# 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][juju-docs-config-apps] for details
on configuring applications.
### Actions
This section covers Juju [actions][juju-docs-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`.
## Relations
openstack-exporter-k8s requires the following relations:
`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.
