Close session health monitor TCP

Hi everyone,

 

I have a problem with F5 LTM. My application has only 1 session. I use health monitor port (health monitor TCP), Port is available. When application go through F5, session for health monitor is closed and F5 think port is unavailable, no traffic go through F5.

 

How can I fix this issue? I cannot add more session for application. Please help me!

 

Regards, Mai

    Not sure what kind of application system that you have. If there is any restriction on TCP session, you may configure for ICMP health monitor or ignore health monitor.

    I think the inband monitor can help you

     

    Performs passive monitoring as part of client requests. This monitor, when acting as a client, attempts to connect to a pool member. If the pool member does not respond to a connection request after a user-specified number of tries within a user-specified period, the monitor marks the pool member as down. After the monitor has marked the pool member as down, and after a user-specified period has passed, the monitor again tries to connect to the pool member (if so configured).
