openstack-exporter-k8s

Description

openstack-exporter-k8s is an operator to manage an openstack exporter on a Kubernetes based environment.

Usage

Deployment

openstack-exporter-k8s is deployed using below command:

juju deploy openstack-exporter-k8s openstack-exporter

Now connect the openstack exporter operator to existing keystone identity operators:

juju relate keystone:identity-ops openstack-exporter:identity-ops

Configuration

This section covers common and/or important configuration options. See file config.yaml for the full list of options, along with their descriptions and default values. See the Juju documentation for details on configuring applications.

Actions

This section covers Juju actions supported by the charm. Actions allow specific operations to be performed on a per-unit basis. To display action descriptions run juju actions openstack-exporter. If the charm is not deployed then see file actions.yaml.

identity-ops: To create admin user

OCI Images

The charm by default uses following images:

`ghcr.io/canonical/openstack-exporter:1.6.0-7533071`

Alerting Rules

This charm automatically adds Prometheus alert rules using the files at src/prometheus_alert_rules when related with grafana-agent. The following alerts are configured by default:

CinderStateWarning: This alert rule will trigger when a cinder service is disabled. The exporter generates metric openstack_cinder_agent_state which checks cinder service status. Alerts will appear if any Cinder service is found to be disabled.
CinderStateCritical: This alert rule will trigger when a cinder service is down. The exporter generates metric openstack_cinder_agent_state which checks cinder service status. Alerts will appear if any Cinder service is found to be down.
NeutronStateCritical: This alert rule triggers when a Neutron agent is enabled, but down. The exporter generates the metric openstack_neutron_agent_state, which checks the status of neutron agents. Alerts will appear if any neutron agent is found to be down.
OpenStackServicesDown: This alert rule will trigger when an OpenStack service is down. The exporter generates metrics that identify if services are up. E.g.: openstack_loadbalancer_up, openstack_designate_up. Individual alerts will appear if one of those services has problems.
NovaComputeDown: This alert rule will trigger when a nova agent (nova-conductor, nova-scheduler or nova-compute) is enabled, but down.
