CAS 6.2 Monitoring and Statistics

[Bryan Wooten]

We are trying to get the /status /health endpoints to work on the CAS 6.2 main branch following this guide:

https://apereo.github.io/cas/development/monitoring/Monitoring-Statistics.html

We have this in our pom.xml:

implementation "org.apereo.cas:cas-server-support-reports:${project.'cas.version'}"

Our cas.properties has:

#settings for monitoring and statistics
spring.boot.admin.url=https://cas6test.go.utah.edu:8444
spring.boot.admin.client.managementUrl=${cas.server.prefix}/status

management.endpoints.web.exposure.include=*
management.endpoints.enabled-by-default=true
cas.monitor.endpoints.endpoint.defaults.access=AUTHENTICATED

spring.security.user.name=casuser
spring.security.user.password=Mellon

I don't see port 8444 open using:

netstat -tulpn | grep LISTEN

In catalina.out I see:

 22-Jun-2020 10:53:21.601 WARNING [AsyncReporter{org.springframework.cloud.sleuth.zipkin2.sender.RestTemplateSender@1063035f}] zipkin2.reporter.AsyncReporter$BoundedAsyncReporter.flush Dropped 2 spans due to ResourceAccessException(I/O error on POST request for "http://localhost:9411/api/v2/spans": Connection refused (Connection refused); nested exception is java.net.ConnectException: Connection refused (Connection refused))

        org.springframework.web.client.ResourceAccessException: I/O error on POST request for "http://localhost:9411/api/v2/spans": Connection refused (Connection refused); nested exception is java.net.ConnectException: Connection refused (Connection refused)

                at org.springframework.web.client.RestTemplate.exchange(RestTemplate.java:644)

Any hints or clues? We need this as it seems to be a prerequisite for:

https://apereo.github.io/cas/6.0.x/monitoring/Configuring-Monitoring-Administration.html#configuration

Thanks,

Hi Bryan,

Are you using SpringBoot Admin Server? 

Here is how we have monitoring configured without SpringBoot Admin Server:

############## Management/Monitoring Settings ##############

# Blog post: https://apereo.github.io/2018/11/06/cas6-admin-endpoints-security/

# And https://apereo.github.io/2019/02/07/cas61-healthstatus-springboot/

management.endpoints.enabled-by-default= true

management.endpoints.defaults.sensitive= false

management.endpoints.web.base-path= /actuator

management.endpoints.web.exposure.include= info,health,status,registeredServices

management.server.add-application-context-header= false

management.endpoint.health.enabled= true

management.endpoint.health.show-details= always

management.endpoint.info.enabled= true

management.endpoint.status.enabled= true

management.endpoint.registeredServices.enabled= true

# basic auth to health and info used for ecs health check

cas.monitor.endpoints.endpoint.health.access=AUTHENTICATED

cas.monitor.endpoints.endpoint.info.access=AUTHENTICATED

cas.monitor.endpoints.endpoint.registeredServices.access=AUTHENTICATED

spring.security.user.name=${spring_security_user_name}

spring.security.user.password=${spring_security_user_password}

The monitoring endpoints do not listen on a different port, they are all part of the same application. 

Take a look at the linked blog posts in the code block also.

Hope this helps!
