+1 for protips on getting datadog to monitor openshift
I wasn’t able to get the datadog agent working with 1.4. I tried both of their out-of-the-box solutions for the k8s integration and no dice. Have yet to deep dive and investigate. The initial problem I ran into was their pre-baked monitoring daemonSet used hostPath volumes and I didn’t have them enabled. Once I did enable them the entire container filesystem was readonly and the datadog agent fell over when it tried to write to disk :\ I tried the other solution running the agent via docker cli and the container starts and appears to be working but no metrics are collected.

Can anyone point me at a guide for a good setup for monitoring and alerting when using Openshift? I have looked at DataDog but it looks like there is an outstanding bug in the k8s integration which prevents it working with Openshift installs. I also installed hawkular but it looks like there is no UI to configure alerts in place yet. Would anyone be willing to share their experience?

I'm hitting an issue around cadvisor not being available. I have read that cadvisor is available via kubelet as long as I'm using certs to access it. Does anyone know what the equivalent of the 2 URLs below are when trying to access via kubelet? - /api/v1.3/machine/ - /api/v1.3/subcontainers/ In general I don't think there is anything wrong with accessing cadvisor directly, except that I believe cadvisor isn't exposed from kubelets.... So i think, /stats/summary in the kubelet will externalize some of the cadvisor metrics you want. The thread below describes the idea behind stats as a cadvisor wrapper https://groups.google.com/forum/m/#!topic/kubernetes-sig-node/txBjT8-WvM0 Thanks, Dave _______________________________________________ users mailing list [email protected] http://lists.openshift.redhat.com/openshiftmm/listinfo/users _______________________________________________ users mailing list [email protected] http://lists.openshift.redhat.com/openshiftmm/listinfo/users
