Getting Started

Plugin collects metrics by communicating with OpenStack by REST API. It can run locally on the host, or in proxy mode (communicating with the host via HTTP(S)).

System Requirements

  • OpenStack deployment available
  • Supports Glance v1 and v2 APIs

Operating systems

All OSs currently supported by Snap:

  • Linux/amd64

Installation

Download the plugin binary:

You can get the pre-built binaries for your OS and architecture from the plugin's GitHub Releases page. Download the plugin from the latest release and load it into snapteld (/opt/snap/plugins is the default location for Snap packages).

To build the plugin binary:

Fork https://github.com/intelsdi-x/snap-plugin-collector-glance Clone repo into $GOPATH/src/github.com/intelsdi-x/:

$ git clone https://github.com/<yourGithubID>/snap-plugin-collector-glance.git

Build the Snap glance plugin by running make within the cloned repo:

$ make

This builds the plugin in ./build/

Configuration and Usage

  • Set up the Snap framework.
  • Create Global Config, see description in [Snap's Global Config] (#snaps-global-config).
  • Load the plugin and create a task, see example in Examples.

Suggestions

  • It is not recommended to set interval for task less than 20 seconds. This may lead to overloading Glance API with requests.

Collected Metrics

This plugin has the ability to gather the following metrics:

Namespace Data Type Description
intel/openstack/glance/<tenant_name>/images/public/count int Total number of OpenStack public images for given tenant
intel/openstack/glance/<tenant_name>/images/private/count int Total number of OpenStack private images for given tenant
intel/openstack/glance/<tenant_name>/images/shared/count int Total number of OpenStack shared images for given tenant
intel/openstack/glance/<tenant_name>/images/public/bytes int Total number of bytes used by OpenStack private images for given tenant
intel/openstack/glance/<tenant_name>/images/private/bytes int Total number of bytes used by OpenStack public images for given tenant
intel/openstack/glance/<tenant_name>/images/shared/bytes int Total number of bytes used by OpenStack shared images for given tenant

Snap's Global Config

Global configuration files are described in Snap's documentation. You have to add section "glance" in "collector" section and then specify following options:

  • "tenant" - name of the tenant, this parameter is optional. It can be provided at later stage, in task manifest configuration section for metrics.

See example Global Config in [examples/cfg] (examples/cfg/cfg.json).

###Task manifest User need to provide following parameters in configuration for collector:

  • "endpoint" - URL for OpenStack Identity endpoint aka Keystone (ex. "http://keystone.public.org:5000")
  • "tenant" - name of the tenant, this is required if not provided in global config
  • "user" - user name which has access to tenant
  • "password" - user password If you're using authentication API in v3 you need to set one of those two configuration options:
  • "domain_name" - domain name
  • "domain_id" - domain name

See example task manifest in [examples/task] (examples/tasks/task.json).

Examples

Example of running Snap glance collector and writing data to file.

Download an example Snap global config file.

$ curl -sfLO https://raw.githubusercontent.com/intelsdi-x/snap-plugin-collector-glance/master/examples/cfg/cfg.json

Ensure to provide your Keystone instance address and credentials.

Ensure Snap daemon is running with provided configuration file:

  • command line: snapteld -l 1 -t 0 --config cfg.json&

Download and load Snap plugins:

$ wget http://snap.ci.snap-telemetry.io/plugins/snap-plugin-collector-glance/latest/linux/x86_64/snap-plugin-collector-glance
$ wget http://snap.ci.snap-telemetry.io/plugins/snap-plugin-publisher-file/latest/linux/x86_64/snap-plugin-publisher-file
$ chmod 755 snap-plugin-*
$ snaptel plugin load snap-plugin-collector-glance
$ snaptel plugin load snap-plugin-publisher-file

See all available metrics:

$ snaptel metric list

Download an example task file and load it:

$ curl -sfLO https://raw.githubusercontent.com/intelsdi-x/snap-plugin-collector-glance/master/examples/tasks/task.json
$ snaptel task create -t task.json
