Wide IP status calculation

Can somebody describe how is Wide ip status evaluating? What are dependencies on sub-components like Virtual server or monitors? What are the possible statuses and reasons?

 

  • The wide ip is a top level object that has no monitor directly attached. Therefore, it relies on a child object (pool) which itself relies on a child object (pool member, which in the case of GTM, is a virtual server on a BIG-IP or for non-F5 technology, a VS on another LB or just a server) to be available for a green status. Hopefully this table will help:

     

    Status Status Definition

     

    Available General: Child Monitor successful

     

    General: Parent At least one child is green

     

    Child - Node Most recent monitor successful

     

    Pool Member most recent monitor successful

     

    Pool At least one pool member is available

     

    Virtual Server At least one pool is available

     

    Unknown General: Child No associated monitor (or timeout of first check not reached)

     

    General: Parent All child objects are unknown

     

    Node No associated monitor (or timeout of first check not reached and not successful)

     

    Pool Member No associated monitor (or timeout of first check not reached and not successful)

     

    Pool All pool members are unknown

     

    Virtual Server All pools are unknown

     

    Offline General: Child Monitor failed

     

    General: Parent At least one child is red and no green or yellow children available

     

    Node Most recent monitor failed (no successful checks within timeout period)

     

    Pool Member Most recent monitor failed (no successful checks within timeout period)

     

    Pool One or more members are offline and no members are available

     

    Virtual Server One or more pools offline and no members available
