Re: Metrics not accessible



No joy.
The cassandra pod starts fine but the hawkular on fails to start with what looks like the same errors as I described before.

I retried with the latest code and still hitting the same problem.
Metrics does not seem to be working with a new Ansible install.
I'm using a minimal setup with an inventory like this:
[OSEv3:children]
[snipp]

When the install completes the openshift-infra project pods ends up like
this:
NAME                         READY STATUS             RESTARTS   AGE
hawkular-cassandra-1-4m7lq   1/1       Running 0          16m
hawkular-metrics-0nl1q       0/1       CrashLoopBackOff 7          16m
heapster-cgw0b               0/1       Running 1          16m
The hawkular-metrics pods is failing, and it looks like its because it
can't connect to the cassandra pod.
The full log of the hawkular-metrics pod is here:
https://gist.github.com/tdudgeon/f3099911eed441817369ee03635aad7d
Any help resolving this would be appreciated.
I normally do the following.

oc scale rc/hawkular-metrics --replicas=0
oc scale rc/heapster --replicas=0
oc scale rc/hawkular-cassandra --replicas=0

after all pods are down start the new instaces.

Sometimes I must send a

oc delete pod <HANGING_POD> --grace-period=0

when a pod is hanging.

Now start cas

oc scale rc/hawkular-cassandra --replicas=1

Wait until cas is up without errors!

oc logs -f <NEW_POD>

Now run hawk

oc scale rc/hawkular-metrics --replicas=1

Wait until hawk is up without errors!

oc logs -f <NEW_POD>

Now run heapster

oc scale rc/heapster --replicas=1

oc logs -f <NEW_POD>

Does this help?
