Subject Re: [Proposal] Virtual Router service failure alerting
Date Thu, 13 Feb 2014 20:45:54 GMT
Hari, 

You say that ³Virtual router does not have NIC for the management network
so VR cannot send alerts directly to management server and so it should be
polling process from management server to VR²
But there is a way to public an alert via CS WEB API. I¹ve added this
feature exactly to support the case when alert is generated by CS Service
running on a diff host. Please take a look, that might work for your
feature:

+Web+ROOT+admin+API



Thanks,
Alena.
