Feature Request: Scheduled ADMIN_DOWN for Servers #1303

Open MattMills opened 6 years ago

MattMills commented 6 years ago

If it was possible for an Admin user to add a "maintenance" event to a server (Start time, stop time , required reason, username), that data could then be used so that when the server runs ORT within that time period the actual server status (if status == reported) is overridden with ADMIN_DOWN.

This would enable ops people to pre-program the network maintenance and other stuff we need to work around, as well as give us a fantastic way (much more visible) to keep track of it for troubleshooting purposes.

In the self service world, this could even be taken a step further of just giving the permission to setup maintenance periods to the networking team directly.

@dneuman64 @jhg03a - is this still required with the implementation of https://github.com/apache/trafficcontrol/blob/master/blueprints/multi-interface-servers.md

Server interfaces doesn't address this request

I agree with Jonathan, the intention is to provide a mechanism by which TC itself can be "aware" of expected periods of downtime and route around them with no other operator intervention.

agreed. just wondered if a server having multiple interfaces reduced the need to even admin down servers for maintenance purposes. i guess not.

This ticket is predicated on queue and snap being safe for automation to perform.
