Openshift's hpessa-exporter allows users to export SMART information of local storage devices as Prometheus metrics, by using HPE Smart Storage Administrator tool. Those metrics (device status, temperature etc.) may hint administrators on potential up-coming failures.
Requires RedHat's Openshift (4.9+)
Apply the following configuration:
$ oc apply -f https://raw.githubusercontent.com/red-hat-storage/hpessa-exporter/main/deploy/hpessa-exporter.yaml
Or deploy directly from this repository:
oc apply -f deply/hpessa-exporter.yaml
Expect the following resources to be created:
namespace/openshift-storage-hpessa created
serviceaccount/hpessa-exporter created
role.rbac.authorization.k8s.io/hpessa-exporter created
clusterrole.rbac.authorization.k8s.io/hpessa-exporter created
rolebinding.rbac.authorization.k8s.io/hpessa-exporter created
clusterrolebinding.rbac.authorization.k8s.io/hpessa-exporter created
daemonset.apps/hpessa-exporter created
podmonitor.monitoring.coreos.com/hpessa-exporter-monitor created
Verify that exporter daemonset pods are up and running:
$ oc get pods -n openshift-storage-hpessa
NAME READY STATUS RESTARTS AGE
hpessa-exporter-2cbvl 1/1 Running 0 35s
hpessa-exporter-sk2cn 1/1 Running 0 35s
hpessa-exporter-v699z 1/1 Running 0 35s
Verify that each of the running pods exports local metrics
$ oc curl http://hpessa-exporter-<podid>:8080/metrics -n openshift-storage-hpessa
