficient) as well as SNMP enabled for the APs. You can then use a system like Nagios to monitor the APs, and you get much more information in addition. We use check_mk.

It would be nice to collect AP status information via SNMP from the Hivemanager only, and this might be available in future, but not today.

+1 for check_mk. I am using it, though not to monitor HiveAPs at the moment.
