My systems are running monit 5.19. When I start Monit, I see the error syntax error 'status'
Status appears to be supported since 5.8 so I'm not sure what the issue is.
It is being caused by the following directive.
check host nlb with address host
if failed
port 443
protocol HTTPS
request "/healthcheck"
ssl options {verify: disable}
timeout 15 seconds
status = 200
then restart
