Is there a simple way to get the current attached volume state (think "space left on disk", or the opposite) ? Using stackdriver, this info is not provided. Not to be found neither within the gcloud console. I was wondering if this was accessible besides connecting to the instance and check it manually
Prometheus, Prometheus Operator, Alertmanager and Grafana
Depending on your Kubernetes version, you may use these very easy to install setups:
Prometheus 1.x link
Prometheus 2.x link
I recommend Prometheus 2
Check Prometeus.
At the moment this option is available through Kubernetes, but merely for the 1.8 version on. As you can check here there is a whole topic regarding this feature request and the code that implement these features.
Kubernetes 1.8 expose metrics for prometheus.
