Manually 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

  • What 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.
  • Is 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.

     

  • I 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?).
