NimbostratusManually re-add a member to a pool, after failing a health monitor
We have a request to have a health monitor do an http send string and expect receive string.
The odd part of the request is the app guys want the box permanently removed from the pool when it fails, and manually re-added (by an admin) after it starts passing a health monitor again. Is this easy, or am I overlooking the obvious?
This is an LTM version 9.3.1
Thanks
Michael_YatesWhat they are asking for is pretty easy to configure (I would advise them to think hard on doing this though...if all of the servers in the pool take a hit for some reason, then your site / application will be down until the servers are manually put back into service).
Local Traffic -> Monitors
Create Monitor -> Name Monitor
Manual Resume - Set to Yes.
Specifies whether the system automatically changes the status of a resource to Enabled at the next successful monitor check. If you set this option to Yes, you must manually re-enable the resource before the system can use it for load balancing connections.
No: Specifies that the monitor does not operate in Manual Resume mode.
Yes: Specifies that the monitor operates in Manual Resume mode.
Scott_Carlile_8Is that option available in 9.3.1?
All I see is under create monitor is:
Configuration:
Interval
Timeout
Send String
Receive String
User Name
Password
Reverse Yes No
Transparent Yes No
Alias Address
Alias Service Port
If it isn't available under 9.3.1, then I guess I should be upgrading soon.- Michael_YatesI thought it was. I have most of mine on v9.4.3 (I have three that are v10.1.x) and the option is available under Advanced Configuration.
Interval 5 seconds
Timeout 16 seconds
Manual Resume No
Send String GET /
Receive String
User Name
Password
Reverse No
Transparent No
Alias Address * All Addresses
Alias Service Port * All Ports

Manual Resume wasn't available in 9.3. I think it might have been added in 9.4.0 (or maybe 9.4.2?).
