F5 monitoring instance service

[ngockq]

Hi all,

I have a case about monitoring member in pool. I need a best monitor type for this case:

- I have a pool with two member server with monitor tcp on port 10222 for each member (node). LB method round robin.

- On each member (port 10222) have six instance service which deployed and Application Client outside call VS on port 10222. But when one of six instance failure, application client outside get error respone from F5 VS (but F5 healcheck port 10222 is alive and mark member UP and routing traffic normally).

- My question: how to monitoring instanse behind port service on each member to fix this issue?

Thanks very much

Hi @ngockq , 

what are type of these instances , it's another Ports ? such as Database port ? or what 

Also , you're creating now a tcp monitor with alias port 10222 ?

Hi Kansoh

It's not another port, just tcp port 10222. And monitor is template tcp monitor on F5.

Instances are thread flowing tcp port 10222.

Do you have any ideal about this?

Thanks

Hi @ngockq , 
you can create tcp monitor to monitor this port "10222" Specifically. 

here are the details :

That is same template tcp monitor ? Or something is difference?

Thanks

Hi @ngockq , 
No it's different as you'll add a customized port to make your F5 device monitor only on it.
that what i mean by Alias. 

IF port 10222 down in backend servers , F5 monitor will mark this pool member down. 
because it monitor now looks for TCP port 10222 only.
