Drew,

The actuators are governed by spring authn. When not set, spring will create a 
random password. 
https://apereo.github.io/cas/7.3.x/monitoring/Configuring-SpringBootAdmin.html

We use a separate monitoring system that is used across all/most servers in out 
data centre. None of it relies on pulling data out of cas directly.

Subject: Re: [cas-user] 7.3.x Simple JSON Monitoring via Zabbix: HOW?

Thank Ray,
What do I need to know about configuring them that is missing from the 
documentation then? .....as getting 401s no matter what I do means that either 
(1) The documentation is incorrect, incomplete, or misleading; or (2) It 
doesn't actually work. I'm leaning toward (1), and to be frank this is likely 
the last generation of CAS the University of Maine System will ever implement 
because keeping it alive and fully up-to-date seems to require an increasing 
number of FTE over time.

The reason I'm asking about this is because:
(1) the documentation implies that configuring "Storage" for the Metrics is 
non-optional,
(2) Micrometer doesn't seem to have a pure simple JSON output (or if they do it 
isn't clearly mentioned in their documentation, unlike dropwizard metrics), and
(3) adding «implementation "org.apereo.cas:cas-server-core-monitor"» (which is 
in the Monitors section of the docs) to the Gradle build causes me to have to 
exclude things like datadog contrary to the documentation indicating the 
"simple" storage for Metrics (a different section of the documentation with a 
different Gradle configuration).is the default.

(3) is especially concerning, as it leads me to wonder "what depends on what" 
that isn't clearly documented and if there's more than meets the eye that is 
missing from the documentation.

Additionally, it seems that the authentication settings for the monitors and 
management front-end depend on a completely different authentication engine 
than the rest of CAS itself, as "AUTHENTICATED" doesn't seem to mean 
Authenticated.

Subject: [cas-user] 7.3.x Simple JSON Monitoring via Zabbix: HOW?

Here we use Zabbix as our monitoring platform. Is there some reasonable way we 
can just give it a JSON output to eat, or do we need to justify paying for 
something because our existing solution is no longer supported?
