Plugins and Metrics

There are several plugins, mapping to each of the openstack components.

Find below a list of the available plugins and the metrics they publish.

  • cinder_plugin
    • openstack-cinder.<tenant>.volumes.count (number of tenant volumes)
    • openstack-cinder.<tenant>.volumes.bytes (total bytes of tenant volumes)

    • openstack-cinder.<tenant>.volume-snapshots.bytes (total bytes of tenant snapshots)
    • openstack-cinder.<tenant>.limites-{maxTotalVolumeGigabytes,maxTotalVolumes}
  • glance_plugin
    • openstack-glance.<tenant>.images.count (number of tenant images)
    • openstack-glance.<tenant>.images.bytes (total bytes of tenant images)
  • keystone_plugin
    • openstack-keystone.<tenant>.users.count (number of tenant users)
    • openstack-keystone.totals.tenants.count (total number of tenants)
    • openstack-keystone.totals.users.count (total number of users)
    • openstack-keystone.totals.services.count (total number of services)
    • openstack-keystone.totals.endpoints.count (total number of endpoints)
  • neutron_plugin
    • openstack-neutron.<tenant>.networks.count (number of tenant networks)

    • openstack-nova.<tenant>.quotas.{cores,fixed_ips,floating_ips,instances,key_pairs,,ram,security_groups} (quotas on each metric, per tenant)
    • openstack-nova.cluster.gauge.config-AllocationRatioCores (overcommit ratio for vcpus)
    • openstack-nova.cluster.gauge.config-AllocationRatioRamMB (overcommit ratio for ram - in MB)

    • openstack-nova.cluster.gauge.config-ReservedNodeRamMB (reserved ram per node - in MB)
    • openstack-nova.<hypervisor-hostname>.{current_workload,free_disk_gb,free_ram_mb,hypervisor_version, memory_mb,memory_mb_overcommit,memory_mb_overcommit_withreserve, memory_mb_used,running_vms,vcpus,vcpus_overcommit, vcpus_overcommit_withreserve,vcpus_used}

Requirements

It assumes an existing installation of collectd.

Check its documentation for details.

Setup and Configuration

The example configuration(s) below assume the plugins to be located under /usr/lib/collectd/plugins.

If you're under ubuntu, consider installing from this ppa.

Each plugin should have its own config file, under /etc/collectd/conf.d/<pluginname>.conf, which should follow some similar to:

# cat /etc/collectd/conf.d/keystone.conf

<LoadPlugin "python">
    Globals true
</LoadPlugin>

<Plugin "python">
    ModulePath "/usr/lib/collectd/plugins"

    Import "keystone_plugin"

    <Module "keystone_plugin">
        Username "admin"
        Password "123456"
        TenantName "openstack"
        AuthURL "https://api.example.com:5000/v2.0"
        Verbose "False"
    </Module>
</Plugin>

Puppet

If you use puppet for configuration, then try this excelent collectd module.

It has plenty of docs on how to use it, but for our specific plugins:

  collectd::plugin::python { 'keystone':
    modulepath => '/usr/lib/collectd/plugins',
    module     => 'keystone_plugin',
    config     => {
      'Username'   => 'admin',
      'Password'   => '123456',
      'TenantName' => 'openstack',
      'AuthURL'    => 'https://api1.example.com:5000/v2.0',
      'Verbose'    => 'true',
    },
  }

Limitations

The debian packaging files are provided, but don't expect the deb in the official repos.

Additional Notes

Ubuntu Packaging

These instructions should give full details.

In summary, do this once to prepare your environment:

pbuilder-dist precise create

and for every release (from master):

mkdir /tmp/build-collectd-os
cd /tmp/build-collectd-os
wget https://github.com/rochaporto/collectd-openstack/archive/master.zip
unzip master.zip
tar zcvf collectd-openstack-0.2.tar.gz collectd-openstack-master/
bzr dh-make collectd-openstack 0.2 collectd-openstack-0.2.tar.gz
cd collectd-openstack
bzr builddeb -S
cd ../build-area
pbuilder-dist precise build collectd-openstack_0.2-1ubuntu1.dsc
dput ppa:rocha-porto/collectd ../collectd-openstack_0.2-1ubuntu1_source.changes
