[ovirt-users] Problem connecting to ovirt-optimizer machine

[Martin Sivak]

Hi everybody,

sorry to answer so late.

1) ovirt-optimizer 0.9 uses ovirt-engine-wildfly as the container. All log files should be in /var/log/ovirt-optimizer/jboss (as you probably know by now). The weird thing is that there is no ovirt-optimizer.log (it should have been there because of deployment descriptor that is present in /usr/share/java/ovirt-optimizer/jboss.war/WEB-INF or thereabout).

2) ovirt-optimizer will always report 404 for /ovirt-optimizer/result, you have to test with cluster ID: /ovirt-optimizer/result/<cluster uuid>

3) I see working optimizer in server-log:

11:40:40,019 INFO  [org.ovirt.optimizer.service.ClusterOptimizer] (Thread-63) New solution for 99408929-82cf-4dc7-a532-9d998063fa95 available (score 0hard/-859soft)

4) The deployment seems to be correct:

11:40:04,915 INFO  [org.apache.coyote.http11.Http11Protocol] (MSC service thread 1-2) Starting Coyote HTTP/1.1 on http--0.0.0.0-8080
11:40:11,067 INFO  [org.jboss.web] (MSC service thread 1-2) JBAS018210: Registering web context: /ovirt-optimizer


Can you recheck with the cluster UUID or check the browser's errors (javascript and network) console?
