We are excited to announce that we have launched our new Hive Community! HiveNation will remain as an archive, but all new posts, discussions, and articles will be created on Hive Community. You can visit our new community at thehivecommunity.aerohive.com
It appears that we have not (yet) assembled a breakdown for each alert classification. I'm on it. It will take some time for me to collate and annotate this.
In the meantime, attempting to address your specific question, if you are asking about the CAPWAP delay time alerts, our logic is
if the round-trip echo time exceeds ~60ms, then send a minor alarm. If it exceeds ~123ms, then send a major alarm. A critical alert is one that we deem needs urgent operator intervention to remedy (i.e. the CAPWAP connection between HiveManager and the managed device was broken).
