Openstack Exporter
We are using Prometheus for monitoring and metrics collection along with the openstack exporter to gather openstack specific resource metrics. For more information see: Prometheus docs and Openstack Exporter
Deploy the Openstack Exporter
Note
To deploy metric exporters you will first need to deploy the Prometheus Operator, see: Deploy Prometheus.
Create clouds-yaml secret
Modify genestack/helm-configs/monitoring/openstack-metrics-exporter/clouds-yaml with the appropriate settings and create the secret.
Tip
See the documentation on generating your own clouds.yaml
file which can be used to populate the monitoring configuration file.
From your generated clouds.yaml file, create a new manifest for your cloud config.
printf -v m "$(cat ~/.config/openstack/clouds.yaml)"; \
m="$m" yq -n '."clouds.yaml" = strenv(m)' | \
tee /tmp/generated-clouds.yaml
generated file will look similar to this
Add keystone certificates to the generated clouds yaml
ks_cert="$(kubectl get secret -n openstack keystone-tls-public -o json | jq -r '.data."tls.crt"' | base64 -d)" \
yq -I6 '."clouds.yaml" |= (from_yaml | .clouds.default.cacert = strenv(ks_cert) | to_yaml)' \
</tmp/generated-clouds.yaml | tee /tmp/gen-clouds-yaml
Now create a secrete from your manifest.
kubectl --namespace openstack create secret generic clouds-yaml-secret \
--from-file /tmp/gen-clouds-yaml
Install openstack-metrics-exporter helm chart
cd /opt/genestack/submodules/openstack-exporter/charts
helm upgrade --install os-metrics ./prometheus-openstack-exporter \
--namespace=openstack \
--timeout 15m \
-f /opt/genestack/helm-configs/monitoring/openstack-metrics-exporter/openstack-metrics-exporter-helm-overrides.yaml \
--set clouds_yaml_config="$(kubectl --namespace openstack get secret clouds-yaml-secret -o jsonpath='{.data.gen-clouds-yaml}' | base64 -d)"
