health monitor to remove nodes from pool with no drian
Hello All,
We are running an F5 big IP 3600 series in front of a Windows web farm.
We are using automated deployments to each web node. In order to remove web nodes from the pool when deploying, I have setup health monitor that checks for the content of an .htm file on each node.
Send String
GET /maintenance.htm\n\n
Receive String
good
Receive Disable String
maintenance
This works well apart from active connections are still allowed, this means files are always in use etc.
I do not wish to wait for connections to drain or expire when this health monitor kicks in.
I would simply like to remove all connections and disable the node.
Any ideas how I can change this health monitor to do just this?
Kind Regards
- nitassEmployeehave you tried "action on service down"?
- Verbal_92765NimbostratusThis is set to 'Reselect' at the moment, but still active connections are coming to the node that has been marked down by the monitor.

- Verbal_92765Nimbostratusthe IIS logs on the web server were still showing active connections.
- koenning_107182Nimbostratusreject should sort all client initiated connections.
- Verbal_92765Nimbostratusi just tried reject and get the same thing
- Verbal_92765Nimbostratusfor example. If i stop the node on the command line with the command 'bigip node 192.168.0.x down' then there are no new connections.
- hooleylistCirrostratusDo you have other pools with that IP:port combination? Disabling the node would mark the server down in all pools, whereas marking a pool member down only affects that pool.
