Pools and virtual servers showing in red diamond

What could be the issue if all the pools (members too) and virtual servers created, is in red colour? I understand that the red color indicates that the server is down. I have given health monitors as "gateway_ICMP". I had a check in my server side and they're healthy in networking. They can ping their neighbor servers, as expected. Can anyone please help me what all checkpoints I need to consider for trouble shooting? It would be good if someone can reply me soon as my tasks are currently on hold..

  • Why gateway_ICMP please, for servers you'd typically use icmp or a application level monitor? I'd suggest you do a manual ping from the CLI of the F5 to the real servers and take it from there.

     

  • Which CLI access troubleshooting is virtually impossible. The best you can do is run a packet capture using an appropriate filter expression: Menu path: System > Support > TCP Dump.

     

  • i understand icmp monitor cannot be assigned to pool or pool member but gateway_icmp.

     

    as Steven suggested, i think it is better to do troubleshooting using command line.
