There is a metric: __webapp.reqs.processingTime.fraction.windowed.perNode__ : ''Fraction of time spent processing reported by webserver (percentage, over time window) averaged over all nodes''
! NullPointerException: jmx port must not be null for Tomcat8ServerImpl
When I run a ControlledDynamicWebAppCluster with tomcat8 servers and the cluster is adding an additional server, this exception shows up.
Th Tomcat8 instance is ON-FIRE then, when you look at the sensors, it is indeed missing jmx stuff :
__First tomcat__:
||Name || Value
|jmx.agent.local.path |/home/brooklyn/brooklyn-managed-processes/apps/hYUOMMsL/entities/Tomcat8Server_N5oEPFyY/brooklyn-jmxmp-agent-shaded-0.8.0-incubating.jar
|jmx.context |jmxrmi
|jmx.direct.port|31003
|jmx.service.url|service:jmx:jmxmp://10.0.0.162:31003
|rmi.registry.port |1099
__Second (failed) tomcat__:
||Name ||Value
|jmx.context|jmxrmi
|rmi.registry.port|19099
The problem is intermittent.
Reported: [https://issues.apache.org/jira/browse/BROOKLYN-170]
! Runtime environments require internet access.
When you fire up a tomcat or nginx server, it (by default) downloads all binaries from the internet.
You can "work around" this, by providing tar.gz's in ~~brooklyn/.brooklyn :
{{{
/home/brooklyn/.brooklyn/repository/NginxController/1.8.0/nginx-1.8.0.tar.gz
/home/brooklyn/.brooklyn/repository/Tomcat8Server/8.0.26/apache-tomcat-8.0.26.tar.gz
}}}
But still during install it is performing apt-get updates, which will only work if you have internet access, haven't tested what happens if you run into a blocking firewall.
