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 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.

[[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
  ## 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

Documentation

Overview

Package openstack implements an OpenStack input plugin for Telegraf

The OpenStack input plug is a simple two phase metric collector. In the first pass a set of gatherers are run against the API to cache collections of resources. In the second phase the gathered resources are combined and emitted as metrics.

No aggregation is performed by the input plugin, instead queries to InfluxDB should be used to gather global totals of things such as tag frequency.

OpenStack is the main structure associated with a collection instance.

func (*OpenStack) Description 

func (o *OpenStack) Description() string

Description returns a description string of the input plugin and implements the Input interface.

func (*OpenStack) Gather 

func (o *OpenStack) Gather(acc telegraf.Accumulator) error

Gather gathers resources from the OpenStack API and accumulates metrics. This implements the Input interface.

func (*OpenStack) Init 

func (o *OpenStack) Init() error

initialize performs any necessary initialization functions

func (*OpenStack) SampleConfig 

func (o *OpenStack) SampleConfig() string

SampleConfig return a sample configuration file for auto-generation and implements the Input interface.
