Subject Re: [Proposal] Virtual Router service failure alerting
Date Thu, 13 Feb 2014 20:23:30 GMT
Hi Hari,

+1. Getting log from VR is a long awaited feature.

One correction: VR does have mgmt network nic, but it doesn't have direct
communcation with mgmt server(in the most case except VMware). So polling
is still needed.

And another comment: you can reuse CheckRouterTask() for the purpose. It
already has been used for s2s vpn connection status update and redundant
router checking, and "router.check.interval" would be used as interval for
checking. You can improve and reuse that rather than introduce another
polling thread for VR.

How can you define "new alart"? Did the file would be deleted/archived
after poll? Or you simply just looking after a certain point? I guess a
diff works better than search for timestamp. More details in implementation
would be helpful.
