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 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 Installation Tutorials and Guides. 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:
$ openstack server create --property 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 Pipeline configuration. Please also note that currently no migration is available to move the already existing event type samples to the event store.

The Telemetry service supports to create new meters by using
transformers. For more details about transformers see
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
- cpu.delta
- 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.
Note
To enable libvirt disk.* support when running on RBD-backed shared
storage, you need to install libvirt version 1.2.16+.
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 cpu.virt_driver 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:

IPMI meters¶
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.
Alternatively, IPMI meters can be generated by deploying the ceilometer-agent-ipmi on each IPMI-capable node. For further information about the IPMI agent see 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.
The following IPMI sensor meters are recorded:
| Name | Type | Unit | Resource | Origin | Note |
|---|---|---|---|---|---|
| Meters added in the Mitaka release or earlier | |||||
| hardware.ipmi.fan | Gauge | RPM | fan sensor | Notification, Pollster | Fan rounds per minute (RPM) |

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.

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 |

update the usage properties. For instance, the default configuration
needs approximately 30 minutes to generate the usage logs.
