hi Graham,
did you ever get anywhere with this? I tried out doing what I think you
mean and it seemed to work for me, just copying the definitions you gave in
your email, and picking Tomcat as the example cluster member type, as I
don't know what you are using - I substituted "http.port" for "ca.port".
Here is my complete blueprint
location: aws-ireland
name: test1
services:
- id: testcluster
type: cluster
initialSize: 2
memberSpec:
$brooklyn:entitySpec:
type: org.apache.brooklyn.entity.webapp.tomcat.TomcatServer
name: Tomcat
war: https://tomcat.apache.org/tomcat-6.0-doc/appdev/sample/sample.war
brooklyn.enrichers:
- type: org.apache.brooklyn.enricher.stock.Transformer
brooklyn.config:
enricher.sourceSensor: $brooklyn:sensor("service.isUp")
enricher.targetSensor: $brooklyn:sensor("cm_host_port")
enricher.targetValue: $brooklyn:formatString("%s:%s",
$brooklyn:attributeWhenReady("host.name"),
$brooklyn:attributeWhenReady("http.port"))
brooklyn.enrichers:
- type: org.apache.brooklyn.enricher.stock.Aggregator
brooklyn.config:
enricher.sourceSensor: $brooklyn:sensor("cm_host_port")
enricher.targetSensor: $brooklyn:sensor("cm_host_port_list")
enricher.aggregating.fromMembers: true
This deploys without anything hanging, and the "cm_host_port_list" gets
populated as you'd expect:
[
"ec2-54-246-234-162.eu-west-1.compute.amazonaws.com:8080",
"ec2-54-171-51-13.eu-west-1.compute.amazonaws.com:8080"
]
Is this like what you're doing, but it's hanging still for you?
cheers
