No other feed back ?
Maybe we can start a survey :
What do you think about think about changing the current implementation by =
a
new one based on Shinken in the dev branch for Nagios 4?
1 : Stupid, useless and dangerous idea, we can still go on with the current
implementation
2 : Can be look at, but have very slow chance of success
3 : Great idea!! Why isn't it already done?
4 : Obi Wan Kenobi (you just do not care about this or you just hate
surveys)
Thanks,
