Green all good host usable

 

Yellow application is being scheduled to go down only excisting sessions may continue

 

Red not available.

isn't it normal behavior when setting "Green" as receive string?

 

 

None (default)

 

LTM will continue to send data on established connections as long as client is sending and server is responding. Connection management / recovery / cleanup is via standard TCP mechanics for both clientside and serverside flows.

 

 

Use "None" if you don't want LTM to intervene in managing either side of the connection. Useful if your servers may not be accepting new connections, but should be allowed to continue servicing existing connections when marked DOWN. Also supports custom monitoring designed to support connection bleeding and other non-standard state management schemes.
