Are LTM monitors counted against the number of connections in Statistics?

Hello I just want to know if the monitors say http or https that are assigned to the pool...when they perform a health check are those requests counted in the statistics?...Like Max Connections or Bits in/out?

    i understand it is not counted.

     config

[root@ve11a:Active:In Sync] config  tmsh list ltm pool foo
ltm pool foo {
    members {
        200.200.200.101:80 {
            address 200.200.200.101
            session monitor-enabled
            state up
        }
    }
    monitor http
}
