Health Monitor a node on a pool

Hi

 

I'm doing migration from cisco ACE to F5 and facing a small issue How can I health monitor a specific node on a pool without put the monitor globaly on the node

 

So on the ACE we have a pool with two nodes each node have special monitor to a WAF server ( tcp monitor based on the destination IP and port to the WAF servers)

 

the WAF containe many services so in F5 if we put the monitor on the WAF node and one service fails it impact all the other

 

I need to monitor only one service for a specific pool, how can i do this ?

 

many thx

  • Hi Mouncefs,

     

    The way you can put a monitor into a POOL (which is not global is ) the following

     

    1. Main >> Local Traffic >> Pools >> (select actual pool)
    2. Select the monitor you want and move it from available to active

    If you want to only monitor it at the node level

     

    1. Main >> Local Traffic >> Nodes >> (Select Node)
    2. Click Health Monitors and select Node Specific
    3. Select the monitor to move it from available to active

    That is usually the 2 ways you can approah it.

     

  • Hi The Bhattman

     

    Thx for this answer but the idea is if I can put a special monitor for the node at the pool level and not inside the node it self

     

    example :

     

    pool80 have node1 and node2 , I have 2 monitor (tcp to destination WAF IP addresses and ports) M_WAF1_80 associated to node1 and M_WAF2_80 associated to node 2

     

    pool81 have the same 2 nodes and two new monitors M_WAF1_81 and M_WAF2_81 (the same WAF IPs and different port)

     

    if I put M_WAF1_80 and M_WAF1_81 on node1 and if port 80 goes down on WAF1 node1 will be desactivated on both pool80 and pool81 ... so pol81 will be impacted

     

    I need if port 80 failes on WAF1 only node1 on pool80 be desactivated

     

    Many Thx
