Monit doesn't understand ssl or https

[Roland Giesler]

I have monit installed on Ubuntu 18.04 (some nodes are reporting to M/Monit), but a few test nodes are not yet and I'm trying to figure out how to monitor https services.

Firstly I'm trying to set the ssl option in /etc/monit/monitrc with:

 set ssl options {
     verify: disabled
 }

However, when I start monit with 

~# service monit restart

I get this result:

 * Restarting daemon monitor monit    

/etc/monit/monitrc:133: Error: syntax error 'ssl'

If I comment out the ssl configuration, I get an error at the first https reference.

The content:

check host FishEagle-Production with address 192.168.0.22
    if failed host 192.168.0.22 port 443 protocol https
    and request "/login"
    with timeout 25 seconds
    for 4 times within 5 cycles
    then alert
#port 443 protocol https
#    if failed port 443 protocol https with ssl options {verify: disable} then alert

The resulting error message:

~# service monit restart
 * Restarting daemon monitor monit

  /etc/monit/monitrc:338: Error: syntax error 'https'

So what could the problem be?  How can I check the https services?

thanks
