LDAPs Monitor now working

You're missing a few things:

1. Username is a full DN

2. You should probably leave Alias Address and Alias Service Port alone (*) since you're monitor is monitoring the actual pool members

Here's what my working monitor looks like:

ltm monitor ldap f5demo.com-ldaps-monitor {
    base cn=users,dc=f5demo,dc=com
    chase-referrals yes
    debug yes
    defaults-from ldap
    destination *:*
    filter objectClass=*
    interval 10
    mandatory-attributes no
    password $M$VM$6kCCg99I5iqVqeD1vhKWLw==
    security ssl
    time-until-up 0
    timeout 31
    username cn=Administrator,cn=users,dc=f5demo,dc=com
}
