# Getting Started

With the OpenStack nova-compute and neutron-gateway charms:

```
juju deploy local:xenial/prometheus-openstack-exporter
```

This charm supports relating to keystone, but keystone-credentials
interface seems to be flaky, and hard to remove-relation, so the
charm works around this by adding ‘os-credentials’ setting as a YAML
dict (see setting description hints)

```
juju config prometheus-openstack-exporter os-credentials="{ ... }"

juju add-relation prometheus-openstack-exporter swift-storage-z1
juju add-relation prometheus-openstack-exporter swift-storage-z2
juju add-relation prometheus-openstack-exporter swift-storage-z3
juju add-relation prometheus prometheus-openstack-exporter
```

This charm needs some configuration to be manually copied from
nova-cloud-controller settings (as nova api doesn’t expose it):

```
juju config prometheus-openstack-exporter cpu-allocation-ratio=4.0 ram-allocation-ratio=1.0 disk-allocation-ratio=1.0
```

This charm provides two Grafana dashboards: **OpenStack Overview** and
**Hypervisor Overview**. They require at least Grafana v7.4.1 (current snap
7/stable).

The dashboards can be loaded by relating the charm to the Grafana one
with:

```
juju add-relation prometheus-openstack-exporter:dashboards grafana:dashboards
```

## Configuration Options

If you want to change the default instance size used as reference for number of
schedulable vms:

```
juju config prometheus-openstack-exporter schedulable-instance-size="1,2048,20"
```

If the cloud doesn’t support cinder / nova volumes, set this to “False”:

```
juju config prometheus-openstack-exporter use_nova_volumes="False"
```

## Juju resources support

The charm support juju resources, which is handy in offline deployments.
Prefetch the snaps:

```
snap download core
snap download prometheus-openstack-exporter
```

Provide downloaded snaps (prometheus-openstack-exporter\_25.snap and core\_7917.snap)
as resources to the application:

```
juju deploy prometheus-openstack-exporter \
--resource core=core_7917.snap \
--resource prometheus-openstack-exporter=prometheus-openstack-exporter_25.snap
```
