# OpenStack Input Plugin

Collects the metrics from following services of OpenStack:

* CINDER(Block Storage)
* GLANCE(Image service)
* HEAT(Orchestration)
* KEYSTONE(Identity service)
* NEUTRON(Networking)
* NOVA(Compute Service)

At present this plugin requires the following APIs:

* blockstorage  v2
* compute  v2
* identity  v3
* networking  v2
* orchestration  v1

## Configuration and Recommendations

### Recommendations

Due to the large number of unique tags that this plugin generates, in order to keep the cardinality down it is **highly recommended** to use [modifiers](https://github.com/influxdata/telegraf/blob/master/docs/CONFIGURATION.md#modifiers) like `tagexclude` to discard unwanted tags.

For deployments with only a small number of VMs and hosts, a small polling interval (e.g. seconds-minutes) is acceptable. For larger deployments, polling a large number of systems will impact performance. Use the `interval` option to change how often the plugin is run:

`interval`: How often a metric is gathered. Setting this value at the plugin level overrides the global agent interval setting.

Also, consider polling OpenStack services at different intervals depending on your requirements. This will help with load and cardinality as well.

```toml
[[inputs.openstack]]
  interval = 5m
  ....
  authentication_endpoint = "https://my.openstack.cloud:5000"
  ...
  enabled_services = ["nova_services"]
  ....

[[inputs.openstack]]
  interval = 30m
  ....
  authentication_endpoint = "https://my.openstack.cloud:5000"
  ...
  enabled_services = ["services", "projects", "hypervisors", "flavors", "networks", "volumes"]
  ....
```

### Configuration

```toml
  ## The recommended interval to poll is '30m'

  ## The identity endpoint to authenticate against and get the service catalog from.
  authentication_endpoint = "https://my.openstack.cloud:5000"

  ## The domain to authenticate against when using a V3 identity endpoint.
  # domain = "default"

  ## The project to authenticate as.
  # project = "admin"

  ## User authentication credentials. Must have admin rights.
  username = "admin"
  password = "password"

  ## Available services are: 
  ## "agents", "aggregates", "flavors", "hypervisors", "networks", "nova_services",
  ## "ports", "projects", "servers", "services", "stacks", "storage_pools", "subnets", "volumes"
  # enabled_services = ["services", "projects", "hypervisors", "flavors", "networks", "volumes"]

  ## Collect Server Diagnostics
  # server_diagnotics = false

  ## output secrets (such as adminPass(for server) and UserID(for volume)).
  # output_secrets = false

  ## Amount of time allowed to complete the HTTP(s) request.
  # timeout = "5s"

  ## HTTP Proxy support
  # http_proxy_url = ""

  ## Optional TLS Config
  # tls_ca = /path/to/cafile
  # tls_cert = /path/to/certfile
  # tls_key = /path/to/keyfile
  ## Use TLS but skip chain & host verification
  # insecure_skip_verify = false

  ## Options for tags received from Openstack 
  # tag_prefix = "openstack_tag_"
  # tag_value = "true"

  ## Timestamp format for timestamp data recieved from Openstack.
  ## If false format is unix nanoseconds.
  # human_readable_timestamps = false

  ## Measure Openstack call duration
  # measure_openstack_requests = false
```
