Measurements

The Telemetry service collects meters within an OpenStack deployment. This section provides a brief summary about meters format and origin and also contains the list of available meters.

Telemetry collects meters by polling the infrastructure elements and also by consuming the notifications emitted by other OpenStack services. For more information about the polling mechanism and notifications see telemetry-data-collection. There are several meters which are collected by polling and by consuming. The origin for each meter is listed in the tables below.

Note

You may need to configure Telemetry or other OpenStack services in order to be able to collect all the samples you need. For further information about configuration requirements see the Telemetry chapter in the OpenStack Installation Guide. Also check the Telemetry manual installation description.

Telemetry uses the following meter types:

Type	Description
Cumulative	Increasing over time (instance hours)
Delta	Changing over time (bandwidth)
Gauge	Discrete items (floating IPs, image uploads) and fluctuating values (disk I/O)

Telemetry provides the possibility to store metadata for samples. This metadata can be extended for OpenStack Compute and OpenStack Object Storage.

In order to add additional metadata information to OpenStack Compute you have two options to choose from. The first one is to specify them when you boot up a new instance. The additional information will be stored with the sample in the form of resource_metadata.user_metadata.*. The new field should be defined by using the prefix metering.. The modified boot command look like the following:

$ nova boot --meta metering.custom_metadata=a_value my_vm

The other option is to set the reserved_metadata_keys to the list of metadata keys that you would like to be included in resource_metadata of the instance related samples that are collected for OpenStack Compute. This option is included in the DEFAULT section of the ceilometer.conf configuration file.

You might also specify headers whose values will be stored along with the sample data of OpenStack Object Storage. The additional information is also stored under resource_metadata. The format of the new field is resource_metadata.http_header_$name, where $name is the name of the header with - replaced by _.

For specifying the new header, you need to set metadata_headers option under the [filter:ceilometer] section in proxy-server.conf under the swift folder. You can use this additional data for instance to distinguish external and internal users.

Measurements are grouped by services which are polled by Telemetry or emit notifications that this service consumes.

Note

The Telemetry service supports storing notifications as events. This functionality was added later, therefore the list of meters still contains existence type and other event related items. The proper way of using Telemetry is to configure it to use the event store and turn off the collection of the event related meters. For further information about events see Events section in the Telemetry documentation. For further information about how to turn on and off meters see telemetry-pipeline-configuration. Please also note that currently no migration is available to move the already existing event type samples to the event store.

Note

The instance:<type> meter can be replaced by using extra parameters in both the samples and statistics queries. Sample queries look like the following:

statistics:

  ceilometer statistics -m instance -g resource_metadata.instance_type

samples:

  ceilometer sample-list -m instance -q metadata.instance_type=<value>

The Telemetry service supports to create new meters by using transformers. For more details about transformers see telemetry-transformers. Among the meters gathered from libvirt and Hyper-V there are a few ones which are generated from other meters. The list of meters that are created by using the rate_of_change transformer from the above table is the following:

• cpu_util
• disk.read.requests.rate
• disk.write.requests.rate
• disk.read.bytes.rate
• disk.write.bytes.rate
• disk.device.read.requests.rate
• disk.device.write.requests.rate
• disk.device.read.bytes.rate
• disk.device.write.bytes.rate
• network.incoming.bytes.rate
• network.outgoing.bytes.rate
• network.incoming.packets.rate
• network.outgoing.packets.rate

Note

To enable the libvirt memory.usage support, you need to install libvirt version 1.1.1+, QEMU version 1.5+, and you also need to prepare suitable balloon driver in the image. It is applicable particularly for Windows guests, most modern Linux distributions already have it built in. Telemetry is not able to fetch the memory.usage samples without the image balloon driver.

OpenStack Compute is capable of collecting CPU related meters from the compute host machines. In order to use that you need to set the compute_monitors option to ComputeDriverCPUMonitor in the nova.conf configuration file. For further information see the Compute configuration section in the Compute chapter of the OpenStack Configuration Reference.

The following host machine related meters are collected for OpenStack Compute:

Name	Type	Unit	Resource	Origin	Note
**Meters added in the	Icehous	e relea	se or earli	er**
compute.node.cpu.frequency	Gauge	MHz	host ID	Notification	CPU frequency
compute.node.cpu.kernel.time	Cumulative	ns	host ID	Notification	CPU kernel time
compute.node.cpu.idle.time	Cumulative	ns	host ID	Notification	CPU idle time

compute.node.cpu.kernel.percent	Gauge	%	host ID	Notification	CPU kernel percentage

compute.node.cpu.iowait.percent	Gauge	%	host ID	Notification	CPU I/O wait percentage
compute.node.cpu.percent	Gauge	%	host ID	Notification	CPU utilization

Bare metal service

Telemetry captures notifications that are emitted by the Bare metal service. The source of the notifications are IPMI sensors that collect data from the host machine.

Note

The sensor data is not available in the Bare metal service by default. To enable the meters and configure this module to emit notifications about the measured values see the Installation Guide for the Bare metal service.

The following meters are recorded for the Bare metal service:

Name	Type	Unit	Resource	Origin	Note
**Meters added in	the Juno	releas	e**
hardware.ipmi.fan	Gauge	RPM	fan sensor	Notification	Fan rounds per minute (RPM)
hardware.ipmi.fan	Gauge	RPM	fan sensor	Notification	Fan rounds per minute (RPM)
hardware.ipmi.temperature	Gauge	C	temperature sensor	Notification	Temperate reading from sensor
hardware.ipmi.current	Gauge	W	current sensor	Notification	Current reading from sensor
hardware.ipmi.voltage	Gauge	V	voltage sensor	Notification	Voltage reading from sensor

IPMI based meters

Another way of gathering IPMI based data is to use IPMI sensors independently from the Bare metal service's components. Same meters as telemetry-bare-metal-service could be fetched except that origin is Pollster instead of Notification.

You need to deploy the ceilometer-agent-ipmi on each IPMI-capable node in order to poll local sensor data. For further information about the IPMI agent see telemetry-ipmi-agent.

Warning

To avoid duplication of metering data and unnecessary load on the IPMI interface, do not deploy the IPMI agent on nodes that are managed by the Bare metal service and keep the conductor.send_sensor_data option set to False in the ironic.conf configuration file.

Besides generic IPMI sensor data, the following Intel Node Manager meters are recorded from capable platform:

Name	Type	Unit	Resource	Origin	Note
**Meters added in the	Juno re	lease**
hardware.ipmi.node.power	Gauge	W	host ID	Pollster	Current power of the system

Ceph Object Storage

In order to gather meters from Ceph, you have to install and configure the Ceph Object Gateway (radosgw) as it is described in the Installation Manual. You have to enable usage logging in order to get the related meters from Ceph. You will also need an admin user with users, buckets, metadata and usage caps configured.

In order to access Ceph from Telemetry, you need to specify a service group for radosgw in the ceilometer.conf configuration file along with access_key and secret_key of the admin user mentioned above.

The following meters are collected for Ceph Object Storage:

Name	Type	Unit	Resource	Origin	Note
**Meters added in	the Kil	o release	**
radosgw.objects	Gauge	object	storage ID	Pollster	Number of objects
radosgw.objects.size	Gauge	B	storage ID	Pollster	Total size of stored objects

radosgw.containers.objects.size	Gauge	B	storage ID/container	Pollster	Total size of stored objects in container

Note

The usage related information may not be updated right after an upload or download, because the Ceph Object Gateway needs time to update the usage properties. For instance, the default configuration needs approximately 30 minutes to generate the usage logs.
