Monit IF/ELSE syntax - monit

Question

I attempting to monitor a service. My monit definition is below.
When I invoke monit -r I receive /etc/monit/conf.d/authentication.monit:10: syntax error 'else'
check host self with address myhost
start program = "/usr/bin/service start authentication"
stop program = "/usr/bin/service stop authentication"
if failed port 443 protocol https
request /
with timeout 5 seconds
for 2 cycles
then restart
if 1 restarts within 4 cycles then exec "/etc/monit/pagerduty-trigger authentication" else if passed for 2 cycles then exec "/etc/monit/pagerduty-resolve authentication"
All the documentation seems to indicate my syntax is correct.
I am attempting to follow the two docs
pagerduty
primary docs

Answer 1

Syntax is :
IF test THEN action [ELSE IF SUCCEEDED THEN *action]
Also
The "if x restarts within y cycles then ..." statement doesn't support the "else" part: https://mmonit.com/monit/documentation/monit.html#SERVICE-RESTART-LIMIT
Else for restart is a bit non-sense as there is no contrario for restart
I'm trying to get your logic here for the if then else actions but don't understand the else part.
Here you want to "stop then "start" service "authentication when https://myhost:443/ is failing two times (called T0)
Then on the next cycle, you want to run script /etc/monit/pagerduty-trigger authentication. (called T0 + 1 cycle)
Here why within 4 cycles but not less like 2, bot ok.
I suppose that on the T0 + 1 + 2 cycles, if service a online again, you want to run "/etc/monit/pagerduty-resolve authentication"
One solution is to handle it at your failed test level with custom scripts
if failed port 443 protocol https
request /
with timeout 5 seconds
for 2 cycles
then exec "/var/lib/monit/scripts/notifyAndExecute.sh"
else if succeeded then exec "/etc/monit/pagerduty-resolve authentication"
create file /var/lib/monit/scripts/notifyAndExecute.sh in charge of restarting and calling /etc/monit/pagerduty-trigger authentication

I'm not sure if you are still looking at this. I am also integrating Monit with Pagerduty. I have one simpler example which is working. What I note is the 'else' appears to only support "else if succeeded" . I think it is simply a long hand version of 'else' without to ability to add a more sophisticated expression that you are attempting.
Here is my example which triggers when service ( process in monit ) does not exist and resolves when it does.
check process tomcat8 with pidfile /var/run/tomcat8.pid
if not exist
then exec "/etc/monit/pagerduty-trigger tomcat8"
else if succeeded then exec "/etc/monit/pagerduty-resolve tomcat8"
